Shoppers who want a cold coffee straight away
A prepared coffee drink avoids a brewing step. Check whether it is cold brew or another type of coffee drink, and read the ingredients if additions such as oat or milk matter to you.
Who each format suits
Start with the drink you want, then decide whether you want to make it now or prepare it for later.
Shoppers planning to brew coffee at home
A dedicated cold-brew coffee bag is worth considering if you can prepare and store several servings. Chamberlain Coffee describes its oversized cold-brew bag as making four cups, so it serves a different purpose from an immediate single drink.
Shoppers who want a cold-water bag for a bottle
A cold-water pyramid bag may be convenient, but check what is inside. The Lipton Citrus Mint bag listed by Sainsbury's is green tea, not coffee.
What to check before choosing
For a first shop, settle the coffee-or-tea question before comparing preparation and portion sizes. Bag shape alone does not tell you what drink it makes.
| Priority | What to check | Your needs |
|---|---|---|
| Drink type | Read the product name and ingredients for coffee or tea. Check whether “cold brew” describes the coffee itself, rather than assuming a cold-water bag contains coffee. | I want coffee, so a tea pyramid bag will not meet that need even if it brews in cold water. |
| Preparation | Check whether the drink is prepared, needs diluting or must be brewed. Follow the instructions for the exact bag rather than transferring cold-water directions from a tea product to a coffee bag. | If I want a drink on the way home, I need a format I can use straight away; if I have time to brew, I can consider a bag. |
| Servings | Compare the pack's stated drink size or yield. M&S lists its Oat Latte Cold Brew Coffee as 250 ml; Chamberlain Coffee says each of its oversized cold-brew bags makes four cups. | One drink today and several servings prepared at home call for different formats. |
| Ingredients | Read the current ingredients and allergen information, particularly for prepared oat or milk coffee drinks. M&S states that its Oat Latte Cold Brew Coffee is not suitable for people with coeliac disease or a wheat allergy. | When an ingredient affects what I can buy, I need to check the exact pack rather than rely on the words “cold coffee”. |
Common mistakes to avoid
-
Buying cold-water tea when you meant to buy coffee
The Lipton Citrus Mint pyramid bags listed by Sainsbury's make green tea. Their cold-water instructions do not make them cold-brew coffee bags.
Look for coffee in the product name and ingredients before choosing a bag for a coffee drink.
-
Choosing a batch bag for a drink you want now
Chamberlain Coffee says each of its oversized cold-brew coffee bags makes four cups. It is a format for preparing several servings, not a prepared individual drink.
Choose a prepared drink for immediate use; consider a batch bag when you have a suitable container, a way to chill the coffee and time to make it.
-
Assuming prepared cold coffees have the same ingredients
M&S states that its Oat Latte Cold Brew Coffee is not suitable for people with coeliac disease or a wheat allergy. That warning concerns this product, not every cold coffee.
Read the current pack's ingredients and allergen information, especially when comparing oat, milk and flavoured drinks.
Brand examples to compare
These examples illustrate different drink and bag formats; the brand name alone does not establish that a product is a cold-water coffee pyramid bag.
M&S
M&S lists both a prepared Oat Latte Cold Brew Coffee and House Blend Coffee Bags.
- The oat coffee is a 250 ml prepared drink; the House Blend is sold as coffee bags containing ground arabica coffee.
- The coffee-bag listing does not describe a cold-water pyramid format. Check the oat drink's current pack for ingredients and suitability.
Waitrose
Waitrose lists its Fairtrade Colombian and Italian Style Coffee Bags among its one-cup coffee products.
- This is a route to consider when you want an individual coffee-bag serving.
- Check the chosen pack's preparation directions before buying it for cold-water brewing.
Chamberlain Coffee
Chamberlain Coffee offers an oversized bag specifically described as a cold-brew coffee product.
- The brand says each Organic Cold Brew Elephant Large Coffee Bag makes four cups.
- Its batch format is different from a small pyramid bag or a prepared drink for immediate use.
Lipton
Lipton's Citrus Mint pyramid bags listed by Sainsbury's are an example of a cold-water tea format.
- The directions specify at least 500 ml of cold water and a five-minute infusion.
- The bags contain green tea with citrus and mint flavouring, not coffee.
Joybuy coffee and coffee-bag options
These options cover portioned coffee concentrate, prepared coffee drinks and one-cup coffee bags. Choose by preparation method: a drink that can be chilled or mixed with cold water is not necessarily coffee brewed cold, and a coffee bag needs its own preparation instructions.

Starbucks Doubleshot Espresso Iced Coffee, 12 × 200 ml
A prepared iced espresso coffee in individual 200 ml portions, rather than a bag for brewing. It is not identified as cold brew; check the pack's ingredients, allergen information and storage instructions.

Cooling Hydration Nescafe Regular Coffee, 250 ml
A prepared 250 ml coffee drink to consider when you do not want to brew a bag. It is not identified as cold brew; read the current pack's ingredients and allergen information before choosing it.

Taylors of Harrogate Rich Italian Coffee Bags, 75 g
Individually portioned coffee bags for making a cup, rather than a prepared cold drink. Check the pack's brewing directions if you intend to use cold water; the bag format alone does not establish suitability for cold brew.
Questions about coffee and cold-water bags
Are cold-water pyramid bags the same as cold-brew coffee bags?
No: bag shape and cold-water directions do not tell you whether the contents are coffee. The Lipton Citrus Mint pyramid bags listed by Sainsbury's contain green tea, whereas Chamberlain Coffee describes its oversized bags as coffee for cold brew. Check the name and ingredients of the bag you intend to buy.
What can I choose if I want cold coffee straight away?
Choose a prepared coffee drink if you do not want to brew or mix one. M&S lists a 250 ml Oat Latte Cold Brew Coffee; check its current ingredients and suitability information before buying. An iced coffee may also be ready to drink without necessarily being cold brew.
How do I prepare a cold-water pyramid tea bag?
Follow the directions for the particular tea. Sainsbury's listing for Lipton Citrus Mint pyramid bags specifies at least 500 ml of cold water and a five-minute infusion. Those instructions do not apply to coffee bags generally.
Where should I check allergens on a pre-packed drink?
Read the ingredients on the current pack. GOV.UK states that pre-packed food labels must show the food name and an ingredients list, with the 14 allergens required to be declared emphasised within that list. Check the exact product rather than assuming different cold coffees have the same ingredients.
