If a guest wants to limit caffeine, start with a clearly labelled decaffeinated cold brew rather than assuming ordinary cold brew or diluted concentrate will suit them; decaf can still contain some caffeine. An unsweetened concentrate lets guests adjust taste and add their own milk, while a ready-to-drink latte avoids mixing but calls for a closer look at its ingredients and caffeine label.
Choose around what your guests will drink, rather than assuming everyone at an afternoon tea wants the same strength or style of coffee.
Keep a clearly labelled decaffeinated option separate from ordinary cold brew. NHS Lancashire Teaching Hospitals notes that decaf tea or coffee can still contain very low levels of caffeine, depending on how it was produced.
A concentrate lets guests have coffee black or add their preferred milk. Tesco Finest gives a starting recipe of 100ml concentrate and 100ml cold water; check the instructions for the bottle you buy.
A ready-to-drink latte simplifies serving, but check the current ingredient list against each guest’s requirements. Dairy and oat versions have different ingredients, and plant-based wording alone does not settle other allergen questions.
Settle the caffeine choice first, then choose between adjustable servings and drinks that can be poured straight from the pack.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine | Look for an explicit decaf label if caffeine avoidance matters. For other drinks, check any stated caffeine amount and its per-100ml or per-serving basis; adding water changes concentration, not the caffeine already poured. | I want a decaf option available for guests who ask for one, without assuming every cold brew is low in caffeine. |
| Serving style | Check whether the drink is ready to pour or needs dilution. Tesco Finest specifies 100ml concentrate with 100ml cold water; use the directions for your chosen product. | Several guests may want different-tasting drinks, or I may prefer to pour chilled lattes without measuring each glass. |
| Ingredients | Read the current ingredient and allergen information for milk, oat, wheat and soya where relevant. Do not use a vegan or dairy-free label as a substitute for checking other restrictions. | Before serving, I need to know which guests can have the particular latte or black coffee I bought. |
| Flavour and sugars | Distinguish unsweetened black coffee from flavoured oat drinks and dairy lattes. Check the ingredient list and nutrition label; no added sugar and zero sugars are different statements. | With cakes on the table, I would like guests to have a choice between plain coffee and a flavoured latte. |
| Storage | Check chilling instructions and the directions for use after opening, particularly if preparing drinks ahead of time. Follow the instructions on each pack rather than applying one product’s timeframe to another. | I may open a larger bottle before guests arrive and want to know how to keep and serve what remains. |
Brewing style does not tell you whether a drink is decaffeinated. M&S labels its Plant Kitchen chilled cold-brew oat latte at 34.6mg caffeine per 100ml.
Offer an explicitly decaffeinated option when requested, and check the current caffeine label on other drinks. Decaf does not necessarily mean caffeine-free.
Oat drinks can contain ingredients that matter for other restrictions. M&S states that its chilled oat latte is unsuitable for coeliacs and people with wheat or soya allergy.
Check the current ingredient and allergen information against each guest’s requirements before pouring.
Concentrates have product-specific preparation directions: Tesco Finest specifies equal amounts of concentrate and water, while Tesco describes Grind’s concentrate as espresso-strength and gives a 62ml pour in its directions.
Measure the first glass using the chosen pack’s instructions, then leave water and milk available for guests who want to adjust the taste.
A flavoured oat latte and an unsweetened black coffee offer different tastes alongside cakes and sandwiches. Dairy lattes can also contain added sugar.
If preferences vary, offer a plain unsweetened option as well as the latte, and let guests choose.
These examples illustrate the formats to compare; check the current pack for the particular drink you plan to serve.
Sainsbury’s lists a 250ml decaffeinated cold-brew oat latte with caramel flavour.
Its unsweetened cold-brew concentrate offers a black-coffee starting point that guests can dilute or combine with milk.
Its cold-brew range includes a dairy Classic Latte and a chilled oat latte.
Tesco lists a Grind cold-brew concentrate; Waitrose also lists a Grind instant coffee that can be mixed with cold water.
A Coffee Friend UK listing describes a ready-to-drink black cold brew made with coffee and filtered water.
This coffee liquid is an option for guests who want a cold brew diluted to taste rather than a ready-to-drink latte. Check its caffeine information before choosing it for anyone who asks for decaf.

The pouch format allows a drink to be mixed with water to taste instead of serving a pre-mixed latte. The product title states zero sugar and zero fat. Check the preparation directions and caffeine information on the current pack; dilution does not establish that a serving is suitable for someone avoiding caffeine.
No. The brewing method alone does not establish caffeine content: M&S labels its Plant Kitchen chilled cold-brew oat latte at 34.6mg per 100ml. Check the current label for the drink and serving you plan to offer.
Choose a drink explicitly labelled decaffeinated rather than treating a diluted concentrate as decaf. Sainsbury’s lists the Nolo decaf cold-brew oat latte as one such format; NHS Lancashire Teaching Hospitals notes that decaf coffee can still contain very low levels of caffeine.
Yes, if you choose a concentrate and follow its preparation directions. Tesco Finest specifies 100ml concentrate with 100ml cold water as a starting glass; adding more water changes the taste concentration, not the amount of caffeine in the concentrate already poured.
Read the current ingredient and allergen information for the exact drink. M&S Classic Latte contains semi-skimmed milk, while M&S states that its chilled oat latte is unsuitable for coeliacs and people with wheat or soya allergy; Sainsbury’s Nolo decaf latte contains oat.
Follow the instructions on that product’s pack rather than assuming all bottles keep for the same length of time. Tesco’s directions for Grind cold-brew concentrate say to refrigerate it after opening and consume it within seven days.
