The Right Way to Brew AeroPress Coffee_Which Coffee Beans are Best for AeroPress_Does AeroPress Coffee Taste Bitter

Start With Your Beans

My first suggestion is to get to know the flavor profile of whatever you have bought. Take FrontStreet Coffee's Huehuetenango — to me it shows the classic Guatemalan character quite strongly. In plain terms, it is fairly mellow, somewhat in the same family as FrontStreet Coffee's Brazilian beans, but not identical. Its most obvious trait is body: it coats the tongue noticeably and gives a creamy sweetness and texture (not literally whipped cream, of course). So those flavors are entirely normal in the cup, and the light acidity you taste is probably a byproduct of a lighter roast. Light-roasted beans have not fully gone through the Maillard reaction, which can leave some acidity in the final taste — also completely normal.

Coffee-to-Water Ratio

With bean character out of the way, let's talk ratios. The brewing device matters less than people think — it is just a tool that helps you get to a good cup. What really counts is the ratio, meaning the water-to-coffee ratio. The term should be familiar. If you want a proper glass of milk, the ratio of milk powder to water has to land where you want it, and coffee is the same: generally somewhere between 15 and 18 grams of water for every 1 gram of coffee. Too much or too little both hurt the flavor. It is not an absolute rule, but staying in that range makes a good cup much easier to hit.

Grind Size

Next, your grind size. Since you raised it, let me address it here. I have not used the Anonymous grinder, but I can give you a reference point for coarseness — every grinder has different markings, but the idea of coarse versus fine is universal. Grind your beans to the size of coarse sugar granules. Coarse sugar specifically. I am sure you know the texture I mean.

AeroPress Brewing Technique

Finally, how to actually use the AeroPress. It is genuinely simple, and your method probably has no major problems. First, pull the plunger to create the space you want, then set the filter paper in the cap and rinse it with hot water — make sure it is hot. Add the grounds to the brewing chamber, remembering that the chamber should be inverted at this stage. If you can, set it on a scale so the proportions are accurate. Then pour the water, keeping an eye on the ratio — you can figure the amount out in advance and pour to it.

Final Tips

One last note: because the AeroPress works like a syringe, treat the coffee like a patient. When you push the "medicine," do it slowly and at a steady speed, and everyone's cup will be better for it. Finally, watch the water temperature — around 90°C is best.

FrontStreet Coffee Recommendation

An AeroPress rewards a bean with good body and a forgiving, balanced profile, and FrontStreet Coffee's Brazil lineup is a perfect match. Our Cerrado Red Bourbon is a classic Brazilian single origin — half-sun (semi-washed) processed, medium roasted — with creamy peanut, toasted bread, caramel and hazelnut aromas, a round and mellow body, almost no acidity and a faint bittersweet edge. It works just as well in an AeroPress as in a pour-over, a moka pot, a siphon, a French press or a single-origin espresso.

For something sweeter and fruitier, our Queen Estate Yellow Bourbon from Mogiana on Brazil's fertile red volcanic soil is a rare mutation of Red Bourbon with an especially clean fruit character. Through an AeroPress it gives a sugarcane-like freshness you will not find elsewhere, alongside fruit and chocolate.

If you would rather build your cup around espresso, Brazilian beans also anchor every FrontStreet Coffee blend, from the creamy, nutty Classic Blend to the chocolate-forward Black Cocoa and FrontStreet Coffee's Commercial Blend made for cafés. They bring chocolate and butter aromas and a soft sweet-sour-bitter balance that keeps extraction stable, cup after cup.
