CoffeeGeek - News, Reviews, Opinion and Community for Coffee and Espresso
Both good sites with forums and lots of equipment reviews. As far as equipment goes, keep in mind a minimal setup will be a 2-head commercial rated espresso machine and two conical grinders. Ball park $5K (used) for a decent espresso machine and $1K per grinder (one for regular, one for decaf). For commercial use, conical grinders are the only way to go. Fast and last a long time. Then there's the barrage of extra equipment - frothing pitchers, tampers, etc, etc.
I've never run a business, but I have a really nice espresso machine at home. Making a good cup of espresso isn't as simple as buying a machine, a grinder and some beans. The process is critical, as well as training your baristas. Here's some of the stuff that has to be taken into consideration:
- Setting the proper grind on your grinders so the espresso doesn't pull too fast or too slow (too fast and it's bitter, too slow and it tastes burn or over-extracted). You'll need to adjust your grinder daily to adjust for the change in your beans over night.
- Dosage - measuring your grinds consistently. Pack too many in one time compared to another will dramatically change your pour time (again, too fast or too slow affects the taste)
- Tamp - pressure drastically affects how fast a shot pulls. Many shops have bathroom scales so their baristas consistently put 30lbs of pressure. It's critical to push STRAIGHT DOWN as well... so it might be worth getting a lever activated tamper to take a variable out.
Geesh, I could go on... but go read coffeegeek - they have some great articles on the art of brewing a good cup - and an insane series on how to steam milk. Very technical. You wouldn't know it by watching the baristas at Starbucks murder their milk.
Definitely read up on the difference between a heat exchanger system and a double boiler - these are the two competing technologies used in machines for commercial use. Get a machine for home and experiment.
This is my machine:
Chris Coffee Service - La Spaziale Vivaldi II Single Group Dual Boiler
It is designed as a plumb-in model, but they have a Vivaldi 2 Mini which has a water reservoir if you don't want to plumb it in (keep in mind all commercial units will be plumbed in with dedicated power run to each unit).
Hopefully that gives you some of the basics and some direction. Good luck, and let me know where you end up so I can check out your place. I've heard the folks that run White Rock coffee are nice and are on this board, so they might be a good resource.
