I bought anerobically fermented bean (usually they are aerobicly fermented) from Brooklyn coffee roasters. Different taste for sure...like old banana peels. But not entirely unpleasant.
Hmmm I wonder if those taste different than this other brand I found that uses some sort of enzyme fermentation method dayescoffee.com
Even without trying it I'm almost certain that dayes will taste better. The stuff I bought is probably done as a wild fermentation in hot temperatures. This makes the process unruly and variable, development of "off" flavors
