In brief
A microlot is a small batch of coffee that a farm or exporter keeps separate instead of mixing it into a larger lot. It might come from one plot of land, one variety, one day's picking or one processing method. Keeping it apart preserves whatever makes it taste different.
Green coffee buyer Nordic Approach defines it as a lot "separated from the main harvest or processing batch to preserve its unique characteristics." It adds that microlots typically get extra attention at every stage.
The catch is that the word has no fixed meaning. Perfect Daily Grind found that traders, producers and roasters each use it differently.

How small is a microlot?
There is no standard size. Perfect Daily Grind quotes one Brazilian producer, O'Coffee Brazilian Estates, which treats micro lots as "up to 40 60-kilo bags" with cupping scores of 87 to 89 points. That is one company's rule, not an industry one.
Another expert quoted by Perfect Daily Grind suggests naming the size outright, such as a "100 bag micro lot" or a "10 bag micro lot." That alone shows how wide the range can be.
Is a microlot the same as single origin?
No. A microlot is one kind of single-origin coffee, but most single-origin coffee is not a microlot. Wikipedia notes that single origin can describe one farm, several farms in a country, or a whole country's production.
| Label | What it usually means |
|---|---|
| Single origin | From one known place, which may be a whole country |
| Single farm or estate | From one farm |
| Microlot | From one plot, variety, harvest or process, kept separate |
| Nano lot | Like a microlot, but smaller still |
The definitions in this table follow Perfect Daily Grind's 2018 guide. O'Coffee describes its nano lots as one or two 60-kilo bags, usually scoring 90 or more.
Does "microlot" mean the coffee is better?
Not by itself. Perfect Daily Grind quotes a trader who says some sellers call any unblended lot a micro lot because it is "pure," but that "it's not indicative of quality." Some roasters also split a larger purchase into smaller lots and sell each as a distinct coffee.
The term means more when the roaster backs it up. Look for the farm or producer name, the varietal, the processing method and the harvest. Wikipedia notes that no universal body enforces coffee labeling, so these details do the work the word cannot.
Why do microlots cost more?
Because small batches cost more to keep separate. Perfect Daily Grind explains that harvesting and processing on a small scale raises costs, so the sale price has to rise to cover them. For that reason, it says, micro lots are normally only coffees of excellent quality.
Nordic Approach adds that microlots are often sold as direct trade, and occasionally at auction. Traceable lots let a roaster tell you who grew the coffee and how. Nordic Approach says that traceability is part of what makes the coffee more valuable to consumers.
How should you brew a microlot coffee?
The same way you would brew any coffee of that roast level, with a little more care. A microlot does not need special equipment. What it does reward is a recipe you can repeat, so you can taste what makes it different.
If yours is roasted light, the advice on light roast applies: a finer grind and hotter water. With only a small bag, you have fewer chances to dial in. Weighing your dose with the brew calculator and starting from a known setting in the grind converter saves beans. For a step-by-step approach, see how to dial in pour-over coffee.
