Who is this for?

Organisers serving a large elevenses group

You need to establish how many finished drinks an order provides, then plan chilling and distribution. A count of packs or concentrate cartons is not the same as a count of servings.

Workplaces with a self-serve coffee station

Concentrate is an option when people can add water or milk on site. Use the instructions for the exact product to plan portions and opened-product storage.

Hosts accommodating different dietary needs

Check each drink’s label rather than relying on “cold brew”: Tesco Finest’s brown-sugar latte contains whole milk, while the M&S oat latte is described as dairy-free but is not suitable for coeliacs or people with a wheat allergy.

What should you check before ordering?

Decide whether drinks will be handed out ready to serve or prepared at the venue, then calculate the quantity from the exact pack and serving instructions.

Priority What to check Your needs
Pack count Ask whether “240” means pouches, cans, bottles or finished drinks. Confirm the number of units in the case and the serving size. I need an order that provides enough drinks for the people attending, not simply a pack labelled “240”.
Serving yield Tesco Groceries instructs users to mix 100ml of its Finest concentrate with 100ml cold water for one 200ml glass. Its 500ml bottle therefore makes five glasses at that ratio; Tesco lists up to eight servings from Grind’s 500ml carton using 62ml per serving. If drinks will be mixed on site, I need to count prepared servings and allow for the water or milk used with them.
Service method Check whether the drink is ready to serve or needs dilution, cups and mixing space. Tesco Groceries says to serve its 250ml brown-sugar cold-brew latte cold. For a quick handout, I would rather distribute individual drinks; with a staffed station, I can consider concentrate.
Ingredients and allergens Read the current label for each exact drink. Tesco Finest’s brown-sugar latte contains whole milk; M&S describes its oat latte as dairy-free but says it is not suitable for coeliacs or people with a wheat allergy. I need guests to be able to identify which drinks match their dietary requirements.
Storage and caffeine Check chilling and once-opened instructions for the chosen pack, plus its caffeine amount per prepared serving. Tesco Groceries directs users to refrigerate its Finest concentrate after opening and consume it within four weeks. I want a service plan that accounts for opened packs and lets people check the caffeine in the drink they choose.

Ordering mistakes to avoid

  • Taking “240” to mean 240 finished drinks

    The number could describe individual units, a pack measure or a claimed serving yield. Those meanings lead to different order quantities.

    Request a product specification stating the unit count, preparation method and finished-drink yield before placing a catering order.

  • Counting every 500ml concentrate carton alike

    Tesco Groceries gives a 100ml concentrate measure for each glass of its Finest product, while its Grind listing gives 62ml per serving. The two instructions do not produce the same serving count per carton.

    Calculate the cartons needed from the chosen product’s instructions, and plan the accompanying water, milk or ice separately.

  • Assuming cold brew is plain black coffee

    Cold-brew lattes can contain different ingredients: Tesco Finest’s brown-sugar version contains whole milk, and M&S says its dairy-free oat version is unsuitable for coeliacs or people with a wheat allergy.

    Check the current ingredient and allergen panel for every drink you intend to offer, and keep the options clearly identified during service.

  • Judging caffeine from the drink’s name

    Names such as “espresso-strength” do not give a caffeine quantity per finished serving. Caffeine from other food and drink also matters when considering total intake.

    Check the final product’s caffeine information or ask its manufacturer for the amount per prepared serving before using it in any intake calculation.

Brand and product-line references

Tesco Finest

Tesco Groceries lists a 500ml unsweetened cold-brew concentrate and a separate 250ml brown-sugar cold-brew latte.

  • The concentrate has a stated mixing ratio of 100ml concentrate to 100ml cold water for one glass.
  • The ready-to-drink latte contains whole milk and lists 11.0g sugars per 250ml can; check its label when planning alternatives.

M&S

M&S describes its 250ml oat latte cold brew as a dairy-free, ready-to-drink coffee.

  • The individual drink does not require a concentrate-mixing station.
  • Its label says it is not suitable for coeliacs or people with a wheat allergy.

Grind

Tesco Groceries lists Grind’s espresso-strength cold-brew concentrate in a 500ml carton for mixing with water or milk.

  • The listing states 62ml concentrate per serving and up to eight servings per carton.
  • It needs preparation on site; follow the carton’s own storage instructions after opening.

Joybuy cold-brew option

This portioned cold-brew coffee liquid is an option for an elevenses station where drinks can be prepared individually with water. Count the pouches needed for the planned service rather than treating one pack as a 240-drink case.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25ml × 10 pouches

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25ml × 10 pouches

The ten individually portioned pouches allow drinks to be prepared at a serving station, where water and mixing equipment will be needed. Check the pack’s preparation instructions and the number of packs required for your group; this pack is not a 240-unit case.

Questions about serving cold brew

What should a “box of 240” specify?

It should state what the 240 units are and how many finished drinks they provide. Before ordering for elevenses, ask the supplier for the case count, serving instructions, storage requirements and delivery details; a concentrate carton and an individual drink cannot be counted in the same way.

How many drinks does a 500ml concentrate make?

It depends on the exact concentrate. Tesco Groceries specifies 100ml of its Finest concentrate plus 100ml water for one 200ml glass, giving five glasses from 500ml; its Grind listing states up to eight servings from 500ml using 62ml concentrate per serving. Do not apply either ratio to another product.

Is an oat cold-brew latte suitable for every dairy-free guest?

No single “oat” label establishes suitability for every dietary requirement. M&S describes its oat latte cold brew as dairy-free, but its label says it is not suitable for coeliacs or people with a wheat allergy. Check the current label of the exact drink before serving it.

How can guests check the caffeine in a serving?

Use the caffeine amount for the exact prepared drink, if stated on its label, or ask the manufacturer. The European Food Safety Authority’s caffeine assessment considers intake from all dietary sources, so a product name alone cannot establish someone’s total intake.

Can opened concentrate be kept for another event?

Follow the storage and consume-within directions for that exact product. Tesco Groceries says to refrigerate its Finest concentrate after opening and consume it within four weeks; do not apply that period to a different concentrate.
