Coffee

I have yet to use a Moka Pot, but I have used it's hardcore big brother, the 9Barista Espresso "machine". I don't use it often because it's a bit of a pain in the ass, it takes like 10 minutes to make a single shot of espresso since there's no moving parts (except for the valves) and you have to heat up a huge chunk of steel on a stove. My brother looked it over and said it's essentially a reverse Whiskey still.

That thing can easily go from "this is pretty good" to "OMG WTF happened?!?" pretty quickly since it's damn near impossible to standardize all the variables (temperature, brewing time, grind size, bean type, water quality, etc..). I've had it for like 2 years now and it's pretty rare for me to have a good cup of espresso from one roaster to the next. I use Trade Coffee, so my coffee roasters are different with every bag I get.
