    What does good coffee water taste like?

    The best way to answer this without boggling your mind and making you crazy is your water should have a blank or neutral taste. This will really complement the flavors from your coffee beans, and your homemade brew will taste just like your local coffee shops!

    In order to understand what’s the best water to use, we need to breakdown the different kinds of water available for brewing coffee.

    Is it OK to use distilled water to make coffee?

    Distilled water is water that has been boiled to vapor and then condensed back to liquid. This is a common method of purifying water in regions where tap water isn’t safe to drink. Most bottled water is distilled. But distilled water lacks minerals like calcium and magnesium otherwise found in tap water, and these are great allies for coffee.

    So is distilled water suitable for brewing coffee? I wouldn’t recommend it because it lacks essential minerals that help to extract the coffee beans into the water.

    Tap Water

    Using tap water for your coffee can be the easiest solution, but with ease comes sacrifice. As mentioned above, this kind of water contains compounds that can drastically alter the flavor of your coffee. Remember, a high mineral content means more extra flavors, and we want neutral water.

    So tap water may be more accessible to you, but all of those minerals are going to restrict the potential of your coffee beans. If you have the patience and the desire to make a great cup of coffee, don’t use tap water. Especially if you hate cleaning your espresso machine.

    Bottled Water

    If you’re interested in brewing a good cup of coffee without adding any new appliances to your kitchen, then bottled water may be the way to go. However, this can get expensive because now you’re dealing with more packaging. So if you already tend to have a lot of bottled water on hand, I recommend using it.

    Remember that not all bottles of water are created equal. Some might hive a higher mineral content than others. The kind of water bottle you choose can alter the taste of your coffee.

    Filtered Water

    Since most people are using tap water for their coffee brewing, using filtered water will really make your cup of coffee stand out. The filtering process will remove all those nasty acidic compounds and leave you in love with your morning brew.

    Using filtered water is not only going to make your coffee taste better, but it’s also better for your health. Unfiltered water contains toxins that can have negative long-term effects on your health.

    Filtered Water

    Hard Water vs. Soft Water

    When on the subject of water, there is more than just filtered and unfiltered, or salt and fresh water. We also have hard water and soft water. No, hard water isn’t ice, that was also my first thought.

    Hard water

    The hardness of water is determined by the amount of calcium and magnesium contained inside. Calcium and magnesium are very coffee friendly minerals. So hard water would contain more of these minerals.

    Soft water

    Soft water, on the other hand, contains less calcium and magnesium. But soft water is higher in sodium.

    So do we use hard or soft water in our coffee? Well, unfortunately, the answer to this isn’t one-sided. Instead of choosing hard or soft, it’s about finding the right balance that you enjoy when sipping your morning coffee.

    You may read a lot that you want to soften your water for brewing, but that can give your water a salty aftertaste. However, if your water is too hard you may deal with more bitterness. The right balance depends solely on your preferred taste.

    The Difference Between Reverse Osmosis and Distilled Water

    In most cases, experts would consider a reverse osmosis (RO) water better than distilled. Though both are considered “filtered water”, RO systems don’t require any electricity and are easier to maintain. This makes them a great addition to your home for long term healthy drinking water. RO systems help by leaving a coffee-friendly mineral content.

    How do you know if you have a water problem?

    Not every time you come across a bad batch of coffee is the water to blame. Sometimes using the wrong grinder, or choosing the wrong beans can put you in a bad spot.

    Since most people neglect the quality of their water when making coffee, they never realize why their coffee tastes worse than their local barista’s – even if they are using the same beans!

    1. Experiment brewing with different kinds of water – Make about 3 different batches. You can try one with spring water, another with bottled water and perhaps distilled water for the third. This will reassure you that it’s not your beans, but it’s your water.
    2. Make sure your coffee maker is clean – This may seem like a no-brainer, but some people leave their coffee makers uncleaned and unloved. This can make a huge negative impact on your coffee quality.
    3. Ask your local barista – Since most people are in the coffee industry are passionate about their products, they don’t mind sharing a tip or two. Ask your barista if you can try the water they use and then compare it with what you have at home.

    Often times when people are brewing coffee, they focus too much on the coffee beans and not enough on the whole process. There are a lot of steps that go into a godlike cup of coffee, and you just need to have the patience to spot them out.

    To take home…

    Coffee is 98% water, so choosing the best kind is essential for brewing a perfect batch. The chemistry behind water may not be all that interesting, but it’s an essential component of the coffee brewing process. I’m a big believer that the more you geek over something, the better outcome you will get. If you really want to make top-notch coffee, you need to look into every detail.

    Every good batch of brew starts with good water. As seen above there are tons of cool gadgets you can add to your home to help get the purest water possible. Next time before you start your coffee routine, take a sip of the water you using and if anything tastes off or funky, try going with something different.
