For a street party, do not assume an ordinary coffee bag can replace a cold-brew pyramid bag: the Waitrose and Taylors bags described by their retailers call for hot water. Choose a cold-brew concentrate if you can provide water and mix drinks, or a ready-to-drink cold brew if you want to avoid dilution. Check the exact drink’s chilling instructions, ingredients and caffeine warnings before serving.
If guests will help themselves to cold coffee, decide whether you have space to dilute concentrate or would rather serve drinks that need no mixing. Check serving instructions rather than assuming a coffee bag works in cold water.
A dairy-free label does not answer every allergy question. Marks & Spencer labels its Plant Kitchen cold-brew oat latte vegan and dairy-free, but also unsuitable for coeliacs and people with soya or wheat allergy. Check the current pack against guests’ requirements.
Make caffeinated drinks easy to identify and provide a caffeine-free choice. Marks & Spencer labels its chilled oat cold brew high in caffeine and not recommended for children or pregnant or breast-feeding women.
Start with the preparation instructions, then work out portions and how you will keep drinks chilled at the party.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation method | Look for explicit cold-water preparation or a ready-to-drink cold brew. Waitrose & Partners instructs customers to brew its Colombian coffee bags in just-off-the-boil water for three minutes. | I want to serve cold coffee without discovering on the day that the bags require a kettle. |
| Portions and setup | Tesco Groceries instructs customers to mix 100 ml of its Finest concentrate with 100 ml of cold water. At that ratio, a 500 ml bottle makes five 200 ml drinks; allow for water, cups and mixing. Marks & Spencer lists its Classic Latte as a 250 ml ready-to-drink option. | How many guests can I serve, and do I have room for a mixing station? |
| Chilled storage | Read the storage instructions for the exact drink. Marks & Spencer specifies 0°C to +5°C refrigeration for its chilled cold-brew oat latte; Tesco says to refrigerate its concentrate after opening. | I need a way to keep the selected drinks at their stated storage temperature during the event. |
| Ingredients and caffeine | Check the current ingredient and allergy information, plus any caffeine warning. Marks & Spencer lists semi-skimmed milk in its Classic Latte; its oat latte carries separate allergy and high-caffeine warnings. | Guests need to be able to identify drinks that do not fit their dietary requirements, and I want a caffeine-free choice available. |
Waitrose and Taylors specify hot-water brewing for their listed coffee bags. Those instructions do not establish either cold-brew use or a pyramid-bag format.
Check the preparation directions for the exact bag before planning a cold-water serving station.
Tesco’s stated 100 ml concentrate to 100 ml water ratio means its 500 ml bottle makes five prepared 200 ml drinks, not five litres of coffee.
Calculate portions from the pack’s mixing directions and arrange the water, cups and stirring method before the party.
Marks & Spencer labels its chilled oat cold brew dairy-free, but also unsuitable for coeliacs and people with soya or wheat allergy.
Read the current pack and keep an alternative clearly separate when guests have different dietary requirements.
Marks & Spencer labels its chilled oat cold brew high in caffeine and not recommended for children or pregnant or breast-feeding women.
Keep the label available, identify caffeinated drinks and provide a caffeine-free choice.
These examples illustrate different preparation and serving formats; a brand’s inclusion does not mean its coffee bags are cold-brew pyramid bags.
Marks & Spencer lists ready-to-drink cold brews in both a dairy latte and a chilled oat latte format.
Tesco Groceries lists a cold-brew concentrate with cold-water mixing instructions, as well as separate hot-brew coffee-bag products.
Waitrose & Partners lists Fairtrade Colombian coffee bags made with arabica coffee.
This portioned coffee liquid is an option for a street-party mixing station, not a pyramid bag or a ready-to-drink bottle.

The individual pouches suit portioning at a mixing station, but this coffee liquid requires dilution rather than bag steeping. Check the current pack for preparation directions and caffeine information before serving.
Do not assume so. The Waitrose and Taylors coffee bags listed by their retailers specify hot-water brewing; check for explicit cold-water preparation instructions if cold brew is the drink you intend to serve.
At Tesco Groceries’ stated ratio of 100 ml concentrate to 100 ml cold water, its 500 ml bottle makes five prepared 200 ml drinks. Plan cups, water and any other additions separately.
Check the current pack’s storage, ingredient, allergy and caffeine information. Marks & Spencer specifies 0°C to +5°C refrigeration for its chilled oat cold brew and labels it unsuitable for coeliacs and people with soya or wheat allergy; it also carries a high-caffeine warning.
GOV.UK’s street-party guidance for England, published on 21 January 2025, says licences are not normally necessary for a residents’ or neighbours’ street party unless alcohol is sold. If you need a temporary road closure, it says to contact your council at least six weeks in advance; check the arrangements for your particular event with the council.
