What the terms mean
Single Origin is used for coffee with a shared origin. How narrowly this is defined can vary: country, region, cooperative, farm or specific lot. So ask if precision matters to you. The term alone guarantees neither a single farm nor a single variety.
A blend is a mixture of different coffees. It may be designed for a particular flavour profile or use. A blend is not automatically a hiding place for poor beans. Equally, a single origin does not automatically make a coffee better than a carefully composed blend.
Why coffees are blended
A roastery can combine several components to bring together body, flavour direction and performance in milk. It can also aim for a desired profile across changing harvests. Components may therefore change while the product name stays the same. Good communication explains these aims without promising complete uniformity from a natural product.
In its training, PROBAT distinguishes, among other things, blending before and after roasting. As a buyer, what matters most is how the blend is intended to taste and be prepared. The technical method alone does not establish a reliable ranking.
When a single origin is interesting
If you want to explore differences between regions, plants or processing methods, a more precisely identified lot can help. It offers a more concrete reference point for questions and comparisons. You need not turn it into a competition where the smallest lot automatically wins.
A Single Origin can work as espresso, filter coffee or a milk drink, depending on the roast and recipe. The category does not ban milk or sugar. Use the bean the way you enjoy it, and if you are curious, try a small sip on its own too.
A fair taste test
Compare a blend and a single origin intended for similar use. Putting a very dark espresso blend against a light filter coffee tells you little about the terms themselves. Dial in both sensibly and record your impressions before using the label as an argument.
Ask yourself: which cup would I like to drink again in the morning? Which is interesting as a small sample? The answers can differ. An uncomplicated everyday coffee need not provide a sensory adventure every day.
How to shop more purposefully
When buying, describe your brewing method, usual amount of milk and the flavour direction you want. Add whether you prefer a consistent everyday profile or deliberately want variety. These details help with choosing both a blend and a single origin. Then ask about the specific composition rather than inferring flavour from the category alone.
For a favourite blend, note its name and purchase date. For an individual lot, harvest or lot details are also useful if provided. If the product tastes different later, first check your recipe and the information. Agricultural products can change; the key question is whether that change is transparent and suits you.
