Plan for 80 finished drinks, rather than assuming a box of 80 coffee bags will make 80 cold brews. For 200ml drinks made to Tesco Finest’s stated recipe, 16 of its 500ml unsweetened concentrate bottles provide 80 servings; individually served cans avoid dilution but require one can per drink. A bulk tap format could simplify self-service, but Amazon.co.uk lists the Sandows 3L bag-in-box as unavailable, so check stock before planning around it.
The useful starting point is how guests will be served: from a jug, an individual can or a self-service tap.
Concentrate gives you a repeatable calculation when you can measure and mix drinks. Tesco Groceries instructs buyers to combine 100ml of its concentrate with 100ml of cold water, making five 200ml drinks from a 500ml bottle.
A ready-to-drink can avoids mixing at the BBQ. If each drink is one can, serving 80 drinks means handling 80 cans; check the ingredients before choosing one latte recipe for every guest.
An unsweetened black coffee base lets guests add milk or other extras separately. Tesco Finest’s concentrate is one such option; the Sandows black coffee bag-in-box has a tap format, but its Amazon.co.uk listing is marked unavailable.
Choose a serving size and count the finished drinks first. Then match the preparation and ingredients to the way you will serve them.
| Priority | What to check | Your needs |
|---|---|---|
| Drink yield | Use the pack’s preparation instructions and your chosen cup size. Tesco Groceries specifies 100ml concentrate plus 100ml cold water per drink: a 500ml bottle makes five 200ml drinks, so 16 bottles make 80 at that dilution. | I’m planning 80 finished drinks, not just counting the number of bags, bottles or boxes. |
| Serving set-up | Concentrate needs measuring and cold water. A ready-to-drink can needs no dilution; a 3L tap box needs a pour size and enough fridge space. Check stock before relying on the Sandows box listed as unavailable by Amazon.co.uk. | Would I rather mix drinks in jugs, hand out individual portions or let guests pour their own? |
| Ingredients | Read the current label for milk and other ingredients. Marks & Spencer describes semi-skimmed milk in its Classic Latte Cold Brew Coffee; keep additions separate if guests need to choose their own. | I’d like guests to be able to identify a milk-containing latte and choose a black coffee instead. |
| Guest information | Keep packaging available so guests can check ingredients and product-specific caffeine information. The NHS says its pregnancy caffeine limit counts all food and drink sources, not coffee alone. | Guests should be able to check what is in their drink rather than rely on a general assumption about cold brew. |
Conventional coffee bags are intended for brewed coffee; their bag count does not tell you the yield of a cold-brew concentrate, can or tap box.
Calculate finished drinks from the specific product’s instructions. At Tesco Finest’s stated dilution, allow one 500ml concentrate bottle for five 200ml drinks.
Marks & Spencer’s Classic Latte Cold Brew Coffee contains semi-skimmed milk, so it does not provide a dairy-free choice.
Check current labels and make the ingredients clear. If guests want different additions, serve a black coffee base with milk and other options separately.
Amazon.co.uk marks the Sandows 3L bag-in-box as unavailable. Its capacity and tap design alone cannot establish that it will be ready for the BBQ.
Check current stock, the product label, delivery timing and fridge space before using a bulk box as the centre of the serving plan.
Guests may need to identify milk in a latte or check caffeine information for the particular drink. The NHS advises a daily caffeine limit during pregnancy that includes all sources.
Keep each drink’s packaging accessible and identify milk-containing options clearly; do not assume every cold brew has the same caffeine content.
These examples illustrate different formats; they do not represent a single interchangeable range of 80-serving packs.
Its 500ml unsweetened cold-brew concentrate suits a plan based on measured, mixed drinks.
Its Classic Latte Cold Brew Coffee is an individually served alternative to mixing concentrate.
A 3L black cold-brew bag-in-box offers a different, tap-based serving format.
Its conventional coffee bags are relevant only if brewed coffee, cooled separately if desired, would also work for the event.
This Joybuy option is a portioned coffee liquid sold as cold brew. It is for mixing individual drinks, rather than serving straight from a can or a bulk tap box.

The ten-pouch pack offers individual portions to mix with cold water at the BBQ. At one pouch per drink, eight packs provide 80 pouch-based servings; supply the water separately. The product is sold as cold brew coffee liquid, but confirm its extraction method if that distinction matters to you, and check the current label for caffeine per pouch.
For 80 drinks of 200ml each, allow 16 of the 500ml bottles if you follow Tesco Groceries’ instruction to mix 100ml concentrate with 100ml cold water per drink. That gives five drinks per bottle; provide the water, ice and any optional additions separately.
No: a conventional coffee-bag count is not a cold-brew serving calculation. Marks & Spencer describes its House Blend bags as a brewed coffee option, while Waitrose & Partners lists conventional coffee bags in a 15-count pack. Follow the preparation instructions for the product you actually serve.
No. Marks & Spencer describes semi-skimmed milk in its Classic Latte Cold Brew Coffee. Keep its packaging available and offer a separately identified option without milk if guests need one.
Check caffeine information for the particular drink rather than assuming all cold brews have the same amount. The NHS says caffeine during pregnancy should not exceed 200mg a day from all food and drink sources, so an individual drink needs to be considered alongside everything else consumed that day.
