How to Choose Coffee Beans

Note: This is an informational guide. Some links are affiliate links.

Standing in front of a wall of coffee bags, each with its own origin, processing method, tasting notes and roast profile, is one of the more paralysing experiences in modern grocery shopping. The bags assume knowledge you do not have. The roast descriptions are either absent or written in the language of a wine auction catalogue. This is a practical guide to making a good choice without knowing very much.

The One Thing That Matters More Than Anything Else: Freshness

Before origin, before roast level, before price — look for a roast date. Coffee is a perishable product. The CO2 that gives espresso its crema and filter coffee its complexity begins escaping from the bean the moment it’s roasted. Within four weeks of the roast date, a quality coffee is at its best. After eight weeks it begins to decline. After three months it is stale, regardless of how good it was when fresh.

Supermarket coffee almost never has a roast date — it has a “best before” date, which is not the same thing and tells you nothing useful. A bag with a roast date from a specialist roaster is almost always better than a famous supermarket brand, even at a similar price, simply because you know when it was roasted.

If there is no roast date, put it back.

Understanding the Information on the Bag

Origin

The country or region the coffee comes from. As a starting point:

• Ethiopia — fruity, floral, complex. The most interesting coffee-growing country in the world. Start here if you want something unusual.
• Colombia — balanced, chocolatey, approachable. The reliable choice. Works well for espresso and filter both.
• Brazil — nutty, chocolatey, low acid, heavy body. The most common espresso blend base. Comforting and consistent.
• Kenya — bright, berry-like, intense. For those who enjoy something more adventurous and don’t mind acidity.
• Indonesia (Sumatra) — earthy, heavy, low acid. For those who like very dark, intense coffee with no fruitiness whatsoever.

Processing Method

• Washed — clean, bright, the coffee’s natural characteristics shine clearly. Good starting point if you’re unsure what you like.
• Natural — fruity, wine-like, more intense. Divisive — some people love it, some find it too much. Try once before deciding.
• Honey — between the two. Sweeter than washed, less intense than natural. A safe middle ground.

Roast Level

Light roast means more of the original bean’s character — more acidity, more fruit, more complexity but less of the roasty, caramelised flavours. Dark roast means more of the roasting process’s character — chocolate, bitterness, body, less brightness. Medium roast balances both.

Contrary to popular belief: dark roast does not mean more caffeine. Light roasts actually retain slightly more caffeine. Dark roast means more roasted flavour, not more strength.

The Fastest Decision Framework

For espresso with milk (lattes, flat whites): Choose a medium roast Colombian or Brazilian. These origins have the body and sweetness to work well with milk without being overwhelmed by it.

For black espresso: Choose a light to medium roast Ethiopian or Colombian. The flavour complexity comes through clearly without milk masking it.

For filter or pour-over: Choose whatever sounds most interesting from a reputable roaster with a recent roast date. This is where lighter roasts and unusual origins shine.

For a safe, crowd-pleasing option: Medium roast Colombian from any roaster with a roast date within the past three weeks. Reliably good, works for everyone.

Where to Buy

In the UK, the best options for freshly roasted beans are specialist online roasters — Hasbean, Square Mile, Pact and Workshop all roast to order or close to it. Your local independent coffee shop often sells its own beans and these are almost always roasted recently. Supermarket beans are a last resort — convenient but typically stale by the time they reach the shelf.
