For around 2 litres of cold brew on curry night, two 500ml bottles of Tesco Finest concentrate make 2 litres when diluted with water as Tesco directs. Making cold brew from grounds is another option if you can prepare and filter it ahead of time; espresso concentrate is quicker to mix, but it is not cold brew.
If you want around 2 litres ready for curry night, compare the amount of finished coffee rather than the container size. Tesco Finest’s stated dilution makes a batch from two concentrate bottles; RAVE Coffee’s grounds offer a make-ahead route.
An unsweetened concentrate lets you offer milk or other additions separately. Tesco Finest is labelled unsweetened, while Coffee Friend describes its 200ml Sandows cold brew as sugar-free and dairy-free.
Check each drink rather than assuming cold coffees have the same ingredients. M&S lists semi-skimmed milk and sugar in its Classic Latte and marks its Oat Latte as unsuitable for coeliacs or people with a wheat allergy.
Start with the finished volume and whether cold brew itself matters, then check ingredients, portions and preparation time.
| Priority | What to check | Your needs |
|---|---|---|
| Finished volume | Tesco directs a 1:1 mix of its 500ml concentrate and water: two bottles make 2 litres. RAVE Coffee states that its 300g pack makes approximately 3 litres across three batches; check its batch instructions for the amount you plan to make. | I need enough prepared coffee for a group, not just a container that looks large on the shelf. |
| Coffee format | Check whether the product is labelled cold brew or espresso concentrate. Tesco Finest is sold as cold-brew concentrate; Nescafé’s iced-coffee product is espresso concentrate. | If I specifically want cold brew, another type of chilled coffee will not answer the same request. |
| Ingredients | Read the exact product label for milk, sugar and allergy warnings. M&S lists milk and sugar in its Classic Latte and marks its Oat Latte as unsuitable for coeliacs or people with a wheat allergy. | Guests may want different additions, so I would rather check the coffee and offer those separately. |
| Caffeine per portion | Nescafé GB states approximately 87mg caffeine per standard 30ml concentrate serving. Keep track of how many servings go into a jug or individual glass. | When drinks are mixed for a group, I want to know what counts as one serving. |
| Preparation and storage | RAVE Coffee advises allowing 12–24 hours for steeping and filtering. Tesco says to refrigerate its concentrate after opening and consume it within four weeks. | If curry night is soon, I need a preparation method that fits the time available. |
Nescafé’s iced-coffee concentrate is an espresso product, whereas Tesco Finest is sold as cold-brew concentrate. Bottle size alone does not tell you which coffee style you are buying.
If cold brew matters to your guests, check the exact product description before choosing an iced-coffee alternative.
A ready-to-drink serving and a concentrate bottle represent different amounts of finished coffee. Tesco’s stated 1:1 dilution turns two 500ml concentrate bottles into 2 litres.
Work out the finished amount using the preparation directions before deciding how many containers to buy.
M&S marks its Oat Latte Cold Brew Coffee as unsuitable for coeliacs and people with a wheat allergy. An oat-based name does not settle those suitability questions.
Check the current label for each guest’s requirements and keep separately offered additions clearly identified.
Nescafé GB states approximately 87mg caffeine per standard 30ml concentrate serving. A shared jug makes it less obvious how much concentrate went into each glass.
Follow the product’s serving directions and tell guests which coffee you have used.
These examples show how formats differ; a brand name alone does not establish the ingredients or yield of every product in its range.
Its 500ml Unsweetened Cold Brew Coffee Concentrate is an option for mixing a black batch with water.
Its 500ml Espresso Concentrated Iced Classic Unsweetened is an espresso-concentrate route to iced coffee.
Its Cold Brew Ground Coffee Nº. 9 is a make-ahead option for brewing a larger batch.
Its Classic Latte and Oat Latte Cold Brew Coffees are 250ml individual drinks, rather than a group-size bottle.
Coffee Friend lists Sandows as a 200ml ready-to-drink black cold brew.
This portioned coffee-liquid option may suit guests mixing individual cold drinks for curry night. Check its prepared yield and extraction method if you need around 2 litres of cold brew specifically.

The individual pouches offer a way to mix cold coffee separately for curry-night guests. The product is listed as zero sugar and zero fat; confirm its finished yield and cold-brew extraction method if either is essential to your plan.
Check the exact current listing before planning around a single bottle. The cited Tesco iced-coffee category includes a 750ml ready-to-drink format, while the M&S cold-brew lattes are 250ml; Tesco Finest’s 500ml product is a concentrate that must be diluted.
Tesco directs you to add 100ml cold water to 100ml concentrate. At that ratio, each 500ml bottle makes 1 litre, so two make 2 litres; Tesco says to refrigerate the concentrate after opening and consume it within four weeks.
No assumption about wider suitability should be made from the oat name: M&S marks this product as unsuitable for coeliacs and people with a wheat allergy. Check the current label against the guest’s particular requirements before serving it.
Nescafé GB states approximately 87mg caffeine in a standard 30ml concentrate serving. Its iced-latte directions pair that amount with 150ml semi-skimmed milk.
Allow for RAVE Coffee’s stated 12–24 hours of steeping, as well as filtering before guests arrive. Its 300g pack is stated to make approximately 3 litres across three batches, so follow the batch instructions for the quantity you intend to serve.
