Is My Aeropress Too Loose? A Coffee Enthusiast’s Guide to Perfect Brewing

Hello fellow coffee lovers! It’s another day, another brew, and today I’m going to address one of the most common questions I get from my readers: “How do I know if my Aeropress is too loose?” This may seem like a minor concern, but trust me, it can have a major impact on the quality of your coffee. So without further ado, let’s dive in.

First, let’s clarify what we mean by a “loose” Aeropress. We’re not talking about the physical structure of the machine. Instead, we’re referring to the pressure and seal created when you brew a cup of coffee. Basically, if you find it’s too easy to plunge, or if coffee drips through before you plunge, your Aeropress may be too loose.

Signs that your Aeropress is too loose

1. Coffee drips before plunging

The first and most obvious sign is if your coffee starts to drip through the filter and into your cup before you’ve even started the plunging process. This could be a sign that the seal between the plunger and the chamber isn’t quite right, and the water is finding an easy path through your coffee grounds.

2. It’s Too Easy to Plunge

The Aeropress works on the principle of air pressure. You should feel some resistance when you submerge. If it feels too easy, like there’s no pressure building up, or if it takes less than 20 seconds to submerge, your Aeropress is probably too loose.

3. Your coffee tastes weak or watery

Your taste buds don’t lie. If your coffee tastes weak, watery, or lacks the depth and richness you usually enjoy, it could be a sign that the water is passing through the grounds too quickly and not extracting enough flavor.

How to fix a loose Aeropress

Don’t worry, a loose Aeropress isn’t a death sentence for your coffee routine. Here are a few recommended fixes:

1. Check your grind size

A common cause of a loose Aeropress is the grind size of your coffee. If your grounds are too coarse, water will easily pass through without extracting enough flavor. Aim for a grind slightly finer than sea salt.

2. Pre-wetting the filter

Before adding your coffee, place the filter in the cap and run it under warm water. This will help create a better seal and prevent premature dripping.

3. Adjust the plunger

If you’re finding it too easy to plunge, try adjusting the plunger. Before adding your coffee and water, insert the plunger into the chamber and pull it up slightly to create a better seal.

4. Use fresh coffee

Old coffee tends to create less resistance during brewing. Always use fresh coffee whenever possible to ensure a good seal and pressure during brewing.

5. Replace the rubber gasket

If you’ve tried all of the above and are still having problems, it may be time to replace the rubber seal on your plunger. Over time, these can wear out and no longer create a good seal.

Final Thoughts

The beauty of the Aeropress is its simplicity and adaptability. A loose Aeropress is a common problem, but with a little adjustment, you can be brewing that perfect cup in no time. Remember, brewing coffee is a personal journey. Experiment with different variables, take notes, and most importantly, enjoy the process.

Here’s to brewing better, one cup at a time!


How do I know if my aeropress is too loose?

About 20 seconds to push the coffee through the aeropress with light to moderate pressure (just leaning on the plunger) would be a good time. Your description of the water passing easily at first and the plunger being “too loose” sound like your coffee grind is too coarse.

How do I stop my aeropress from leaking?

Quote from video: You turn it upside down and the seal in the plunger solves your problem. The second is to keep it right side up but we’re going to stick the plunger back in while it brews.

Why is aeropress dripping?

It is to be expected that a small amount of coffee will drip through the paper filter as it sits in immersion. However if your coffee is dripping though the Aeropress far too fast (ie you are losing over half of the total liquid before plunging) you should try grinding your coffee a bit coarser.

How should aeropress coffee be ground?

For the best AeroPress coffee grind size, we recommend a consistency similar to table salt. On a coffee grinding chart, this is considered medium-fine. Each particle will be about 0.5 mm in diameter and falls between the fine espresso grind and the slightly coarser grind used in cafetière coffee.

Why is my aeropress coffee weak?

How long your coffee is submerged in hot water will affect the flavor. Extraction too short, and your coffee will taste sour and weak. Too long, and your coffee will taste bitter and murky.

When should I replace my Aeropress?

The Aeropress Plunger

One of the parts that will require replacement in your AeroPress is the rubber seal (also called the plunger). The newer ones are actually made of silicone. When taken care of properly, this part should last two to three years.

How much water does an Aeropress hold?

The Challenge, The Approach

Here’s the issue: the Aeropress can only hold ~250ml of water at a time (roughly 8oz). In order to brew two cups of coffee, you have to be able to brew ~430ml in one session.

Should you wet Aeropress filter?

We recommend you don’t skip this one! Rinsing your paper filter helps reduces the papery or woody flavor taste. The best way to get it wet is to put the dry filter into the AeroPress’ black filter basket and place it over a cup, which also pre-heats your cup—win, win!

What should Aeropress coffee taste like?

The Aeropress is an immersion brew method. Unlike a French press or toddy system, it uses finely ground coffee and a short brew time. The pressure produced from plunging further improves extraction and flavor, and is what gives the brewed coffee a strong flavor that is reminiscent of espresso.
