Which coffee is good for growing mushrooms?

We're often asked: Which coffee beans grow best on mushrooms? To answer this question, we've created the poll below. You can vote and share your experiences with a specific coffee, your favorite brand, or let us know if it didn't work on a particular coffee.

We suspect that the type of coffee, the roasting method, and the country of origin can influence fungal growth. With this poll, we might eventually conclude that certain coffee varieties stand out (positively or negatively), and perhaps coffee companies will then take action based on that.

So share your experience so we can make a difference together...
