In it, Peter talks about native forests vs planted forests and the differences

I'm so excited for you to join me in this discussion about terroir. Terroir comes from latin, for terra - soil.

Today's episode is part 1 of a 2 part series talking about the people who pick our coffee.In episode 15 we went deeply into how a molecule of sucrose in the coffee cherry pulp becomes a flavor compound like banana or peach and gets into the coffee seed.Flavor is an accessible entry point for specialness.However, I don’t like talking about flavor and coffee too much. I don’t think coffee flav

Today's episode is very special because it was picked by the Making Coffee Podcast Patrons.
