• Sweet Maria's is a supplier of green coffee and home coffee roasting machines, as well as a complete information source for your coffee roasting adventures!

  • Home roasting is easy! It only takes 5 to 15 minutes and your reward is the freshest coffee around. It requires no fancy equipment and green coffee from Sweet Maria's is half the price of good roasted coffee from a retailer.

  • We have a huge selection of green coffees, each carefully cupped and rated for quality.

  • We are more than just another online store, we are a virtual coffee university.

Aillio Bullet R1 Update.

Feb. 4, 2019: More Bullet roasters are on the way. They are currently in a shipping container, on a shipping vessel, somewhere on the Pacific. We expect to have them ready to sell in late Feb. Stay tuned. If you want to be notified when they arrive, you can sign up on our Bullet product page.


Jan. 7, 2019: Our last shipment of Bullets has sold out but we expect more this Spring (hopefully sooner). If you were able to order one from this past shipment, please take a few minutes to watch our unboxing video. Also note that your Bullet will ship with a replacement impeller fan that you should install in your machine. It only takes a few mintues. Watch our impeller fan replacement video for more info. You will also be the first to use the new infrared sensor that will give you readings for both the drum and bean temperatures. You can install the firmware for the new IR sensor here.
