Who these beans suit
The useful starting point is what you mean by “strong”: a rich flavour, a stated roast intensity or a coffee that works with your brewer.
Regular espresso and bean-to-cup drinkers
A larger bag may suit you if you make coffee often and can keep the beans sealed after opening. Tesco describes its 1kg Italian Inspired Espresso beans as rich and intense, with dark-chocolate and spice notes.
Drinkers choosing by flavour intensity
If you want an explicit flavour cue, Lavazza labels Espresso Barista Intenso 9/10, while illy labels Intenso 7/9. Union describes Foundation as its darkest roast. These are product descriptions, not a shared caffeine scale.
Home brewers who grind their own beans
Whole beans let you set the grind for your equipment. M&S Food advises a fine grind for espresso and a coarser one for a cafetière; check the brewing guidance for the beans and machine you use.
What to check before choosing
Start with the flavour description and your brewing method, then decide which pack size fits how often you make coffee.
| Priority | What to check | Your needs |
| Flavour profile |
Read the exact roast and flavour description. Compare terms such as “rich and intense” or “dark roast”; brand intensity scales are not standardised across products. |
I want a pronounced espresso-style flavour, so a product described as intense or dark is a closer starting point than one described only as a rich medium roast. |
| Bean composition |
Check whether the beans are Arabica, Robusta or a disclosed blend. Waitrose & Partners notes that Robusta can contain up to twice the caffeine of Arabica, but composition does not give the caffeine content of a prepared cup. |
When I say “strong”, do I mean a forceful flavour or am I specifically asking about caffeine? A roast label cannot answer both questions. |
| Brewing method |
Check the product’s suggested methods and grind the beans for your equipment. M&S Food recommends fine grounds for espresso and coarser grounds for a cafetière; Union warns that an unsuitable grind can change extraction and taste. |
My beans need to work with the brewer I already use, whether that is an espresso machine, moka pot, filter brewer or cafetière. |
| Pack and storage |
Check the bag size and its storage instructions. Plan how you will reseal or store beans after opening, particularly with a 1kg pack. |
A large bag suits me only if I make coffee often enough to use it while its flavour is still good. |
Brand and product-line references
These examples describe particular beans and blends, rather than every coffee sold under each brand.
Lavazza
Espresso Barista Intenso is a 1kg Arabica-and-Robusta blend that Lavazza labels 9/10 for intensity and recommends for espresso or moka.
- Lavazza describes this blend as intense and full-bodied, with cocoa and woody notes.
- Its intensity rating describes this product’s flavour; it is not a caffeine measurement.
Illy
Illy Intenso 500g is a 100% Arabica option labelled 7/9 for intensity. Illy lists moka, filter, espresso and lungo among its brewing methods.
- The stated brewing methods give shoppers several ways to use the same beans.
- Do not compare its 7/9 rating directly with another brand’s differently scaled intensity number.
Taylors of Harrogate
Tesco describes Taylors Rich Italian 1kg as a 100% Arabica, rich medium roast with a roast rating of 4.
- Its stated flavour notes are dark chocolate and almonds.
- The medium-roast description is worth checking against your preference if you specifically want an extra-dark profile.
Union
Union describes Foundation as its darkest Italian-style roast and recommends brewing it as espresso.
- Union describes a heavy-bodied flavour intended to remain noticeable in milk drinks.
- That flavour description is Union’s own account of Foundation, not an independent comparison with other beans.
M&S
M&S Italian Style Coffee Beans come in a 454g bag and are described with a deep, rich aroma.
- M&S gives chocolate-and-nougat flavour notes for this product.
- If a numbered intensity rating matters to you, check the exact pack rather than assuming one from its Italian-style name.
Waitrose
Waitrose No.1 Italian Espresso is a 250g, full-bodied blend of 50% Fairtrade Arabica and 50% Fairtrade Robusta.
- Its disclosed blend composition helps distinguish it from a 100% Arabica option.
- The blend proportions do not establish the caffeine content of a prepared cup.

Questions about strong coffee beans
Does a darker roast always contain more caffeine?
No: a dark-roast or intensity label does not tell you how much caffeine is in a prepared cup. Waitrose & Partners explains that roast affects flavour intensity and that Robusta can contain up to twice the caffeine of Arabica. Check the blend information, but do not use it alone to calculate caffeine per cup.
Which grind should I use for strong whole beans?
Match the grind to your brewer rather than grinding every bean as finely as possible. M&S Food recommends a fine grind for espresso and a coarser one for a cafetière. Union notes that grinding too fine can produce a bitter taste, while grinding too coarse can produce a sour one.
How should I store a large bag after opening?
Reseal the beans or use an airtight container, and follow the instructions on the pack. Think about how often you make coffee before choosing a 1kg bag, since opened beans remain exposed to air each time you use them.
Can I put whole beans in a pod machine?
Not directly. Whole beans need grinding and brewing equipment that accepts them or their grounds; a pod machine needs capsules compatible with that machine. Check your brewer’s instructions before choosing whole beans.
Where should I check allergen information for packaged beans?
Check the product packaging and its ingredients list. GOV.UK guidance says that, for prepacked food and drink, any of the 14 regulated allergens present as ingredients must be clearly labelled in that list.
