Who each format suits

The useful distinction for an afternoon tea is whether you need cold drinks immediately, can brew ahead or want a separate hot-coffee option.

Hosts setting up a cold coffee station

Concentrate can be diluted as guests arrive, leaving you to offer water, milk or a plant-based alternative separately. Follow the chosen product’s mixing instructions when planning portions.

Hosts preparing the day before

Cold-brew bags suit a make-ahead batch if you have time to steep them. Chamberlain Coffee’s method leaves an XL bag in water overnight, so it does not suit a last-minute start.

Hosts offering hot coffee to a larger group

An 80-bag box provides individually portioned coffee for a hot-drink station. Staples UK describes the Taylors Rich Italian 80-pack as a hot-water product, not cold brew.

What to check before buying

Start with the drink you intend to serve, then check its preparation time, stated portions and ingredients against your guest list.

Priority What to check Your needs
Cold brew or hot coffee Read the brewing directions, not just the bag count. Staples UK specifies hot water for its Taylors 80-pack; Waitrose describes a four-minute hot brew for the 10-bag format. I want cold brew at the party, so a box of hot coffee bags would only cover a separate hot-drink station.
Number of drinks Tesco Groceries directs 100ml concentrate plus 100ml cold water per glass: its 500ml bottle makes about five 200ml glasses at that ratio. Grind states up to eight servings from its 500ml carton when mixed 1:1; these are different serving methods. How many glasses and possible refills should I allow for? I need to calculate using the serving directions on the product I choose.
Preparation time Concentrate is mixed when serving. Chamberlain Coffee instructs an overnight steep for its XL cold-brew bag, while Marks & Spencer describes its 250ml cold-brew latte as ready to drink from the fridge. If I cannot start brewing the night before, I need a format that is ready to mix or serve when guests arrive.
Ingredients and choice Check the current label and keep additions separate. Tesco describes its unsweetened concentrate as suitable for vegans; the M&S Classic Latte Cold Brew Coffee contains semi-skimmed milk and sugar. Some guests may want black coffee or avoid dairy. I would not make a milk-containing latte the only cold option.
Caffeine information Check the serving size and caffeine information for the exact product, particularly if offering refills. Provide a drink without caffeine as another choice. I want guests to know what coffee is being served and to have an alternative if they are avoiding caffeine.

Mistakes to avoid

  • Assuming 80 coffee bags mean 80 cold brews

    Staples UK’s Taylors Rich Italian 80-pack calls for hot-water preparation. It can cover hot coffee service, but not a cold-brew station.

    If cold brew is the aim, check that the product specifies a cold-steeping method, or choose a clearly described cold-brew concentrate or ready-to-drink product.

  • Counting concentrate volume as finished drinks

    At Tesco’s stated 100ml concentrate plus 100ml water per glass, a 500ml bottle makes about five 200ml glasses. Grind’s stated yield of up to eight servings uses its own serving guidance, so the two counts should not be treated as interchangeable.

    Plan from the instructions for the product you buy, allowing for the portions and refills you expect to serve.

  • Offering only a dairy latte

    M&S Classic Latte Cold Brew Coffee contains semi-skimmed milk. Guests avoiding dairy cannot use it as their cold coffee option.

    Check labels and offer a separate black or dairy-free choice; label milk and plant-based additions clearly.

  • Overlooking caffeine when offering refills

    Concentrate portions can differ between products and between drinks poured by a host. The coffee base and serving directions matter when guests are deciding whether to have another.

    Keep the product information available and offer water and a drink without caffeine alongside the coffee.

Brands and retailers to know

These examples illustrate different drink formats; a retailer listing or brand range does not mean every product in it is cold brew.

Tesco finest

Tesco’s 500ml unsweetened cold-brew concentrate is a mix-to-order option for a cold coffee station.

  • Tesco specifies 100ml concentrate with 100ml cold water per glass and labels the product suitable for vegans.
  • It requires dilution and serving supplies; it is not an 80-bag product.

M&S Food

Its 250ml Classic Latte Cold Brew Coffee is a chilled, ready-to-drink individual serving.

  • Marks & Spencer describes it as ready to enjoy straight from the fridge.
  • It contains semi-skimmed milk and sugar, so it does not cover guests seeking a dairy-free or unsweetened black coffee.

Waitrose

Waitrose lists Taylors Rich Italian coffee bags in a 10-count hot-coffee format.

  • Its listing gives a four-minute brewing instruction for individually prepared hot coffee.
  • That listing does not describe cold-brew bags or an 80-pack.

Grind

Grind’s 500ml cold-brew concentrate offers a stated dilution method for planning drinks.

  • Grind states that mixing it 1:1 makes up to eight servings.
  • The number served changes if you pour different portion sizes or use a different dilution.

Taylors of Harrogate

Its Rich Italian coffee bags provide a hot-coffee alternative when individual portions matter.

  • Staples UK lists an individually wrapped pack of 80.
  • The 80-pack uses hot water; it should not be counted as cold brew.

Sainsbury's

Sainsbury's lists a Nescafé unsweetened iced espresso concentrate as another cold-drink format.

  • Its listing states 16 glasses using 30ml concentrate and 150ml semi-skimmed milk per glass.
  • The product is described as an iced coffee concentrate, not as cold brew; the stated serving method also includes milk.

Joybuy option for cold coffee service

This single-serve coffee liquid is mixed with cold water for drinks at the party. If coffee made by cold steeping is essential, check its preparation method before choosing it.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, ten 25ml pouches

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25ml × 10 pouches

For individual cold drinks, the preparation directions say to mix each 25ml pouch with about 200ml cold water. The pack contains ten pouches, not 80 bags. Check the preparation method if cold-steeped coffee is essential, and check the label for caffeine information before serving guests who need it.

Frequently asked questions

Does an 80-pack of coffee bags count as cold brew?

No—not the Taylors Rich Italian 80-pack listed by Staples UK. Its instructions call for hot water, so it is a hot-coffee alternative rather than 80 cold-brew servings.

How many glasses does Tesco cold-brew concentrate make?

At Tesco Groceries’ stated ratio of 100ml concentrate to 100ml cold water, a 500ml bottle makes about five 200ml glasses. Plan separately for refills or different pours.

Can I start cold-brew bags on the afternoon of the party?

Not if you are following Chamberlain Coffee’s XL-bag method: it calls for one bag in four cups of water, left overnight. Start the day before or choose a ready-to-mix or ready-to-drink format.

What should I offer guests avoiding dairy?

Check current product labels and provide a separate option. Tesco describes its unsweetened concentrate as suitable for vegans, whereas M&S Classic Latte Cold Brew Coffee contains semi-skimmed milk; keep any milk additions clearly labelled.

What if guests want to avoid caffeine?

Offer a drink without caffeine and make the coffee product information available. Check the exact product’s caffeine information and serving directions rather than assuming that all cold coffee portions are alike.
