For a New Year’s Eve party, choose individual ready-to-drink coffees if you want to hand out finished servings, or a concentrate if you plan to mix drinks to guests’ preferences. If ‘strong’ means a known caffeine amount, Sainsbury’s lists Jimmy’s Strong at 57mg per 100ml; M&S describes its cold brews as double-espresso drinks but does not give a comparable caffeine figure, so check each label rather than equating the terms. M&S describes its Oat Latte as dairy-free, but says it is not suitable for coeliacs or people with a wheat allergy.
Individual ready-to-drink coffees avoid measuring and mixing while guests arrive. Check how many portions you need, whether the drinks require chilling, and their milk ingredients. Sainsbury’s lists Jimmy’s Strong as a 250ml bottle with a declared caffeine amount.
An espresso concentrate lets guests choose additions and dilution, but each glass needs preparing. Tesco and Waitrose list 500ml Nescafé concentrates; follow the chosen pack’s directions before working out party quantities.
Look for an explicitly dairy-free drink rather than assuming cold brew contains no milk. M&S describes its Oat Latte Cold Brew as dairy-free, while also warning that it is not suitable for coeliacs or people with a wheat allergy.
Choose the serving format first, then check what the particular drink says about caffeine, ingredients and preparation.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine information | Look for caffeine in mg per 100ml and check the amount in the portion you will serve. Sainsbury’s lists Jimmy’s Strong at 57mg per 100ml; ‘strong’, ‘double espresso’ and ‘cold brew’ alone do not give comparable doses. | I want to know how much caffeine a full drink contains, rather than choosing by its name or coffee style. |
| Serving format | Compare finished individual drinks with concentrates that require mixing. Check the pack size and, for a concentrate, its preparation directions before calculating servings. | Am I handing out drinks as guests arrive, or setting up a station where they can choose how their coffee is mixed? |
| Ingredients and allergens | Read the current ingredient and suitability statements. Jimmy’s Strong and M&S Classic Latte contain semi-skimmed milk; M&S Oat Latte is described as dairy-free but is not suitable for coeliacs or people with a wheat allergy. | I need to offer a clearly labelled option that fits each guest’s dietary requirements. |
| Preparation and storage | Check whether the drink needs chilling, whether it is ready to serve, and what the pack says about storage after opening. For a concentrate, check the stated dilution before preparing a batch. | There may be little time to mix drinks during the party, or limited fridge space for opened bottles. |
Sainsbury’s gives Jimmy’s Strong a caffeine figure of 57mg per 100ml, while M&S describes its Classic and Oat Latte cold brews as double-espresso drinks without giving caffeine milligrams. Those descriptions cannot establish an equal dose.
If caffeine amount matters, compare figures in the same unit on the current packs and account for the full portion served.
Jimmy’s Strong and M&S Classic Latte contain semi-skimmed milk. M&S says its dairy-free Oat Latte is not suitable for coeliacs or people with a wheat allergy.
Keep the packaging available so guests can check ingredients and suitability for their own requirements.
Dilution and serving size change the amount of concentrate in each glass, so a 500ml bottle does not by itself tell you how many drinks to plan or their caffeine amounts.
Use the chosen bottle’s preparation and caffeine information when planning quantities, and allow time to mix the drinks.
A ready-to-drink option for individual chilled servings: Sainsbury’s lists Jimmy’s Strong Iced Coffee in a 250ml bottle.
Its Classic Latte and Oat Latte Cold Brew products are described by M&S as double-espresso drinks in 250ml formats.
Tesco and Waitrose list 500ml Espresso Concentrated iced-coffee products for preparing drinks rather than handing out finished individual servings.
Waitrose lists a 200ml Doubleshot Espresso Iced Coffee among its individual iced-coffee options.
These options cover a ready-to-drink espresso coffee and a portioned cold-brew coffee liquid for mixing. The espresso coffee is not identified as cold brew, and the two formats call for different preparation at a party.

For serving chilled coffee without mixing drinks, this 500ml espresso coffee is described as ready to drink; it is not identified as cold brew. Check the current pack’s caffeine declaration before using it to plan servings. Once opened, refrigerate and consume within the day as directed in the product information.

For drinks mixed to order, the 10 individual 25ml pouches provide portioned cold-brew coffee liquid rather than finished drinks. Follow the pack’s cold-water directions and adjust dilution to taste. Check its caffeine declaration before treating ‘Extra-Strong’ as a measure of caffeine per glass.
No. Look for a caffeine declaration on the pack if you need an amount to compare. Sainsbury’s lists Jimmy’s Strong at 57mg per 100ml, whereas M&S describes its cold brews as double-espresso drinks without giving caffeine milligrams; the names alone do not establish comparable doses.
Using Sainsbury’s listed figure of 57mg per 100ml, a full 250ml bottle contains 142.5mg by calculation. Check that the bottle you buy carries the same caffeine declaration before using that figure.
Not necessarily. M&S describes it as dairy-free but says it is not suitable for coeliacs or people with a wheat allergy. Check the current packaging against the guest’s specific requirements.
Check the bottle’s preparation directions, caffeine declaration, ingredients and storage instructions. Use its stated dilution and the portion you intend to pour when working out how many drinks to prepare; the 500ml pack size alone does not settle that question.
