Hosts mixing coffee for a group
A concentrate lets you prepare individual glasses with different amounts of water or milk. Tesco Finest directs a 1:1 mix with water, while Grind gives a 1:1 mix with water or milk.
Who each format suits
Guests who prefer black coffee
A ready-to-drink black option avoids both mixing and a milky latte. Coffee Friend describes Sandows cold brew as dairy-free and sugar-free; check the current pack when buying for a particular dietary need.
Guests choosing a dairy-free can
M&S describes its Oat Latte as dairy-free, but its listing also says the drink is unsuitable for coeliacs and people with a wheat allergy. Check the pack before serving it to a guest with either restriction.
What to check before choosing
Decide whether you want to mix drinks for the table or serve individual bottles and cans; then check what each product means by “strong”.
Unsweetened concentrate
Choose it when: you want to adjust the taste of each glass while serving several people.
Bear in mind: each drink needs mixing, and the opened bottle must be stored as its pack directs.
Ready-to-drink black cold brew
Choose it when: you want a cold black coffee without preparing individual mixes.
Bear in mind: it offers less control over the finished drink than a concentrate.
Milk or oat latte
Choose it when: individual, creamy drinks suit your guests better than black coffee.
Bear in mind: milk and oat recipes have different ingredient and allergen considerations; check each can.
| Priority | What to check | Your needs |
|---|---|---|
| Mixing and serving | Tesco Finest directs 100 ml concentrate plus 100 ml water; Grind directs 62 ml concentrate mixed with 62 ml water or milk. Check the number of finished glasses you plan to make. | I would like to vary how bold each guest’s coffee tastes, rather than serve identical cans. |
| Caffeine information | Grind states 101 mg caffeine per 62 ml concentrate serving. Coffee Friend lists 40.5 mg per 100 ml for Sandows; check the amount you would actually serve rather than comparing those differently sized quantities as a ranking. | If “strong” means caffeine to me, I want a declared amount and a clear serving size, not just the word on the front of a pack. |
| Ingredients and allergens | M&S Classic Latte lists semi-skimmed milk. M&S describes Oat Latte as dairy-free but unsuitable for coeliacs and people with a wheat allergy; check the current pack. | Someone at the table may need a dairy-free drink or need to avoid wheat, so the exact recipe matters. |
| Sweetness | Tesco lists 0 g sugars per 100 ml of its unsweetened concentrate. M&S lists 3.8 g sugars per 100 g of Classic Latte; note the different products and measurement bases. | With scones and jam on the table, I may prefer an unsweetened coffee to a prepared latte. |
| Opening and storage | Read the current pack for refrigeration and how soon to use the drink after opening. Check stock before relying on one product for a gathering. | I may open a bottle before guests arrive or have some left afterwards, so I need its storage instructions to fit my plans. |
Mistakes to avoid
-
Treating “strong” as a caffeine figure
Grind declares 101 mg caffeine per 62 ml concentrate serving, while Coffee Friend lists 40.5 mg per 100 ml for Sandows. Waitrose’s listing for Jimmy’s Iced Coffee Strong gives no caffeine amount, so its name does not establish a like-for-like comparison.
If caffeine quantity matters, check both the declared amount and the serving or volume it describes.
-
Planning to pour concentrate straight into glasses
Tesco Finest and Grind both give 1:1 mixing directions. Bottle volume alone does not tell you how many prepared glasses you will serve.
Plan the finished drinks using the pack’s directions, with water, ice and any optional milk ready for guests.
-
Assuming an oat latte suits every guest avoiding dairy
M&S Oat Latte is described as dairy-free but is marked unsuitable for coeliacs and people with a wheat allergy. M&S Classic Latte and Jimmy’s Iced Coffee Strong list semi-skimmed milk.
Check the current pack’s ingredients, allergens and precautionary statements before serving a guest with an allergy or intolerance.
Brands and retailer ranges to compare
These examples show how different concentrates, black coffees and lattes are described; check the exact product rather than assuming a characteristic applies across a brand.

Its 500 ml unsweetened cold-brew concentrate is an option for mixing individual black coffees.
- Tesco lists 100% Arabica coffee, 0 g sugars per 100 ml and a 1:1 preparation with water.

Grind
Grind’s cold-brew concentrate is described as espresso-strength and mixed with water or milk.
- Grind states 101 mg caffeine per 62 ml concentrate serving and directs a 1:1 mix.
- Tesco marked its Grind 500 ml listing out of stock when checked; confirm current stock before planning around it.

- Check the current pack for its ingredients and caffeine declaration when those details affect your choice.
Sainsbury’s
Its iced-coffee category offers a place to compare product formats rather than a single Sainsbury’s cold-brew recipe.
- The category lists Nescafé Iced Coffee Espresso Concentrated Unsweetened 500 ml among its options.
- Check that product’s own details for preparation, ingredients and caffeine information before comparing it with another drink.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25 ml × 10 pouches
Ten portioned pouches allow guests’ drinks to be mixed individually. The directions say to add about 200 ml water per pouch and adjust to taste; the pouches are not ready to drink as supplied. The name describes the coffee as zero sugar and extra-strong, but “extra-strong” does not specify its caffeine content.
Questions about serving cold brew
Which cold-brew format gives me control over each cream-tea serving?
A concentrate lets you change the finished drink by adjusting the mix. Tesco Finest directs 100 ml concentrate plus 100 ml water; Grind directs 62 ml concentrate mixed with 62 ml water or milk. Start with the directions on the product you buy and adjust the taste for each guest.
Can I serve a dairy-free cold brew?
Yes, provided the exact product suits the guest’s needs. Tesco lists its Finest concentrate as vegan, Coffee Friend describes Sandows as dairy-free, and M&S describes Oat Latte as dairy-free. M&S also marks that Oat Latte unsuitable for coeliacs and people with a wheat allergy, so check the current pack.
What should I check when serving guests with allergies?
Check the current pack’s ingredients, highlighted allergens and precautionary statements for each drink. M&S Classic Latte and Jimmy’s Iced Coffee Strong list semi-skimmed milk, while M&S Oat Latte carries coeliac and wheat-allergy warnings.
What does a caffeine figure mean for a guest who is pregnant?
The NHS advises no more than 200 mg caffeine a day during pregnancy. Grind states that a 62 ml serving of its concentrate contains 101 mg caffeine; that figure needs to be considered alongside caffeine from other food and drinks consumed that day.
