High Octane Compost

Something we have a lot of is, is spent coffee...

• Coffee grounds are a "green" or nitrogen source. C/N ratio about 20:1.
  

  While it is widely thought that they are acidic it has been shown that most of this acidity is removed in the brewing process.
  

  The exact pH of used grounds will depend on the pH and alkalinity of the water used in brewing, but with any potable water, used grounds will be close to neutral pH."

• Worms LOVE them!!! Use them in worm bin situations if you desire.

• The amount of grounds you would want to add to a compost pile is dependent on how many you may have available to you. If you were just using the amount that an average household might generate you should have no concerns. But some of you may have access to larger volumes and in that case you should limit the percentage to no more than 25% of the volume of the pile.
  

• Where might you find grounds? Well... unless you have been living in a cave, you may have noticed that there is an espresso stand within 100 yards of where you are currently standing. Starbucks has a waste reduction corporate policy... remind them if they don't want to give you grounds. Bring a bucket in the morning and pick it up at night.
