Microlot is a term you see on specialty coffee bags alongside a high price tag. It signals something specific about how the coffee was produced and selected — but it is also used loosely enough that it is worth understanding what it actually means before paying a premium for it.
A microlot is a small, separately tracked batch of coffee from a specific and tightly defined source — often a single farm, a single field within a farm, a single processing lot, or a single varietal. The key is separation and traceability: the microlot is kept distinct from the farm's other production throughout picking, processing and export. This allows the flavour characteristics of that specific batch to be preserved and communicated clearly.
Most coffee farms produce many different lots of varying quality. Traditionally these were blended together at the mill or cooperative level, with the variation averaging out into a consistent but undistinguished product. The specialty movement created demand for the best lots to be identified and kept separate. When a farm's top-quality cherries — perhaps picked from the highest-altitude block, or from a specific variety — are processed and sold as a distinct lot, everyone from farmer to buyer to roaster can identify and price it accordingly.
A genuine microlot comes with specific information: farm name, farm section or field, harvest date, processing method, variety, altitude and often the name of the farmer or producer. This level of detail is how you distinguish a real microlot from a bag that just uses the word for marketing. If the bag says "microlot" but lists only the country, no farm, no processing detail and no harvest date, it is a marketing term rather than a verifiable claim.
Microlots cost more for two legitimate reasons: the labour of sorting and separating quality lots is real, and the competition for outstanding lots among specialty buyers drives prices up. At their best, microlots are genuinely different — more complex, more unusual, more clearly expressive of a place and season than a generic regional lot. At their worst, they are undistinguished coffees wearing a premium label. The safest approach: buy from roasters who publish specific farm and lot information rather than just using the word microlot.
