Plan for 2 litres of finished drinks rather than looking only at the size of a cold-brew bottle. Concentrate lets you prepare drinks with different mixers but requires measuring and chilling them; ready-to-drink iced coffee takes less preparation but gives guests less choice over the finished drink. Check the exact pack for ingredients, caffeine and preparation instructions before serving.
Concentrate can be measured out as guests arrive. Tesco Groceries gives a 1:1 water-dilution method for its 500ml cold-brew concentrate; its Nescafé concentrate listing describes 16 prepared glasses using milk. Those are different recipes, so calculate quantities from the product you choose.
An unsweetened concentrate lets guests choose how their drinks are mixed instead of committing everyone to a ready-made latte. Keep the mixers identified separately and check each pack’s ingredients for guests with allergies.
Ready-to-drink bottles or individual servings avoid measuring concentrate at the party. Waitrose & Partners lists 750ml Starbucks iced coffees, while Marks & Spencer lists 250ml cold-brew servings; check whether the exact drink suits your guests before buying enough for the table.
Decide whether guests will mix their own drinks or pour a finished coffee, then count finished servings rather than packs alone.
| Priority | What to check | Your needs |
|---|---|---|
| Finished volume | Check the pack size, dilution method and stated servings. Tesco Groceries directs 100ml of its concentrate per 100ml cold water, making about 1 litre from a 500ml bottle before ice; two bottles make about 2 litres. Three 750ml ready-to-drink bottles provide 2.25 litres before ice. | I need enough drinks for the guests who actually want coffee, with some choice of serving size. A concentrate bottle’s volume is not its finished-drink volume. |
| Preparation | For concentrate, check the required mixer, measuring instructions, ice and serving containers. For ready-to-drink iced coffee, check whether the chosen flavour and ingredients suit the group. | If I cannot measure and mix drinks at the venue, bottles that are ready to pour would make the drinks table simpler. |
| Milk and allergens | Read the ingredients and allergen information on the exact pack. Marks & Spencer lists semi-skimmed milk in its Classic Latte; its dairy-free Oat Latte says it is not suitable for coeliacs or people with a wheat allergy. | Some guests may want coffee without dairy, while others may need to avoid particular ingredients. I need to identify each drink and mixer clearly. |
| Caffeine | Check the caffeine information for the prepared serving and the mixing ratio. Tesco Groceries lists 87mg per 180ml glass of Nescafé Unsweetened made with 30ml concentrate and 150ml semi-skimmed milk; Waitrose & Partners lists 94mg per prepared glass for Nescafé Iced Vanilla. | I want guests to recognise which drinks contain coffee and to have a non-caffeinated choice at the party. |
| Storage | Check chilling requirements and the instructions after opening for the exact product. Tesco Groceries says to refrigerate its Finest concentrate after opening and use it within four weeks; its Nescafé Unsweetened listing gives 14 days. | If I prepare drinks ahead of time, I need a way to keep the products as their packs instruct and avoid assuming every opened bottle has the same storage period. |
A 500ml bottle can make a different volume depending on its recipe. Tesco Groceries’ 1:1 method makes about 1 litre before ice from its 500ml concentrate; its Nescafé listing instead describes 16 glasses made with 30ml concentrate and 150ml semi-skimmed milk each.
Choose the drinks you intend to serve, then calculate the concentrate and mixer needed from that product’s directions.
Allow for chilled water or milk, ice and containers for mixing and serving.
Marks & Spencer’s Classic Latte contains semi-skimmed milk. Its Oat Latte is described as dairy-free but is not suitable for coeliacs or people with a wheat allergy.
Check the purchased packs, identify the drinks at the table and keep their ingredient information available to guests.
Caffeine depends on the product and prepared serving. Tesco Groceries lists 87mg per prepared glass for Nescafé Unsweetened, while Waitrose & Partners lists 94mg per prepared glass for Nescafé Iced Vanilla.
Mark coffee drinks clearly and provide a non-caffeinated alternative, particularly when guests include children.
A listing may identify a bottle size without giving the ingredient, caffeine or storage details needed for the drink you will serve. Those details also vary between products and flavours.
Before serving, check the exact pack’s volume, ingredients, allergen information, caffeine information, date and storage instructions.

The ten pouches offer a portioned alternative to a large bottle for a party drinks table. Check the pack’s mixing instructions and finished yield before calculating how many drinks they will make, and check its caffeine information before serving.
Two 500ml bottles make about 2 litres before ice using Tesco Groceries’ stated method of 100ml concentrate plus 100ml cold water per drink. That calculation is specific to this concentrate and dilution method.
Tesco Groceries lists 16 glasses when each uses 30ml concentrate and 150ml semi-skimmed milk, giving 2.88 litres of prepared drinks before ice. A different serving size or mixing method changes the finished quantity.
Read the exact pack and label coffee drinks clearly. Tesco Groceries lists 87mg caffeine per prepared 180ml glass for Nescafé Unsweetened, while Waitrose & Partners lists 94mg per prepared glass for Nescafé Iced Vanilla; provide a non-caffeinated option for guests who do not want coffee.
Not necessarily: Marks & Spencer says its 250ml Oat Latte Cold Brew Coffee is dairy-free but not suitable for people with a wheat allergy or for coeliacs. Check the ingredients and allergen information on the exact pack rather than relying on the drink’s name.
Follow the instructions on the bottle you buy. Tesco Groceries says to refrigerate its Finest concentrate after opening and consume it within four weeks; its Nescafé Unsweetened listing specifies refrigeration and consumption within 14 days. Neither period should be applied to a different drink.
