Gemma Roaster

Gemma is an electric, fully automatic coffee roaster which doesn’t require knowledge in roasting coffee, thanks to the main control panel that allows selecting up to 10 different preset programmed type of roasting profiles, from light to dark roast. Those 10 programs can be changed, and adjusted at any time, based on your preferences. You may roast different batch sizes (250 grams, half kilo, etc… with the maximum of 2 kg (4.5 lbs)), with consistent results.
Our fully automated, countertop coffee roaster can consistently roast up to 4.5 lbs of green beans per cycle, has the capacity to produce over  100 lbs. of retail-ready coffee per day, enabling you to roast your own artisan coffee in front of your customers.

With the Artisan roaster from Sweet Coffee USA, newcomers will be roasting beans within 30 minutes after installation and ready to offer the best tasting coffee their customers have ever experienced.



Gemma ensures even roast development throughout each bean, resulting in pure taste at the desired roast profile.

  • Beans roasted gently inside & out
  • Chaff and small particles are blown away by air stream; not present later to affect taste
  • Narrow roast profiles attained (inside and outside of bean roasted to same degree)
  • No bitter or sour tastes
  • Consistency delivered by computerized roast master; same roast profile every time.

Easy to operate in

3 Simple Steps:

1st: Choose one of the ten pre-set programmed roasting profiles.

Gemma will start the pre-heating cycle.

2nd: Load the green coffee.

 When it reach the right temperature based on the roasting profile chosen, a warning sound will notify you to release the green coffee beans inside the drum.

3rd: Unload the freshly roasted coffee.

 It will take approximately 20 to 25 minutes until you will hear another beep warning you that the roasting is finished, and coffee is cold ( Gemma cools the coffee inside the drum).
