Choose strong-tasting beans by flavour and brewing method, not by assuming that a high intensity rating means more caffeine. An intense blend can suit an espresso or moka coffee during revision; for a later session, consider decaf if caffeine affects your sleep. Check the pack size before committing to a flavour you have not tried.
If you make coffee with an espresso machine, moka pot, bean-to-cup machine or cafetière, start with the flavour profile you enjoy and check the beans against your usual brewing method. An intensity rating describes the product’s taste, not its caffeine content per cup.
If you want coffee during an evening study session but find that caffeine affects your sleep, compare decaf whole beans with regular blends. The NHS notes that caffeine in coffee can make you feel more awake and affect how well you sleep.
If you have not settled on a roast or flavour, a smaller bag lets you try it with your usual equipment before buying a larger pack. Make sure you have a way to grind whole beans, whether separately or in your machine.
For revision coffee, decide when you will drink it and how you will brew it, then compare flavour descriptions and pack sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour and caffeine | Read roast and intensity descriptions for expected flavour. Check whether the beans are Arabica, Robusta or a blend if caffeine matters: Waitrose says Robusta can contain up to twice the caffeine of Arabica, but bean type does not give a prepared-cup amount. | I want a bold-tasting coffee without mistaking a dark-roast label for a caffeine measurement. |
| Brewing method | Check the named preparation methods and whether you can grind whole beans. Lavazza lists Espresso Barista Intenso for espresso and moka; illy lists Intenso for moka, filter, espresso and lungo. | The beans need to work with the coffee equipment I actually use while revising. |
| Time of day | Compare regular and decaf beans for later sessions. The NHS says caffeine can affect sleep; a strong flavour alone does not tell you whether a coffee is decaf. | For an evening cup, I would rather choose the coffee with my sleep plans in mind than rely on its roast name. |
| Pack size and storage | Compare the stated bag size before trying an unfamiliar flavour. Follow that product’s storage instructions after opening rather than assuming every pack has the same guidance. | If I am still finding a flavour I like, a smaller bag is less of a commitment than a 1 kg pack. |
You could end up with a darker-tasting coffee without knowing how much caffeine is in the cup. Waitrose explains roast strength in terms of flavour, body and acidity, while bean type is a separate caffeine consideration.
Choose an intensity for the taste you want. If caffeine intake matters, check any manufacturer disclosure and consider your other sources of caffeine too.
Coffee may make you feel more awake, but the NHS says caffeine can also affect sleep. A bold roast is not necessarily a suitable choice close to bedtime.
Consider when you will drink regular coffee during revision and whether decaf would suit a later cup.
Strong-tasting beans do not all taste alike, and a large pack is a greater commitment if the flavour or brewing method does not suit you.
Check the preparation guidance and try a smaller pack where available before moving to a larger bag.

These whole-bean options include a dark-flavour choice, another regular-coffee blend and two decaf choices for later revision. Compare each pack with your preferred brewing method before buying.

Consider these whole beans if a dark flavour appeals for a revision coffee. The 200 g pack is a smaller commitment than a 1 kg bag; check the brewing guidance for your equipment and do not use the flavour name as a caffeine measurement.

This 1 kg bag makes more sense once you know you want this blend regularly than when you are trying a flavour for the first time. If an extra-bold taste is the priority, check its roast and flavour description before choosing it.

These decaf whole beans are an option to consider for a later revision coffee. The 200 g bag lets you try the flavour in a smaller format; check the pack’s brewing guidance for your equipment.

Consider these decaffeinated whole beans if you want a coffee option for later study. At 500 g, the pack is a larger flavour commitment than a 200 g bag; check its preparation guidance if you use a particular brewer.
No: an intensity score describes a product’s flavour profile, not the caffeine in a prepared cup. Waitrose says roast strength affects flavour, body and acidity, while Robusta can contain up to twice the caffeine of Arabica. Check bean composition and any caffeine disclosure separately.
Lavazza lists Espresso Barista Intenso for both espresso and moka. illy lists its Intenso beans for those methods as well as filter and lungo; choose between them by the flavour and bean composition you prefer, not by comparing their intensity scores as caffeine amounts.
Decaf is an option if you want coffee later in the day while reducing caffeine exposure. The NHS says caffeine can affect sleep, so a dark or intense regular coffee is not automatically the better fit for an evening cup.
Not without knowing how much caffeine is in each prepared drink and what you consume from other sources. The European Food Safety Authority’s 2015 opinion says daily intake from all sources up to 400 mg does not raise safety concerns for adults in the general population, except pregnant women; it gives a separate figure of up to 200 mg per day for pregnant women. These are safety assessments, not targets or a number of cups.
Follow the instructions for the particular beans rather than applying one rule to every pack. For its Roast & Ritual Decaf beans, M&S specifies an airtight container for two weeks in the fridge or four weeks in the freezer after opening.
