I've heard a few good things about Intelligentsia coffee so I decided to order some. Once it arrived I tried it in my AeroPress and it turned out very, very sour. (several times)
Steps taken using AeroPress:
- rinsed filter
- used water that was 1 minute off boiling
- brewed for 1:30 total
- plunged just until I heard air through the filter
Coffee was so sour I couldn't finish it. Considering that I tried several times and that I've been using the AeroPress with great success for the past few months this has me very curious.
What makes a coffee turn out sour?
