Скачать или смотреть Popper is a Coffee Roaster: Roasting with Heat Profiles

Here's video suggesting some basic heat profiles to us in the Popper coffee roaster. Thompson used Artisan scope to trial about 30 different roast profiles in Popper (the latest version). The most basic approach, using 2 or 3 on the heat dial for the entire 7 minute roast cycle, produced some nice filter drip coffee results. But a different tact, starting the roast at 1 on the heat dial for the first 3 minutes, then adjusting upwards, made for a more balanced, mid-toned cup.

This same approach produced some astonishing results for espresso when extended out longer, to a 8-9 minute roast time. Toward the end we also bring up some important variables to watch out for: Voltage variations mean you might need to adapt these roast profiles to your own situation. And being consistent by weighing your batch is very important to getting good predictable results!
