Hard water and coffee have always had a complicated relationship. Water is defined as hard because it contains high mineral concentrations formed when water passes through mineral deposits in its purification process, such as calcium and magnesium. Calcium and magnesium are salts that play a significant role in the taste of coffee and clogging of the coffee machine.

A machine with residual build-up requires regular cleaning, primarily if you use a machine that cannot handle hard water. So we are combining the best hard water coffee maker so that you can avoid that regular maintenance and waste of time when you could be enjoying that cup of coffee.

How To Select The Best Coffee Maker for Hard Water?

Hard water causes lime build-up that affects the coffee flavour. Therefore, this is a coffee-changing moment while making your choice. Before buying a good coffeemaker, it’s good to understand the impact of hard water on the flavour of the coffee.

Roasted coffee has many compounds that make the resulting taste, and so does hard water which has higher chemical compositions that impact its taste and usability. When these compounds mix, the resulting taste and smell are already compromised.

Many of the machines we have mentioned below are compact and readily available. However, you will want a machine that makes quality coffee without compromising the compound mixture.

What to look for when buying this machine

We have realized it would be easier if we compiled a list to act as a guideline during our research before you embark on your hunt.

The cost and value of the machine– buying a machine with water filtration fit for your cup of coffee should inversely be proportional to cost-benefit analysis.

What features would you like to see on your machine? – most machines are available with extra features which make the brewing process seamless. Yes, some may need a learning curve, but the result is what we are after.

The type of coffee you like using each morning- coffee is available in different packaging. Some use pods, while others use ground coffee. The type of coffee brew to be made is dependent on which method of brewing you prefer.

Timing- Everybody likes their coffee when it’s that time to boost. Some machines ease this by having delay timers to make coffee at the owner’s convenience.

How much coffee you consume- buying a 10-cup machine while you cannot finish one or two cups would be insane. Choose and only take what is made to suit your coffee cravings.

What carafe you want- the issue of durability arises and ease of cleanliness when you purchase a glass, thermal or stainless-steel carafe. Thermal and stainless may keep the coffee warmer for longer but are harder to clean. On the other hand, the glass carafe is easy to rinse but may be fragile.
