Replace your French Press with a Pour Over and start save money

Do a Google image search for “things that absorb water” and you will find plenty of sponges and paper towel companies to choose from. Fascinating stuff right? But did you know that coffee absorbs water too? This doesn’t seem very interesting either, until you learn that this may actually impact the taste of your coffee and keep a few extra bucks in your bank account over the long haul. And lets face it, we don’t plan on stopping our coffee passion anytime soon!

One of the most popular ways to make coffee is with a full immersion brew method, such as a French Press or Aeropress, where coffee and water are in contact together for a set amount of time. Oppositely, with drip coffee (pour-over or Chemex), water flows through a bed of flavorful coffee and into your mug with less contact time. Logic would seem that the full immersion brew method would make a much stronger cup of coffee — and it does, sort of.

On average, coffee absorbs double that number in water. This means that 15 grams of coffee will absorb roughly 30 grams of water. Another way to explain this is 230 grams of water poured over 15 grams of ground coffee will yield 200 grams of hot coffee in your final cup.

Now that you know that coffee absorbs water let’s look at a recent test performed by Matt Perger at Barista Hustle. After brewing the exact same ratios for both full immersion Aereopress and pour-over, he used TDS to calculate their strength. He found that the pour-over was actually 15% stronger then that of the Aereopress. But why? Wouldn’t the coffee in direct contact with water for a longer time produce a stronger coffee? Yes. But when that 15% (or 30 grams) loss of strong coffee water is not in the final cup, you have a weaker coffee.

This means that you will use 15% more coffee to get the same strength as that of a pour-over. If you get coffee delivered every other week at $17 x 2 per month = $34 x 12 months = a savings of roughly $60 a year. THEREFORE, it makes more financial sense to use a pour-over coffee over another full immersion brews!
