Choose concentrate if you need to mix several drinks and can bring water or milk, ice and cups: Grind says its 500 ml carton makes 1 litre, or up to eight servings, when diluted 1:1. For drinks you can serve without mixing, M&S lists both a semi-skimmed-milk latte and a dairy-free oat latte; a black coffee option gives guests another milk-base choice. Check each pack’s ingredients and allergen information, and keep any coffee liqueur separate from non-alcoholic drinks.
Concentrate lets you prepare drinks from one carton, provided you bring the mixer and serving supplies. Grind states that its 500 ml concentrate makes 1 litre, or up to eight servings, at a 1:1 dilution with water or milk.
Separate dairy and dairy-free choices make the options clearer to guests. M&S describes its Classic Latte Cold Brew as containing semi-skimmed milk and its Oat Latte Cold Brew as dairy-free and made with oat milk. Guests with allergies still need to check the relevant pack.
Cold-brew coffee liqueur belongs in a separate, clearly identified adult drinks area, not among the general coffee refreshments. Waitrose lists Jamaican rum in Tia Maria Cold Brew Coffee Liqueur; GOV.UK states that selling alcohol to someone under 18 is against the law.
Start with the number of drinks you plan to serve, then decide whether guests need ready-poured bottles or a coffee base they can mix. Check milk bases and labels before settling on the final selection.
| Priority | What to check | Your needs |
|---|---|---|
| Servings | Compare pack size with the stated dilution and serving instructions. Grind says its 500 ml concentrate makes 1 litre, or up to eight servings, when mixed 1:1 with water or milk. | I’m serving a group and need to work out how many drinks each pack will make. |
| Serving method | Check whether the drink is ready to pour or needs a mixer, cups and preparation space. Ready-to-drink lattes have a set milk base; concentrate is mixed before serving. | Will I have time and space to prepare drinks, or do I need bottles guests can take straight from the chilled selection? |
| Milk and allergens | Read the current ingredients and precautionary-allergen information on each pack. M&S describes its Classic Latte as containing semi-skimmed milk and its Oat Latte as dairy-free with oat milk; dairy-free does not establish suitability for every allergy. | I’d like guests to see which drinks contain dairy and check the packaging for their own requirements. |
| Black coffee | Check whether a black option is ready to drink or must be diluted, and whether any milk or syrup will be added at the table. | Some guests may want coffee without a pre-mixed latte base, with mixers offered separately. |
| Caffeine and storage | Check the specific pack’s caffeine and storage information, including any instructions for serving after opening. | I need to make product information available to guests and keep the drinks as their packs instruct. |
| Alcohol status | Read the product category and ingredients: Waitrose lists Jamaican rum in Tia Maria Cold Brew Coffee Liqueur. Keep any liqueur distinct from non-alcoholic cold brew. | If children or other guests avoiding alcohol attend, the general coffee selection must not be confused with cocktail ingredients. |
Waitrose’s Tia Maria Cold Brew Coffee Liqueur contains Jamaican rum, so it is not an ordinary coffee refreshment for a mixed-age street party.
Check the category and ingredients before buying. If you offer cocktails, identify them clearly and keep them separate from non-alcoholic drinks.
Grind’s stated yield for its 500 ml carton depends on mixing the concentrate 1:1 with water or milk; it is not the volume available straight from the carton.
Plan the mixer alongside the concentrate and bring a way to measure and serve the drinks.
You may also need ice and cups at the serving table.
M&S describes its Oat Latte Cold Brew as dairy-free, but that claim does not answer every allergen question. The Food Standards Agency explains that precautionary allergen information communicates the possibility of unintended allergen presence.
Keep the packaging available so guests can check the current ingredients and precautionary-allergen statement for themselves.
Tesco cautions that reformulation can change a food product’s ingredients, nutrition and allergen information.
When the drinks arrive, check the physical packs against your serving plan, including their ingredients, allergen information and storage instructions.
These references illustrate different cold-brew formats and product categories; check the particular pack rather than assuming a whole retailer or brand range has the same ingredients.
Ready-to-drink latte cold brews for individual serving.
A grocery retailer listing own-label and branded cold-brew concentrates.

This portioned coffee liquid is an option for hosts who can mix drinks at the serving table. If the drink must be made by cold-brew extraction, confirm its preparation method before buying.

The ten separate pouches suit a serving table where drinks can be mixed individually. Water or another mixer is needed; confirm the brewing method if cold-brew extraction matters to your selection, as the listing also describes the coffee as instant soluble. Check the current pack for caffeine information.
Use the dilution stated for the particular concentrate. Grind says its 500 ml carton makes 1 litre of prepared cold brew, or up to eight servings, when mixed 1:1 with water or milk.
Offer both if you expect guests to want each milk base, or include an oat latte if you need a dairy-free latte-style choice. M&S describes its Classic Latte as containing semi-skimmed milk and its Oat Latte as dairy-free; check each current pack’s ingredients and precautionary-allergen information for guests with allergies.
No. Waitrose lists Jamaican rum in Tia Maria Cold Brew Coffee Liqueur, making it an alcoholic product rather than a general non-alcoholic coffee drink. Keep any cocktail offering clearly separate; GOV.UK states that selling alcohol to someone under 18 is against the law.
Check the physical product label before serving. Tesco cautions that reformulation can change ingredients, nutrition and allergen information, so an online listing should not be the final reference for a guest’s dietary requirements.
