COFFEE & ALKALINE WATER

cup of coffee made using alkaline water

Is alkaline water good in coffee? Yes, alkaline water is great for coffee – it makes it taste better! Alkaline water extracts more flavor from coffee beans and makes a much better-tasting cup of coffee. For the best tasting coffee use alkaline water with a pH of up to 8.5. The science is there to prove it.


IS ALKALINE WATER GOOD FOR COFFEE?

water pouring into a pool of water

Yes, alkaline water is great for making coffee. If you like coffee, you’ll love alkaline water. Like Bonnie and Clyde, when you put the two together they form a potent couple.

Alkaline water intensifies the aroma and flavor of coffee. Its alkaline properties perfectly complement the natural acidity of coffee.

Coffee is an acidic compound and the addition of alkaline water balances the acidity to enhance the taste and bring the subtle flavors to the fore.

IMPROVES TASTE

Alkaline water increases the flavor of coffee. Alkaline water extracts more flavor from the coffee beans compared to regular water and creates a more fragrant beverage.

And the science is there to prove it. A study by the University of New South Wales found that using alkaline water improved the flavor extracted from coffee beans.

They concluded that water with a pH of 7.0-8.5 resulted in the most flavor extraction and the best tasting cup of coffee.  You can make alkaline water at home using an alkaline water machine.


HOW DOES ALKALINE WATER AFFECT YOUR COFFEE?

Alkaline water improves the taste, enhances the aroma, and neutralizes the natural acidity of coffee. It is a great choice of water for making coffee – and if you haven’t tried it yet, you should give it a go.

For the best results, choose an alkaline water with a pH of between 7 and 8.5. The pH scale runs from 0 to 14, and anything above 7 is alkaline.

Using alkaline water to brew your coffee takes the edge off its strong acidity levels and allows you better appreciate the complex flavors and aromas of the coffee bean.  Think of it like adding a little water to whiskey.

To truly appreciate the aroma of a high-end aged whiskey you need to add a little water to ‘loosen’ the flavors.  Alkaline water acts as the perfect counterbalance to the sharp acidity of a regular coffee.

It’s a real treat for the taste buds.  Discover more about the Benefits of Alkaline Waterover here.


WHAT ACIDS ARE IN COFFEE?

Coffee is a naturally acidic drink. It has a pH of 4.7-5.0 depending on the beans and brewing technique used. Anything below 7 on the pH scale is an acidic compound.

Coffee contains a wide range of acids, but the main players are chlorogenic, citric, malic, quinic, phosphoric, linoleic, and acetic acid. Alkaline water helps ‘balance out’ this acidity.

CHLOROGENIC ACID

This is the most prominent acid in coffee. It’s also what gives coffee some of its best flavors. It is found in higher concentrations in light roast coffee. It is a type of phenolic acid and may play a role in glucose regulation.

CITRIC ACID

This is another acid that is present in high quantities in coffee. It adds a pleasant fruity flavor to the coffee – an aroma that is favored by many. It is highly soluble and readily passes from the bean to water during the brewing process.

MALIC ACID

Malic acid adds a fruity flavor to the coffee similar to apples and plums. It is depleted during the roasting process – so the darker the roast the lower the malic acid content.

QUINIC ACID

Quinic acid is formed when chlorogenic acid is broken down during the roasting process. It is most noticeable in brewed coffee that has been left sitting on the heater too long and imparts a sour unpleasant taste.

PHOSPHORIC ACID

Phosphoric acid makes up less than 1% of a cup of coffee. However, it is one of the most potent acids found in coffee. And, it has no taste. It adds nothing to the flavor. It is believed phosphoric acid originates from the hydrolysis of phytic acid in the soil.

LINOLEIC ACID

Linoleic acid is a fatty acid. It is found in coffee in very low concentrations. The levels of linoleic acid in coffee are affected by the soil type and altitude at which the bean is grown. Linoleic acid is part of the omega-6 fatty acid family and is used to boost heart and blood health.

ACETIC ACID

Acetic acid is best known for the sharp bitter taste it gives to vinegar. It is found in coffee in low doses and gives it a sharp refreshing flavor. If the level of acetic acid is too high in a coffee it suffers an unpleasant vinegary taste.

WATER SOFTENER vs. WATER FILTER – WHAT’S THE DIFFERENCE?

ionized water in a glass

What’s the difference between a water filter and a water softener?  A water softener and a water filter are two very different devices.

A water softener reduces the hardness of water by removing dissolved calcium and magnesium. While a water filter purifies water by removing contaminants such as microbes and heavy metals.


IS A WATER SOFTENER THE SAME AS A WATER FILTER?

lady drinking ionized water

No, a water softener and water filter are two different devices that perform two different roles. A water softener is used to soften hard water – and a water filter is used to purify water by removing contaminants.

So, what’s the Difference Between a Water Softener & a Water Filter?


WHAT IS A WATER SOFTENER?

water ionization

A water softener is a device that reduces the hardness of water. Water hardness is caused by the presence of dissolved calcium and magnesium in your water source.

A water softener removes these dissolved minerals as the water passes through it and ‘softens’ the hard water.

Water becomes hard naturally as it passes through the earth and comes into contact with rocks. As it brushes against the rocks it absorbs calcium and magnesium. It is the accumulation of these materials that makes water hard.

Hard water has no negative impact on your health. Drinking it is not bad for you. In fact, it may be healthier than soft water due to its high mineral content.

However, it causes difficulty around the house – negatively affecting plumbing, kitchen appliances, and even laundry.

This is why some people choose to use a water softener to reduce the hardness of their water source.


HOW DOES A WATER SOFTENER WORK?

A water softener uses a mechanical process called ‘ion exchange’ to soften hard water. Hard water is funneled through an ion exchange chamber and emerges the other end as softened water.

So, what exactly is an ‘ion exchange’ and how does it work?

An ion exchange is simply a chamber that has been tightly packed with specially designed resin beads that hold an electrical charge.

When hard water flows through the chamber it brushes up against these beads making physical contact. The electrical charge of the beads attracts dissolved calcium and magnesium towards them and then locks them in place.

The water then emerges from the softener with a reduced level of calcium and magnesium. By reducing the level of calcium and magnesium minerals the water is softened.

The process uses sodium to create the electrical charge and remove the dissolved minerals. So, the downside to using a water softener is increased levels of sodium in your water.


WHAT IS A WATER FILTER?

glass of ionized water sitting on a rock

A water filter is a device that improves the purity of water by removing contaminants such as particles, microbes, heavy metals, pesticides, and other chemicals.

Water filters are used to provide clean water for many uses, including – agriculture, commercial industry, and public drinking water.

They can use any combination of four methods to remove contaminants from a water source – sieving, adsorption, ion exchanges, and biofilms.

In the home setting, there are four main types of filters to choose from – mechanical filters, absorption filters, reverse osmosis filters, and sequestration filters.

The most popular type is an absorption filter called an activated carbon filter. Activated carbon filters are great for removing chemical pollutants, particulates, and microbes.

The best water ionizing machines and alkaline water pitchers come with an activated carbon filter installed.  Check out the best ionized water filters of 2022 – click here.


HOW DOES A WATER FILTER WORK?

Each of the five domestic water filter types work in a different way.

MECHANICAL FILTERS

Mechanical water filters are the simplest of all. They use a physical barrier to remove sediment and suspended particles. They take the form of a mesh or a ceramic structure that physically blocks objects as the water passes through.

ABSORPTION FILTERS

Absorption filters work differently. They usually use activated carbon – a substance that has an enormous surface area. As water passes through the absorption filter it moves through a maze of contact areas.

Contaminants bind to the carbon and are held in place as the water moves through. Most domestic absorption water filters use granular activated carbon, ‘GAC’. It is an excellent filter choice for removing unwanted tastes and odors.

REVERSE OSMOSIS FILTERS

Reverse osmosis filters are used to remove dissolved inorganic solids from a water source. It uses a semipermeable membrane to remove contaminants.

Reverse osmosis is a highly efficient method of filtering water and achieves great results. It is often used in combination with other filter types to achieve the highest level of water purity.

SEQUESTRATION FILTERS

These filters work by chemically isolating a substance. They are not as popular as absorption filters and rarely seen in domestic appliances. They use polyphosphate to sequester calcium and magnesium minerals to reduce limescale and corrosion.

However, they do not reduce the ‘hardness of the water. To reduce water hardness a water softening device should be used.

frequently asked questions

Which Is Better – A Water Softener Or A Water Filter?

It depends on what you are trying to do. If you have hard water and want to soften it – use a water softener. If you are concerned about the purity of your water source and want to purify it to remove contaminants – use a water filter.

Does a Water Softener Filter Water?

No, a water softener does not filter water. It is used to soften water, that is – to reduce the hardness of water. To achieve this it removes dissolved calcium and magnesium but it does not filter out harmful contaminants such as microbes, chemicals, or suspended particles.

Does A Water Filter Soften Hard Water?

No, a water filter does not soften hard water. A water filter cleanses water by removing harmful pollutants such as microbes, chemicals, and suspended particles. Water filters are used to create clean safe water for industry, agriculture, and public use.

HOW TO TEST WATER HARDNESS AT HOME

glass of ionized water sitting on a rock

Testing water hardness at home is easy. You can use the simple ‘bottle and soap’ method or buy a hard water test strip kit online. Both methods are very easy to perform and take just seconds to show results. If you’d prefer a professional analysis you can send a water sample to a test lab.


TESTING WATER HARDNESS AT HOME

water in a glass with ice

There are several methods you can use to test the level of hardness of your water supply. The first two methods we will look at are DIY tests you can do at home.

They are easy to perform and will give you a good indication of the level of hardness of your water. The final method involves getting an accurate reading from a professional water testing lab.

1: BOTTLE & SOAP TEST

This is a really simple and cheap method to test for hard water at home. All you need is a clean transparent bottle – like a plastic water bottle.

Fill the bottle two-thirds with water. Then, add some liquid hand soap. It has to be regular soap – don’t use detergent or dish washing liquid.

Then, put the cap back on the bottle and shake it vigorously for 10 seconds. After shaking place the bottle on your countertop and take a look at the solution.

If a large amount of suds formed at the top and the water below remains clear – you have soft water. If little to no suds formed and you have cloudy water below – then you have hard water.

2: HARD WATER TEST STRIPS

A more accurate way to test your water is to use a hard water test strip kit. These kits are inexpensive and can be easily picked up online.

The testing process is simple. First up, remove one of the test strips from the pack. Then either immerse it in a glass of water or hold it under a running tap for a few seconds.

The test strip will then change color as a chemical reaction takes effect. All you need to do is compare the color against the color chart provided for your result.

This will give you a clear result and tell you if you have a hard or soft water supply in your home.

3: WATER TESTING LABORATORY

The most comprehensive and accurate method is to take a water sample and send it to a water testing laboratory for professional analysis. This method will take time to process and cost quite a bit more money.

Your best bet is to try the home DIY methods mentioned above first. Then, if you feel your water needs more comprehensive analysis – send it to a testing lab. They can also test for chlorine, nitrates, pH, heavy metals, and microbes.


WHAT IS WATER HARDNESS?

glass of alkaline water sitting on a table

Water hardness is the amount of dissolved calcium and magnesium in your water. Hard water has a high level of dissolved calcium and magnesium. And, soft water has a low level.

Hard water and soft water both look the same – so you won’t be able to tell them apart just by looking at them.

CALCIUM & MAGNESIUM

Water becomes hard when it absorbs calcium and magnesium minerals as it passes through rocks. It is a natural process and is very common across the United States.

Hard water is not bad for your health. In fact, it may even have some health benefits due to its high mineral content.

Water hardness is expressed in ‘grains per gallon’ or ‘milligrams per liter’. Hard water contains 7.0-10.5 grains per gallon.

SIGNS OF WATER HARDNESS

While hard water is not bad for your health it can lead to several problems throughout the house. The mineral high water can damage home appliances, clog your plumbing, and leave unwanted residues.

When hard water is heated it forms a white-colored deposit called limescale. You may notice limescale build-up in your kettle or dishwasher if you have a hard water supply.

Hard water also causes problems with your laundry. The minerals in the water interact with the detergent and stop it from working effectively. It can leave clothes feeling stiff and weaken fabrics – meaning clothes get worn out more quickly.


HARD WATER SOLUTIONS

So, now that we know what hard water is and the damage it can cause we need to know how to resolve the problem. How do you fix hard water?

For most people removing water hardness is not a priority. It does not damage our health and the minerals it contains may actually help us. And, it tastes better than soft water.

There are several hard water treatments you can use at home. The most effective option is to use an ion exchange water softener.

ION EXCHANGE WATER SOFTENER

This device uses a mechanical process where the hard water is feed through a collection of tiny plastic resin beads.

As the hard water flows through the beads an electric charge is used to attract the calcium and magnesium ions and then hold them in place. This way they are removed from the water.

The downside of using an ion exchange softener is that it adds sodium to your supply. As the hardness ions are trapped inside the device, sodium is released and added to the water.


WATER HARDNESS BY AREA AND ZIP CODE USA

If you are interested in reviewing your water hardness by location – the good people over at flixwater have created an online tool that allows you to do just that. Check it out – over here.

Interestingly, over 30% of cities in the US have a very hard water supply. while just 4% benefit from soft water. The city with the hardest water supply is Bullhead City on the banks of the Colorado River in Arizona.


frequently asked questions

How Can You Tell If Your Water Is Hard or Soft?

The easiest way to tell if your water is hard or soft is to perform the ‘soap and bottle’ test. Just put some water in a transparent bottle, add some hand soap and give it a good shake.

If very little or no suds form and the water looks a little cloudy – you’ve got hard water. If you’ve got lots of suds and clear water – you have soft water.

What Is A Good Number For Water Hardness?

Water hardness can be measured in grains/gallon, milligrams/liter, or parts per million. See the figures below for details on water hardness based on these values.

water hardness defined by measurement numbers

What Is The Unit of Water Hardness?

Water hardness can be measured in grains/gallon, milligrams/liter, or parts per million. In the US the unit used is grains/gallon (grains/gal), while in Europe milligrams/liter (mg/l) is the preferred unit of measurement.

What Is The Main Cause Of Hard Water?

Water hardness occurs naturally as water passes through rock formations in the earth. It collects calcium and magnesium mineral deposits as it comes into contact with rocks. And, it is the presence of these dissolved minerals in the water that causes hardness.

At What Hardness Do You Need To Use A Water Softener?

Most people do not treat water to remove hardness. Water hardness is not detrimental to your health. In fact, the presence of high levels of minerals might be good for you.

If you feel hard water is causing you problems you can choose to treat it at any stage. The most common way to treat a home water supply is to use an ion exchange water softener device.

How Do I Know If I’m In A Hard Water Area?

If you live in the United States you can check online to see if you live in a hard water area. There are several free tools you can use to check the city you live in or use your zip code. A quick google search will take you to one of these sites.

WHAT’S THE DIFFERENCE BETWEEN IONIZED WATER AND DEIONIZED WATER?

water pouring from a bottle

Ionized water has been through an electrochemical process to create alkaline and acidic water. Deionized water is a type of purified water that has had impurities called ions removed. They are two completely different types of water.

Don’t confuse ionized water with deionized water. They are two very different types of water. Ionized water is used to create alkaline and acidic water. While ionized water is a type of purified water that has had electrically charged molecules called ions removed.


WHAT IS IONIZED WATER?

glass of ionized water sitting on a rock

Ionized water is used to create alkaline water and acidic water. It uses a process called water ionization to turn regular water into ionized water.

It is a process used to create alkaline water and acidic water. These are collected separately and used for a range of popular household applications.

ALKALINE & ACIDIC WATER

Alkaline water has a high pH, falling between 7 and 14 on the pH scale. Alkaline water is popular for its potential health benefits which include better skin health, detoxification, and treating acid reflux.

Acidic water has a low pH, falling between 0 and 7 on the pH scale. It is used for household cleaning, sterilization, and skincare.


WHAT IS DEIONIZED WATER?

deionized water

Deionized water is a popular form of purified water. It involves removing impurities in the water called ions. The process is called water deionization.

For processes requiring purified water, these ions are regarded as impurities and need to be removed from the water. This is where ion removal or deionized water comes into play.

Ions are small particles that have an electrical charge. There are two types of ions in water, positive ions and negative ions. Positive ions are called ‘cations’ and negative ions are called ‘anions’.


WHAT IS IONIZED WATER USED FOR?

flow of water

Ionized water can be split into two groups – ionized alkaline water and ionized acidic water. Each of these has a distinct range of applications.

Applications of Alkaline Water

  • Drinking-Water
  • Potential Health Benefits
  • Cooking Vegetables
  • Making Tea & Coffee
  • Dyeing Fabrics

Applications of Acidic Water

  • Household Cleaning
  • Watering Plants
  • Disinfecting Utensils
  • Washing Dishes
  • Skin Care

WHAT IS DEIONIZED WATER USED FOR?

water pouring into a pool of water

Deionized water is a popular form of purified water used in many commercial and household applications. It is used in settings that require a relatively cheap and readily available form of purified water.  See below for a list of its most common applications.

Automotive
Deionized water contains no salts making it a great choice for automotive applications. Salts can damage engines, so deionized water is used in windscreen wash, radiator fluids, and anti-freeze formulas.

Aquariums
It’s clean, fish-friendly, and a great water for aquariums and marine tanks.

Beauty Products
It’s the go-to water base used in the production of shampoos, moisturizers, and skin cleansers.

Hospitals
Deionized water is a popular choice for cleaning jobs in hospital settings where water purity is vital.

Industry
Frequently used in industrial settings as a water rinse due to its high purity and very low salt levels. Salt corrodes and damages metallic equipment and fittings.

Laboratories
Many laboratory procedures require the use of deionized water in bench work and for cleaning utensils.


HOW IS IONIZED WATER MADE?

lasy drinking a glass of alkaline water

The easiest way to make ionized water is using a water ionizer. This a machine that takes regular tap water and converts it to ionized water.

The device used an electrochemical process to ionize the water and convert it into alkaline and acidic water. All you need to do is add water to the machine and let it get to work.

Using high conductivity electroplates it separates water into hydrogen and oxygen molecules. If there are a greater number of H+ ions than OH- ions the water is acidic.

If the number of OH- is greater than the number of H+ then the water is alkaline.  Check out the Best Alkaline Water Ionizers  – see here.


HOW IS DEIONIZED WATER MADE?

ionized water in a glass

Deionized water is made using an ion exchange resin. These resins contain tiny beads that have electrical charges that are used to attract and remove the ion impurities contained in water.

The positively charged beads are used to attract and remove the negative ions in the water. And, the negatively charged beads remove the positive ions in the water.

As the water passes through the filter resin both types of ion are held in place and the water is purified.

Ion exchange filters have a limited lifespan and lose charge as they purify water. They need to be replaced and regenerated when they reach the end of their life cycle.


WHAT ION IMPURITIES ARE REMOVED?

woman testing water in a lab

Regular water is full of ions that it picks up as it moves through rocks and passes through pipes. It collects these minerals naturally as it brushes up against them. Deionization removes these minerals using their positive (cation) or negative (anion) molecular charge.

Cation Impurities Removed

  • Magnesium
  • Iron
  • Calcium
  • Manganese
  • Hydrogen
  • Sodium

Anion Impurities Removed

  • Sulfates
  • Nitrates
  • Chlorides
  • Carbonates
  • Hydroxyl
  • Silica

THE BOTTOM LINE – THE DIFFERENCE BETWEEN IONIZED WATER AND DEIONIZED WATER?

lady making a hand gesture and smiling

Don’t confuse ionized and deionized water. One is used to create alkaline and acidic water while the other is a form of purified water.

Ionized alkaline water is a popular form of drinking water. While deionized water is used in many settings as a safe and cheap form of purified water with a very low salt content.
