We’ve all been there: You open the lid to your coffee maker in the morning, and gross, there’s mold. Seeing mold in your coffee maker is not only an instant turn-off, but it’s also enough to get your day off to the wrong start. Instead of an efficient and caffeinated start to the day, you’re forced to scrub the machine and pot.

But is there a better way to clean your coffee pot? In this guide, we’ll break down what you need to know about how to clean a coffee pot for a fresher, healthier, better-tasting cup of joe.

Why cleaning your coffee pot matters

Although this may not be what you want to hear, cleaning your coffee maker should be a part of your regular maintenance tasks, just as you would clean the dishwasher from time to time. After all, your beans deserve as much.

When you fail to clean your coffee maker regularly, residue can build up and adversely affect the aromatics and flavor of your coffee. And this is the case for all kinds of joe, whether it’s a simple bag of pre-ground Dunkin’ coffee or the most expensive coffee in the world (although you’re hopefully treating the really good stuff to a Chemex or French Press).

Because coffee makers work with piping hot water, they tend to stay relatively clean. But that doesn’t mean you’re in the clear, as the coffee pot can become stained and other parts of the maker itself can become contaminated. After all, any environment that involves liquid can go sour and spoil.

Establish a routine for basic cleaning like you would a dirty dish after every use. For most coffee drinkers, this equates to a daily cleaning with dish soap and a little scrubbing. Use a fragrance-free soap so it does not change the nature of your coffee, and remember to clean beyond just the pot, like the lid, filter compartment, and water chamber.

Deep cleaning a coffee pot

It’s important to do a deeper clean every month or so. This one involves a cleaning agent with a bit more muscle, such as vinegar. You can use flavored vinegar like apple cider, but again, you’re working with coffee here, so keeping things as neutral as possible is often best to maintain the integrity of your morning cup.

For the best deep clean, take advantage of the coffee maker’s natural liquid circulation. Fill the maker with a mixture of water and vinegar (2:1) and pour it into the water trap. Press brew and let the vinegar work its magic. It will attack calcium deposits wherever it goes, leaving a squeaky clean chamber and coffee pot.

Allow the “brewed” mix of water and vinegar to set in the pot for 30 minutes to really clean out the base of the pot. Empty out the liquid then brew a pair of plain water batches (no coffee yet) to rinse the machine properly. After this, you’re back in business.

It’s work checking to see if your maker is dishwasher safe as well. Several brands now have makers that can break down and fit easily into your dishwasher at home. Cleaning in a dishwasher may result in a deeper clean than hand-washing, so it’s good to do both from time to time. Also, some newer coffee makers have a built-in clean function; however, they often don’t work as thoroughly as you might like.

Tips for easy coffee pot cleaning

There are some easy things you can do when it comes to healthy coffee maker upkeep. After your batch is brewed, empty the spent grounds. It’s all too easy to leave them in there, and if you end up going without coffee for a while or skipping town, they can invite mold and other bad stuff to grow in your maker.

  1. Keep your coffee beans in a clean environment as well. Sure, it’s just storage, but we are dealing with things we ingest. And, with coffee, there’s a sensitivity issue as the beans can take on unwanted odors or flavors or even lose some of their character if left, say, in too much direct sunlight.
  2. If you wish to do the deep clean with something besides vinegar (or baking soda), try an even ratio of water to lemon juice. Citric acid does wonders for sanitizing and can be preferable to some when going for a more natural approach.
  3. Although many people prefer to opt for natural coffee maker cleaners, some brands also sell pre-made coffee maker cleaners. One example is Affresh coffee maker cleaner tablets, which are ideal for cleaning single-serve coffee makers like Keurig coffee makers.

Is decaf coffee acidic? What to know before you make the switch
About the pH levels of decaf coffee

If you've been blessed with a stomach free of digestive issues, chances are you haven't given much thought to coffee's acidity. Yet, those of us with troublesome digestive systems know that coffee is an acidic drink with a pH level of 4.8 and 5.1, depending on the roast. The acidic nature of coffee can exacerbate various common conditions like IBS and acid reflux. I know this all too well as someone who drinks too much coffee daily.

Since giving up coffee is not an option, many wonder if switching to decaf is a good alternative. But is decaf coffee acidic, too? As it turns out, switching to decaf doesn't help much in lowering acidity. Here's what to know before you switch to drinking decaf.

Why you should try Vietnamese iced coffee (and how to make it yourself)
Vietnamese iced coffee

Even as someone well-versed in all things coffee, I had not heard of Vietnamese iced coffee until recently. As soon as I saw it on a coffee shop menu (ironically, while traveling to Punta Cana) for the first time, I was instantly intrigued. Vietnamese iced coffee, sometimes condensed milk coffee, isn't way different than traditional iced coffee. I went on a research expedition to learn about Vietnamese iced coffee, including what makes it unique and how to make it at home. Here's what you should know about this creamy, sweet, and icy variation of iced coffee.
How to make Vietnamese iced coffee

The traditional method of making Vietnamese iced coffee uses a special filter called a Phin. Using a Phin filter is the most popular way of brewing coffee in Vietnam, and it involves a method that closely resembles the way many Europeans and Americans brew and pour coffee over.

I view the process of grinding my own coffee beans as a privilege. While I sometimes opt for pre-ground coffee for convenience, grinding my beans enhances my coffee-drinking experience. Not only do the beans taste better and fresher, but there's something to be said about "working" for your cup of coffee, which makes it taste that much better.

There are ways to grind coffee without a coffee grinder, but if you've got a daily habit, it's best to invest in one. Many coffee drinkers know the debate of "burr grinder vs. blade grinder" never truly ends, as there are pros and cons to consider about both types of grinders. But how do you decide which coffee grinder is better for you? Let's compare burr grinder vs. blade grinder, considering the advantages and disadvantages of both.
