The Coffees of Indonesia; Sumatra (#)

  „Specially prepared Sumatras used to be a very, very difficult thing to find. Michael Sivetz, who basically invented the concept of air roasting that many home roaster's employ, has a section in his book Coffee Quality that bemoans the poor preparation of "Grade 1" Sumatras. But it is also true that the inclusion of unattractive coffee in some of those Mandhelings gives them their "oomph!" Take them out and you can actually have an overly-prepped Sumatra, a cup without the exotic "forest floor" earthiness and deep husky flavors that define the origin character of this coffee. That's the danger of the Triple Picks.“

Roasting with a Heat Gun: A Top-Down Approach (INeedCoffee.com)

  „Roasting with a heat gun is another variation of the fluid bed method used in most home roasting appliances. I'm told a Sivetz sample roaster actually uses a heat gun to blow air up through beans held in a metal tube. The method I'm going to talk about is throw some beans into a bowl and blast them with a heat gun. It sounds like something you would see on Tool Time but it really works.“

  „"Coffee roasting is an art form, is it not?" Darn straight it is! But think on this: As a coffee roaster, you are not trying to create an original piece of work with each roast. In fact, just the opposite.“

CoffeeKid - A Home Roasting Primer

  „Hearthware, happy with the small success their Gourmet model was having, developed their first 3rd generation machine - the Hearthware Precision. The brains of that roaster featured a built in roast profile following the SCAA's recommended roast cycle, and it actively controlled the air volume and heat temperatures. No more "dumb" roasters - they were getting brains now!“
