Equipment FAQ

Some espresso machines have pumps, and some don't.  Why?  Does it matter?
Yes it does matter, and I'll explain why.  The water is supposed to be between 190 and 204 degrees Fahrenheit (88 to 96 Celsius) as it is forced through the coffee in the filter basket.  Machines without a pump simply use the pressure of the boiling water to force the water through.  But what temperature does water boil at?  Yep, 212 degrees Fahrenheit (100 Celsius, obviously.)  But that slight heat problem isn't the only issue here.  You see, the water is supposed to only touch the coffee for around 25 seconds.  (No, I don't know what that is in metric time, sorry.)  Now most machines without pumps can't get the water through nearly that quickly -- which results in a much more bitter shot of espresso.  On the other hand, pumpless machines typically cost as little as $40 USD.  They also make great Christmas gifts, which means that you'll find a couple working pumpless espresso makers at any thrift store or flea market in the entire western world.

Could you tell me about model ____ espresso machine/grinder/etc?
No.  If I had enough money to go test every espresso machine ever made, don't you think I'd be paying you to clean my shoes with your tongue?  Seriously though, if you want to buy me a something and have me test it, by all means contact me!

What's with the name "group," as in group handle, group area, etc?
I've wondered that too.  If you happen to know the answer, please go ahead and contact me.
