For 2 litres of black cold brew, two 500ml bottles of Tesco Finest concentrate make the required amount when each is mixed with an equal volume of cold water, following Tesco’s directions. If guests prefer a ready-to-pour latte-style drink, two 1-litre Arctic Coffee cartons listed by Sainsbury’s also total 2 litres, but that listing does not identify them as cold brew; check the exact drink’s ingredients before serving.
If guests want to add their own milk or sweetness, a concentrate can be mixed with water and served separately from the additions. Tesco’s directions make the prepared volume straightforward to calculate: two 500ml bottles make 2 litres at the stated dilution.
A ready-to-drink carton avoids mixing. Sainsbury’s lists 1-litre Arctic Coffee latte cartons, while Tesco and Waitrose list 750ml Starbucks iced coffees. These are latte-style or iced-coffee choices, not necessarily black cold brew.
Serving black coffee with additions on the side gives guests a choice. Tesco labels its concentrate suitable for vegans; M&S lists a dairy-free oat cold-brew latte but warns that it is unsuitable for coeliacs and people with a wheat allergy. Check the current pack for every drink you serve.
Choose when: You want 2 litres of black cold brew with milk or other additions served separately. Tesco directs an equal-volume mix of its concentrate and cold water.
Allow for: Two 500ml bottles, water and a jug are needed; it is not a single ready-to-pour bottle.
Choose when: Everyone wants a pre-mixed latte-style drink. Sainsbury’s lists 1-litre Arctic Coffee latte cartons, and Tesco and Waitrose list 750ml Starbucks iced coffees.
Bear in mind: An iced-coffee or latte listing does not by itself establish cold-brew extraction, and ingredients vary by variant.
Choose when: Separate portions matter more than pouring from one container. M&S lists 250ml cold-brew lattes, while Coffee Friend lists a 200ml Sandows ready-to-drink cold brew.
Allow for: Reaching 2 litres takes eight 250ml drinks or ten 200ml drinks, with more containers to handle.
| Priority | What to check | Your needs |
|---|---|---|
| Prepared volume | Check whether the label states pack volume or volume after dilution. Tesco directs 100ml of concentrate with 100ml of cold water; one 500ml bottle therefore makes 1 litre at that ratio. | I’m serving about 2 litres, so I need to count the drink I can pour, not just the concentrate in the bottles. |
| Coffee style | Check whether the exact product is cold brew, another iced coffee or a pre-mixed latte. Do not treat a larger latte carton as black cold brew on the basis of its size. | Some guests may want black coffee with their own additions; a pre-mixed latte would not give them that choice. |
| Ingredients | Read the current variant’s ingredient and suitability information. M&S Classic Latte Cold Brew contains semi-skimmed milk and sugar; M&S warns that its dairy-free Oat Latte Cold Brew is unsuitable for coeliacs and people with a wheat allergy. | If guests have different dietary requirements, I want to know what is in each drink before putting it out. |
| After opening | Follow the chosen pack’s storage instructions. Tesco says to refrigerate its concentrate after opening and consume it within four weeks; do not apply that period to other drinks. | There may be coffee left after the party, so I need to check how the opened product should be kept. |
A 500ml concentrate bottle is not necessarily 500ml of prepared drink. Tesco’s specified equal-volume dilution makes 1 litre from one bottle.
Calculate the served volume from the exact preparation directions. For Tesco Finest concentrate, mix two 500ml bottles with 1 litre of cold water to make 2 litres.
M&S Classic Latte Cold Brew contains milk, while its dairy-free Oat Latte Cold Brew carries a warning for coeliacs and people with a wheat allergy.
Read the current label for each variant. If you need to offer a choice, serve black coffee and suitable additions separately rather than relying on one pre-mixed latte.
Tesco lists Tia Maria Cold Brew Coffee Liqueur in its spirits range, and Waitrose describes Mr Black Cold Brew Coffee Liqueur as made with vodka. Neither is interchangeable with non-alcoholic party coffee.
Check the full product name and alcohol information before buying a drink found through a cold-brew search.
The 750ml iced coffees listed by Tesco and Waitrose and the 1-litre Arctic Coffee lattes listed by Sainsbury’s offer larger serving formats, but their listing names do not establish that they are cold brew.
If the brewing method matters, check the wording on the exact product page or pack rather than choosing by carton size alone.
Tesco lists a 500ml unsweetened cold-brew concentrate for mixing with water.
M&S lists 250ml Classic Latte and Oat Latte cold-brew drinks for individual servings.
Waitrose lists iced-coffee formats including a 500ml Nescafé concentrate and 750ml Starbucks cartons.
Sainsbury’s lists 1-litre Arctic Coffee lattes alongside smaller concentrates and multi-serve iced coffees.
Coffee Friend lists Sandows as a 200ml ready-to-drink cold brew.
These options cover mixable coffee pouches and individually bottled espresso iced coffee. Check the brewing method if cold-brew extraction is essential: a product named cold brew is not interchangeable with an espresso iced coffee.

The ten individual pouches offer a mixable option for a group, rather than a ready-to-pour bottle. The product directions suggest about 200ml of water per 25ml pouch, giving approximately 2.25 litres if all ten are prepared that way. The title calls it cold brew, but the description also calls it instant soluble; check the extraction method if that distinction matters.

Twelve ready-to-drink bottles total 2.4 litres for guests who want individual, milk-based iced coffees. This is espresso iced coffee, not black cold brew. The product description lists milk and sugar, calls for storage at 2–8°C and carries a caffeine warning; check the current pack before serving.
No. If you want exactly 2 litres of black cold brew, two 500ml bottles of Tesco Finest concentrate make that amount at Tesco’s stated equal-volume dilution. A single ready-to-drink 2-litre cold-brew bottle was not listed on the M&S, Waitrose, Tesco or Sainsbury’s pages considered here; check current listings if one bottle is essential to your plans.
Mix two 500ml bottles with 1 litre of cold water. Tesco directs 100ml of concentrate per 100ml of cold water, so each bottle makes 1 litre at that ratio. Measure the drink before adding ice if you need to keep track of the prepared volume.
Yes, if guests want a pre-mixed latte-style drink rather than black cold brew. Check the exact product: M&S Classic Latte Cold Brew contains semi-skimmed milk and sugar, while a carton described only as iced coffee is not necessarily cold brew.
Read the current label of each exact variant before serving. Tesco labels its cold-brew concentrate suitable for vegans, whereas M&S Classic Latte Cold Brew contains semi-skimmed milk. M&S describes its Oat Latte Cold Brew as dairy-free but states that it is unsuitable for coeliacs and people with a wheat allergy.
