Choose an unsweetened concentrate if you want to decide how much water or milk goes into the coffee alongside biscuits. A black ready-to-drink cold brew avoids mixing, while a milk-based cold-brew latte suits someone who specifically wants a creamy, sweetened drink; check the ingredients and serving directions rather than assuming every cold coffee has the same balance.
If the biscuits are already sweet, an unsweetened concentrate lets you choose the dilution and whether to add milk or a plant-based alternative. Tesco Groceries lists water and optional milk additions for its Finest concentrate.
If you want a creamy cold coffee without mixing, M&S lists cold-brew lattes made with semi-skimmed milk and sugar. They are a different choice from an unsweetened or dairy-free drink.
If you prefer a ready-made drink without listed dairy or sugar, the Sandows cold brew described by Coffee Friend UK contains fresh coffee and filtered water. Check the current pack label and availability before buying.
Start with the drink you want beside the biscuits, then check how it is prepared and stored.
| Priority | What to check | Your needs |
|---|---|---|
| Sweetness and flavour | Read the ingredients and sugar information. Check whether flavouring or sweetened milk is already part of the drink. | I would rather let the biscuits provide the sweetness, so an unsweetened coffee appeals more than a sweetened latte. |
| Milk and allergens | Check for milk in the ingredients and allergen statement. With a concentrate, check which liquids the preparation directions allow. | I want to choose my own milk alternative, or avoid a drink that already contains dairy. |
| Preparation | Distinguish ready-to-drink cans from concentrates and dissolvable coffee. Read the stated serving and dilution directions before comparing formats. | For a drink straight from the pack, I would choose ready to drink; for a cup I can mix myself, preparation is worth the extra step. |
| Caffeine | Look for caffeine per stated serving and check the serving size. Consider tea and other caffeinated drinks as well as the cold coffee. | If I am having tea too, I want to know how much caffeine is in the portion of coffee I plan to make. |
| Storage | Check whether the pack needs refrigeration after opening and its stated use-by period once opened. Follow the instructions for that particular product. | I may only make an occasional cold coffee, so I want a pack size I can use within its opened-product instructions. |
A ready-to-drink latte may already contain milk and sugar. Marks & Spencer lists both in its Classic Latte, whereas Tesco Groceries describes its Finest concentrate as unsweetened.
Check the ingredients, sugar information and allergen statement before deciding which drink belongs alongside your biscuits.
A concentrate needs dilution, while a ready-to-drink can does not. Tesco Groceries directs buyers to mix 100 ml of its Finest concentrate with 100 ml of cold water.
Use the preparation directions and pack size to work out how many drinks a product makes before comparing it with a ready-made option.
Storage periods differ: Tesco Groceries says to refrigerate its Finest concentrate after opening and consume it within four weeks; NESCAFÉ GB says to refrigerate its unsweetened Espresso Concentrated product and use it within 14 days.
Follow the instructions on the product you buy and consider whether you will finish the pack in that period.
A cold coffee served at tea time is not necessarily the only caffeinated drink that day. Food Standards Scotland and the Food Standards Agency advise considering caffeine from coffee, tea and other sources together.
Check the coffee’s caffeine information per serving where available, and account for the portion you actually prepare alongside your other caffeinated drinks.
These examples illustrate differences in format and ingredients; a retailer reference does not mean every item is its own-label product.
Tesco Groceries lists an unsweetened cold-brew concentrate intended for mixing at home.
Marks & Spencer lists ready-to-drink Classic and Caramel cold-brew lattes.
NESCAFÉ Espresso Concentrated is a mix-at-home coffee base, rather than a bottled ready-to-drink cold brew.
Coffee Friend UK describes a 200 ml ready-to-drink black cold brew containing fresh coffee and filtered water.
Sainsbury's iced-coffee category provides a retailer reference for comparing coffee formats, not an identified own-label cold brew.
These are mix-at-home cold-coffee options for making an individual drink with biscuits, rather than ready-to-drink black coffees or milk-based lattes.

The individual pouches are a mix-at-home choice when you want to prepare one cold coffee alongside biscuits. Check the pack’s preparation directions and caffeine per serving if you are also drinking tea; if the extraction method matters to you, confirm it on the product information rather than relying on the cold-brew wording alone.

This is a flavoured, mix-at-home option rather than a plain coffee-only drink. Its directions describe preparing a single sachet with cold water; check the pack’s sugar and caffeine information for the portion you make if either affects your choice alongside biscuits.
No. Cold brew refers to coffee extracted using cold water, while an iced coffee may be brewed hot and then chilled. If the brewing method matters, check the product description: a cold drink may instead be made from espresso concentrate or another coffee base.
Follow that product’s label. Tesco Groceries says to refrigerate its Finest concentrate and consume it within four weeks of opening; NESCAFÉ GB gives 14 days after opening for its unsweetened Espresso Concentrated product. Neither period should be applied to a different pack.
Check caffeine for the coffee serving you intend to make and consider your tea and other caffeinated drinks too. NESCAFÉ GB states approximately 87 mg caffeine per 30 ml serving of its unsweetened Espresso Concentrated product; that figure does not describe other cold coffees.
Read the current ingredients and allergen label. M&S Classic Latte lists semi-skimmed milk, whereas Tesco Groceries lists its Finest unsweetened concentrate as suitable for vegans and gives water or a milk alternative as preparation options.
