If a glass bottle is essential, choose a cold brew only when the retailer listing explicitly identifies the container as glass, then check the delivered item. Tesco's unsweetened concentrate is an option if you are happy to dilute your coffee; M&S's canned, milk-based cold brew is ready to drink, but neither listing establishes a glass-bottle choice.
If the container matters as much as the coffee, look for an explicit glass-bottle description and check what arrives. Tesco describes its concentrate as a bottle without identifying the material; M&S identifies its cold-brew latte as a can.
A concentrate suits you if you are willing to add water or another mixer rather than open a ready-to-drink coffee. Tesco instructs shoppers to combine 100ml of its unsweetened concentrate with 100ml of cold water.
M&S describes its 250ml cold-brew latte with semi-skimmed milk as ready to drink. Check its ingredients if milk or the drink's sweetness affects your choice, and bear in mind that it comes in a can.
Confirm the container and whether the coffee needs mixing before comparing ingredients or setting delivery preferences.
| Priority | What to check | Your needs |
|---|---|---|
| Container | Look for an explicit glass-bottle specification on the current listing. Check the delivered container and its condition; the word “bottle” does not identify its material. | I would rather confirm glass before ordering than assume a bottle-shaped pack meets my preference. |
| Drink format | Read the preparation directions and serving size. Tesco specifies 100ml of concentrate plus 100ml of cold water; M&S describes its 250ml latte as ready to drink. | Do I want coffee straight from the fridge, or am I happy to mix a concentrate? |
| Ingredients | Read the current ingredients and allergen label, particularly for a milk-based drink or a substitute. Check the delivered pack again before drinking. | Milk or a change in ingredients could affect which drink I choose. |
| Delivery | Review substitution settings before checkout. At handover, check that the drink and container match the order and that the pack is undamaged. | If the exact container or recipe matters, I want the chance to reject an unsuitable substitute. |
Tesco calls its cold-brew concentrate a bottle without specifying the material, while M&S identifies its latte container as a can.
Look for the word “glass” in the current product information and check the container on delivery; neither a product image nor “bottle” alone confirms it.
Tesco's concentrate has dilution instructions, unlike M&S's ready-to-drink cold-brew latte. That changes what you need to do before serving it.
Read the preparation directions before checkout if you expect to open and drink the coffee without mixing it.
A replacement could have a different container, ingredients or drink format. Tesco says it may offer substitutions when they are enabled.
Consider turning substitutions off for an exact packaging or ingredient requirement. Tesco says an unwanted substitute can be handed back to the driver or Click+Collect colleague for a refund.
A milk-based drink or substituted item may not have the ingredients you expected from a saved listing.
Check the current product information when ordering and read the delivered ingredients and allergen label before drinking.

The pouch format is an alternative to a glass-bottled drink for shoppers happy to prepare their coffee. The title specifies 10 × 25ml pouches. Confirm how to prepare it before ordering: the product information describes it as ready to drink but also gives directions to dilute a pouch with water.
Look for an explicit glass-bottle statement in the current product information, then check the delivered container. Tesco calls its concentrate a bottle without identifying the material, whereas M&S identifies its cold-brew latte container as a can.
Check the item at handover. Tesco tells customers to hand a damaged grocery item back to the delivery driver, who will process a refund; if you use another retailer, follow its damaged-item process.
Consider turning substitutions off when you need an exact container or ingredient list. Tesco says enabled substitutions may be offered and that an unwanted substitute can be returned to the driver or Click+Collect colleague for a refund; inspect any replacement before accepting it.
Use it when selecting a drink, but read the delivered label before drinking, especially if an item has been substituted. GOV.UK says prepacked food and drink must identify regulated allergens used as ingredients, including milk.
Follow the directions for the exact product. Tesco says to refrigerate its Finest 500ml cold-brew concentrate after opening and consume it within four weeks; that instruction does not establish storage times for other drinks.
