Producer Toolkit: Storage, Pt 2 - Why plastics are not all equal

October 26, 2026 · 29 min

Show notes

This episode explores the black box between coffee leaving the farm and the roaster's warehouse, and how quality can be ruined. Wrapping the coffee in any old plastic bag won't do. We get geeky looking at how hermetic bags like GrainPro actually work.

Part of The Coffee Producer Toolkit, a series made in collaboration with Lucia Solis, it will help you understand coffee farming better than most professionals you'll meet at a trade show.

Each episode takes one part of the farming business — agronomy, processing, fermentation, storage, quality, sales — and lays out what the best farms are actually doing.
