Choose a cold-brew concentrate if Christmas-party guests want different coffee intensities: Tesco Finest gives a starting serve of 100ml concentrate with 100ml cold water. A ready-to-drink M&S latte takes less mixing, its oat latte offers a dairy-free format, and Mr Black coffee liqueur belongs in a separately identified alcoholic serve. Bold flavour descriptions do not establish which drink contains the most caffeine.
A concentrate gives you a starting ratio while leaving room to vary the dilution in each glass. Tesco Groceries instructs buyers to mix 100ml of its Finest concentrate with 100ml cold water; you can then adjust the drink to taste.
A ready-to-drink latte avoids mixing each serving. The M&S Classic Latte is a 250ml option made with espresso and semi-skimmed milk, so check that a milk-based drink suits the guests you are serving.
The M&S Plant Kitchen oat latte is described as dairy-free and comes in a 750ml format. Keep any coffee liqueur, such as Mr Black, clearly separate from non-alcoholic drinks and reserve it for adult guests.
Decide whether you want to mix drinks or pour them ready-made, then check the ingredients and serving information for the people coming to your party.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour control | Check the concentrate’s dilution instructions and whether you can adjust the amount in each glass. Tesco Groceries specifies 100ml concentrate with 100ml cold water as a starting serve. | I want a bold coffee taste, but guests should be able to choose a lighter or stronger-tasting drink. |
| Serving effort | Distinguish a drink that needs dilution from a ready-to-drink latte. Check the pack size against how you plan to serve it. | When several people arrive at once, I would rather pour a chilled drink than mix every glass. |
| Milk and allergens | M&S describes its Classic Latte as containing semi-skimmed milk and its Plant Kitchen oat latte as dairy-free. Read the purchased pack’s ingredients and allergen declaration. | A milk-based latte will not work for everyone; I need a clearly identified alternative for guests avoiding dairy. |
| Caffeine | Check caffeine information and the stated serving size on the exact pack. Words such as “bold” and “extra-strong” describe a product, not a comparable caffeine measure. | I need to let guests judge their own caffeine intake rather than assume a stronger-tasting glass contains more caffeine. |
| Alcohol | Check whether the bottle is coffee or coffee liqueur. Mr Black is a liqueur, so identify it separately from non-alcoholic cold brew. | If I make an adult dessert drink, I still want a coffee option for guests who are not drinking alcohol. |
Flavour descriptions and concentrate ratios do not tell you how much caffeine a prepared serving contains. A smaller, less diluted glass may taste stronger without establishing how it compares with another product.
Use dilution to adjust taste, and check the exact pack’s caffeine and serving information when intake matters to a guest.
The M&S Classic Latte contains semi-skimmed milk, whereas M&S describes its Plant Kitchen oat latte as dairy-free. Similar-looking chilled coffees can therefore require different ingredient checks.
Identify the dairy-free choice clearly and read the current pack’s ingredients and allergen declaration before serving.
Mr Black is an alcoholic coffee liqueur, not a non-alcoholic ready-to-drink coffee. Guests need to know which drink contains alcohol.
Label an adult liqueur serve clearly, keep it separate and provide a non-alcoholic choice.
Waitrose’s cold-brew affogato recipe says its prepared cold brew can be chilled for up to two days. That recipe timing is not a storage instruction for a purchased concentrate or latte.
Follow the storage and use-by instructions for the exact drink or recipe you serve.
Its unsweetened 500ml cold-brew concentrate is a mixing option for serving drinks to different tastes.
Its chilled latte formats offer a choice between a 250ml milk-based drink and a 750ml dairy-free oat latte.
A black ready-to-drink cold-brew option for guests who do not want a latte.
An alcoholic coffee-liqueur option for a separately identified adult dessert drink.
A portioned cold-brew coffee liquid for hosts who want to mix individual drinks.
This portioned cold-brew coffee liquid suits a party where individual drinks can be mixed to taste rather than poured ready-made.

The individual pouches allow you to mix party drinks one at a time. The listing suggests one 25ml pouch with about 200ml water, adjustable to taste; each drink still needs preparing. “Extra-Strong” does not specify its caffeine content, so check the current pack if a guest needs that information.
Not necessarily. For a Christmas-party drink, “strong” may describe flavour or how much concentrate is used, neither of which establishes a caffeine ranking across products. Check caffeine information for the exact prepared serving if you need to compare intake.
Start with the concentrate maker’s preparation instructions, then adjust dilution to taste in individual glasses. Tesco Groceries specifies 100ml of its Finest concentrate with 100ml cold water as a starting serve; changing the ratio changes the drink’s concentration, so do not assume every guest wants the same amount.
Check the purchased pack’s ingredients and allergen declaration. M&S says its Classic Latte contains semi-skimmed milk and describes its Plant Kitchen oat latte as dairy-free; the word “cold brew” alone does not distinguish the two.
Yes, as a clearly identified alcoholic option for adults, not as a replacement for non-alcoholic cold brew. Mr Black is a coffee liqueur; keep a separate coffee choice available for guests avoiding alcohol.
Follow the instructions for the drink you are making. Waitrose & Partners says the prepared cold brew in its affogato recipe can be chilled for up to two days; that timing does not set the storage life of a purchased latte or concentrate, which should be kept according to its own label.
