Coffee Roasting[edit]

If you love coffee and you haven't yet tried roasting your own-- you're missing out! Roasting coffee beans in small quantities at home can be simple, quick, and low-cost.

Never been to Noisebridge before? the doorbell at the front gate!


There are many ways to roast coffee. The basic requirements are heat and motion.

A few things that work well:

  • cast iron pot and spoon
  • heatgun, metal bowl, and spoon
  • baking sheet in your oven
  • stovetop or electric popcorn popper
  • rotating metal drum over a barbecue

Helpful hints[edit]

  • Though it may be tempting to immediately drink coffee after you roast it, wait at least a few hours. The coffee will off gas and taste will improve considerably. Taste will peak over the next several days.
  • Coffee roasting can produce a bit of smoke. Make sure the area where you roast is well ventilated or use a fan if you roast indoors.
  • A lighter roast will preserve more flavor and character of an individual coffee, medium and darker roasts give beans a familiar 'roasted' flavor.

Where to get green coffee[edit]

  • Your favorite local coffee roaster (many will sell you beans at less than the cost of roasted)
  • Sweet Maria's - Oakland (you can pickup your order at their warehouse in West Oakland)
  • Burman Coffee - Online green coffee seller
  • Green Coffee Buying Club - Semi-structured online coffee buying club.
  • We live near a major port (Oakland). You can buy bulk from a coffee importer but most won't talk to you unless you are interested in a pallet of 75kg sacks. While the most economical, logistically this can be really annoying.
  • Royal Coffee a big specialty coffee importer in the east bay!
  • Some Ethiopian and Yemeni grocery stores sell green coffee!
  • Rainbow grocery (they sell green beans in a small jar in one of the bulk isles)
  • You can buy direct from farmers, including several in the US - kona coffee, even coffee grown in California!
