Who is each format for?

Hosts making several drinks

A concentrate lets you prepare drinks to different tastes rather than serving everyone the same canned recipe. Tesco Groceries lists its 500 ml Nescafé concentrate as making 16 glasses when prepared as directed.

Guests who want a chilled latte

A ready-to-drink latte avoids mixing at the table, but its milk and other ingredients are already set. M&S lists a Classic Latte containing semi-skimmed milk and an Oat Latte it describes as dairy-free.

People choosing coffee after a late meal

If you would rather avoid another standard caffeinated serving, consider a decaffeinated drink. Sainsbury's lists a Nolo decaf cold-brew oat latte; check the can if you need its specific caffeine information.

What should you check before buying?

Start with how you will serve the coffee, then compare the prepared serving—not just the name on the front of the pack.

Priority What to check Your needs
Adjustable strength Check whether the drink needs mixing, its stated dilution and how many servings the pack makes. Tesco Groceries gives 30 ml concentrate plus 150 ml milk for one Nescafé glass and lists 16 glasses per bottle. I want to make a bolder drink for one guest and a lighter one for another, rather than open identical cans for everyone.
Caffeine Look for a caffeine amount tied to the serving you will drink. Tesco Groceries states 87 mg for its specified prepared Nescafé serving; that figure does not describe a larger pour. Check a decaf product's label for its own details. For a late dinner, I want to know what this drink adds to the caffeine I have already had.
Milk and allergens Read the current pack ingredients and allergen declaration. M&S lists semi-skimmed milk in its Classic Latte and describes its Oat Latte as dairy-free, but says the oat version is unsuitable for people with coeliac disease or a wheat allergy. A creamy drink sounds appealing, but I need its particular milk, oat and allergen information before serving it.
Ingredients and sugars Compare the ingredients and nutrition per 100 ml or 100 g on the relevant packs. Check whether a concentrate's prepared-drink figures include the milk you plan to use; M&S lists sugar among its Classic Latte ingredients. I would rather choose the coffee base and mixer myself than assume every product labelled cold brew has the same recipe.
Storage after opening Check refrigeration instructions and the opened-pack period. Tesco Groceries says to use its Nescafé concentrate within 14 days of opening; Sainsbury's lists three days for opened Rodd's Original Latte and 24 hours for opened Nolo decaf latte. If only a few guests want coffee, I need a pack size and opening period that fit how I will use the remainder.

What can catch you out?

  • Reading “strong” as a caffeine figure

    Names such as “strong”, “double shot” and “cold brew” do not give comparable caffeine amounts. Tesco Groceries states 87 mg for one specified prepared Nescafé serving, while M&S describes its lattes using a double shot of espresso.

    Compare caffeine only when the figures refer to the servings you would actually drink. Do not apply a prepared-serving figure to a different dilution.

  • Using a latte as though it were black concentrate

    A concentrate needs mixing; the M&S Classic Latte is a ready-to-drink recipe containing semi-skimmed milk and sugar. They offer different amounts of control over the finished drink.

    Choose the format before comparing flavours: decide whether you want to add your own water or milk, or serve a pre-mixed latte.

  • Assuming dairy-free means suitable for every guest

    M&S describes its Oat Latte as dairy-free but says it is unsuitable for people with coeliac disease or a wheat allergy.

    Check the current pack's allergen declaration for the particular guest; do not use a dairy-free description as a substitute for that check.

  • Forgetting the opened-pack period

    Storage instructions differ: Tesco Groceries gives its opened Nescafé concentrate 14 days under refrigeration, while Sainsbury's gives opened Rodd's Original Latte three days and Nolo decaf latte 24 hours.

    Check the pack when you open it, and choose a format you are likely to finish within its stated period.

Common questions

How can I make a more pronounced coffee drink?

A concentrate lets you adjust the amount of liquid you add, following the pack directions as your starting point. Tesco Groceries specifies 30 ml of its Nescafé concentrate with 150 ml milk and ice; its 87 mg caffeine figure applies to that prepared serving, not a stronger pour.

Is concentrate or a can easier for several guests?

Choose concentrate if guests want drinks mixed differently; Tesco Groceries says its 500 ml Nescafé bottle makes 16 glasses when prepared as directed. A ready-to-drink latte saves mixing but has a fixed recipe, so check its ingredients against your guests' needs.

Is an oat latte suitable for everyone avoiding dairy?

No. M&S describes its Oat Latte as dairy-free but says it is unsuitable for people with coeliac disease or a wheat allergy. Check the current pack's allergen declaration before serving it.

What should I check when serving coffee late?

Check the caffeine amount for the serving you plan to drink and consider other caffeine consumed that day. If you want to avoid another standard caffeinated coffee, Sainsbury's lists a decaffeinated Nolo cold-brew oat latte; check its pack for product-specific details.
