Lot numbers are one of the tools that make single-origin coffee possible. Single-origin coffee is all about traceability or knowing exactly where your coffee comes from. When a coffee is certified as single-origin, you’re able to tell where it was grown. The lot number allows you to know exactly which farm it was grown on. But this information isn’t just about taste. It’s also about securing economic freedom for coffee farmers, ensuring they are paid fairly for their craft.
