Coffee is a staple of our mornings. It wakes us up, gets us going, and provides that much-needed caffeine boost to start the day right. Yet, sometimes even when we buy good coffee from a reputable roaster, it can still come out weak or watery. There are many reasons for this, but there’s no need to worry! Learn how to fix weak coffee with this blog now!

Why Does Your Coffee Come Out Weak?

Before diving into the solution, let’s take a look at the cause of weak coffee!

Inadequate Coffee Amount

When it comes to brewing coffee, there are many mistakes that people make. The most commonly occurring mistake is using too little or no water for steaming and boiling because this can lead you to an underwhelming cup of Joe.

When brewing with a french press, we recommend using 2 tbsp of coffee per 6oz. If you’re making an automatic drip brewer (most homes and offices have it) 1 tablespoon should work just fine! 

With their high-temperature brewing process, automatic drip brewers are able to extract more flavor from the coffee beans. We will explain it later in this post!

Improper Water Temperature

Not everyone brew coffee the same way. This is because it depends on a lot of factors like water temperature and grinds size, bitter or weak you want your cup to taste!

The water temperature you used during the extraction will determine how weak or bitter your coffee tastes! An easy way to ensure you have a strong cup of coffee in the morning is by making sure your water temperature doesn’t fall below 195 degrees Fahrenheit (or ~30 seconds off the boil).

Automatic drip machines are often the reason for bitter coffee. This is because they heat the water too high and over-extract flavor from beans, making the coffee bitter.

Inappropriate Coffee-water Ratio

You might find yourself drinking weak-tasting coffee if you don’t use enough of it while brewing. The reason is that the water dilutes your coffee flavor.

A lot of people don’t realize that the type and size of coffee maker they use will determine how much water is put into it. For instance, if you’re using a French press, then only pour enough to fill up about two-thirds or three quarters with liquid before adding more, whereas automatic drip coffeemakers require four cups worth per person (or 8 ounces each).

The ratios for brewing different coffee strengths can take some trial and error. However, if you like strong coffees, then the instructions may give a ratio that works best with your taste buds.

Short Brew Cycle

Coffee is a simple drink that has only two ingredients, but the interaction of heat, water, time, and ground coffee can all affect the strength/flavor of your cup of Joe.

The quality of your coffee will depend on the time you allow it to be steep. If there isn’t enough interaction between water and grounds, then what was intended as a perfect cup can be replaced by an underwhelming one instead!

Wrong Size Coffee Grinds

The size and consistency of your coffee grinds are important factors in determining how a cup tastes. If you want to get the best results, invest some money into buying yourself (or that special someone!) something nice like this excellent Coffee Grinder!

Grind levels affect the strength of your coffee, and too coarse a grind will leave you with weak brews.

The general rule is that if you’re using medium to fine ground coffees for espresso macchiatos and lattes. Going any finer would result in an underwhelming double shot hit from those grounds.

Unsuitable Coffee for Your Preference

If you’re looking for more bold flavors in your coffee, try a medium roast. This will bring out the chocolatey, nutty roasty goodness that is usually lost in lighter coffee.

How To Fix Weak Coffee?

This is the focus part of this blog. Let’s learn to fix your drink with four easy methods:

Add Instant Coffee

You may have noticed that adding a pinch of instant coffee can give your weak drink an unexpected boost in flavor.

Brew the Coffee Again

One way to get your coffee tasting better is by rerunning the brew cycle. In particular, use the already brewed cup of weak coffee and the same ground. This will pull any flavor left in them out!

“Dress Up” Your Coffee With Flavor Booster

A great way to enhance coffee is by adding a flavor booster. This will help hide any weak taste in your coffee and comes in handy if you are serving it as an average cup of Joe for guests.

It’s not just about adding milk and sweetener. You can experiment with different flavor combinations to make the plainest cup of coffee sound like it was made for royalty! Try mixing in some spices, caramel syrup, or vanilla French press, for example. A condiments tray is also a good idea, as your guests can freely pick the flavor they want. 

Serve Iced Coffee Instead Of Hot One

You can also fix weak coffee when you have guests over by converting it into iced coffee. The ice cubes get the blame for making your favorite drink too watery!

What Else Can You Do With Weak Coffee?

You do not need to pour away those weak coffee cups! Here are some good suggestions for what to do with them:

Make Ice Cubes With Weak Coffee

The best way to get your iced coffee game on point is by freezing the weak brew and making it into ice cubes. Plus, you can serve them in these pretty glasses!

Ice cubes are a great way to add some extra flavor and coolness to your iced coffee. You can use weak brewed coffee that has been sitting in storage for a while. Put those iced cubes in your coffee for a stronger favorable cup!

For a refreshing twist to your morning coffee, use the ice cubes in this recipe for an invigorating smoothie or frappe.

Cook Or Bake With Your Weak Coffee

You can still get some use out of those batches of weak coffee. 

Substitute other liquids with coffee water can add a new depth of flavor to your recipes! Try this method in salad dressing, frosting, coffee cake, brownies, rubs, and marinades! 

Serve Your Plants

If you have a weak batch of coffee that doesn’t taste quite right, try adding some acid-loving plants to your garden! Some plants that prefer acidic soils include holly, herbs, juniper, blueberry bushes, ferns and sedges, rhododendrons, oak trees, magnolia, azaleas, and orchids.

How To Prevent Making Weak Coffee?

It is also better to prevent the issue before it happens. Here are some notes for you!

Measure Coffee Grounds

Measure your coffee grounds to make sure that you are getting the perfect amount for each brew.

For iced coffee making, use the baking teaspoon and level each scoop so that the consistency of your drink will always be perfect for any time or occasion! 

There are special measuring scoops for iced coffee that help you make the perfect shot. These cups have both ounce weights and volume measurements in them, which makes it easy to regulate how strong your hot beverage is without worrying about being under.

Use More Coffee Per Cup

One of the most common mistakes that new baristas make is not adding enough coffee per cup. If your brews are consistently weak, try using a ½  or a full scoop in each pot until you find what works best for you!

You’ll want to find your perfect brew with those easy-to-use measuring spoon or coffee scoop.

Change The Roasting Type

Did you know that sometimes the wrong type of roast can make your coffee come out acidic or weak? For example, you might add a lot more scoops per 6oz but still have trouble getting enough flavor. 

It’s easy to fix, though! Just find what types of coffee work best for you and stick with them from then on out no matter how many cups are needed in order to get an enjoyable cup o’ joe!

As you may have guessed by the name, there are three main roasts of coffee: Dark, medium, and light. These different kinds can be further broken down into subcategories to help those who want more options when it comes time for their morning caffeine fix! 

If your favorite has always been light or medium roast, then try switching up with either a lighter/darker flavor profile that better suits what mood you’re in today. Even though these flavors might not be quite as strong, they still pack some mighty powerful punch.

Let Your Coffee Steep Longer

A French press is a great way to make strong, flavorful coffee. Try brewing longer or using cold brew if you want more of a bold taste with less caffeine – but don’t overdo it! Steeping your beans for just five extra minutes will give them plenty of time in hot water and help enhance things even further.

Don’t be afraid of the French Press! It takes time for coffee to steep, and if you push down too early, it can leave bitterness in your mouth.

Never Skip The Blooming Step

When it comes to making pour-over, French press, or cold brew coffee, there is one step you don’t want to miss out on – blooming. This technique helps bring out the flavors in your grounds by releasing carbon dioxide, which causes them to bubble up and gives off a great aroma!

Change the Filter

If you find that your coffee is too weak, then it could be because of the filters. Use high-quality ones and see if that helps!

Conclusion

So, how to fix weak coffee?

There are a few ways to fix weak coffee. The easiest way is to add more water or brew the coffee for longer in order to extract all of the flavors from it. You can also try using fewer ground beans, changing the grind size on your grinder, and/or brewing with hotter water. 

To make sure you don’t end up making weak coffee again, remember these tips when deciding how much grounds you need or what type of grind size would work best for your tastes!
