StackExchange now has a beta website devoted to asking and answering questions about coffee, espresso and related topics.
If you’re not familiar with StackExchange, it’s a crowd-based Q&A site with many different topics. Originally it was for technology, but they’ve branched out into a variety of other areas.
So far there’s some interesting content, including whether there’s a difference between Greek and Turkish-style coffee preparation, what’s the deal with bulletproof coffee (answer: it’s really gross) and even non-coffee things you can do with an espresso machine.
It’s certainly worth checking out if you have an esoteric coffee question burning in the back of your mind — perhaps someone out there has the answer.
