Just so everyone knows, if you're looking for a place to get your hands on some new gear and have access to things like tds meters and refractometers, Visions Espresso in Seattle has an open training lab for pretty much anyone. Just ask Cole McBride (@ColeCoffee on twitter) I believe his email is cole@visionsespresso.com.

Let me know if you would like to meet up too. I'll be there!
