For a measured caffeine dose, choose a drink that states milligrams per bottle: Tesco lists 150mg in a 250ml Grenade Killa Caffe Latte. If “strong” means coffee flavour with your gaming snacks, a concentrate lets you adjust dilution, while a ready-to-drink latte is simpler to serve; neither format nor a “double espresso” description establishes a comparable caffeine dose.
A stated amount per bottle makes it easier to count this drink alongside other caffeine consumed during the day. Tesco lists 150mg in a 250ml Grenade Killa Caffe Latte; the word “strong” alone cannot provide that figure.
A concentrate gives you control over how much water or milk to add. That may appeal if you prefer black coffee with savoury snacks but a milkier drink with sweet ones.
M&S lists an oat cold-brew latte, but says it is unsuitable for coeliacs or people with a wheat allergy. For a late session, Ocado lists a water-decaffeinated Nescafé iced-coffee concentrate; check the exact pack for ingredients and caffeine information.
Decide whether “strong” means a stated caffeine amount or a bolder-tasting drink, then check preparation, ingredients and storage for the way you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine amount | Look for milligrams per bottle or prepared serving. Tesco lists 150mg per 250ml Grenade Killa Caffe Latte; “strong” and “double espresso” do not give a comparable figure on their own. | I want to know how much caffeine is in the drink, rather than choosing by its name or flavour description. |
| Other caffeine | Count the stated amount alongside any other coffee, tea, energy drinks or caffeinated snacks you plan to have. For decaffeinated products, check the pack if a precise caffeine amount matters. | During a long session, I want to keep track of caffeine from more than one drink or snack. |
| Preparation | Check the suggested concentrate-to-water or concentrate-to-milk ratio. Tesco Finest specifies 100ml concentrate plus 100ml cold water; Tesco’s Grind listing specifies a 62ml serving mixed with water or milk. | I would rather adjust a drink to my taste than open a ready-mixed latte. |
| Snack pairing | Compare black, unsweetened concentrates with milk-based or oat lattes. Tesco lists 0g sugars per prepared 200ml glass of its Finest concentrate; ingredients and sugar figures depend on the exact latte. | With savoury snacks, I may prefer coffee without added sweetness. With sweet snacks, I might choose a milkier drink instead. |
| Ingredients and storage | Read the exact variant’s milk, oat and wheat information. Check its dilution instructions and how long an opened concentrate can be kept. | I need a drink that fits my ingredient requirements, and I may not finish a large concentrate bottle in one session. |
A flavour description or “double espresso” wording does not tell you the milligrams of caffeine in a finished drink. By contrast, Tesco states 150mg per 250ml bottle for Grenade Killa Caffe Latte.
If caffeine amount drives your choice, look for a figure per bottle or prepared serving rather than comparing product names.
A 150mg bottle contributes to the caffeine you consume alongside other drinks and caffeinated snacks during a session.
Check the amounts on everything you plan to have instead of treating the coffee as separate from the rest.
Serving instructions differ: Tesco Finest specifies 100ml concentrate plus 100ml water, while Grind specifies 62ml concentrate per serving.
Compare how you would prepare each drink and check the opened-pack storage instructions, especially if you only make one occasionally.
An opened bottle may go unused if its stated storage period does not fit how often you make a drink.

The single-serve pouches let you mix a cold coffee alongside snacks; the description suggests diluting one 25ml pouch with about 200ml water and adjusting to taste. It states 0g sugar per 100ml, but also calls the product instant soluble coffee. Check the pack if brewed cold brew or a stated caffeine amount is essential to your choice.
No: “strong” may describe flavour rather than a stated caffeine dose. Ocado describes Jimmy’s Iced Coffee Strong as having a deeper coffee flavour and a little extra caffeine than others in its range, but that wording does not give milligrams per drink. Check the label when the amount matters.
Use the amount stated for each drink or serving and include other caffeinated drinks and snacks you have. Tesco lists 150mg per 250ml Grenade Killa Caffe Latte bottle; a concentrate without a stated prepared-serving figure cannot be compared with that dose by dilution ratio alone.
An unsweetened black concentrate is an option if you want the coffee flavour distinct from crisps or other savoury snacks. Tesco Finest specifies a 1:1 mix of concentrate and cold water and lists 0g sugars per prepared 200ml glass; whether that pairing appeals is a matter of taste.
Yes. M&S describes its Oat Latte as dairy-free but says it is unsuitable for coeliacs and people with a wheat allergy. Check the allergen declaration on the exact variant rather than relying on “dairy-free” alone.
A decaffeinated iced-coffee concentrate is an alternative to choosing a regular cold brew because it tastes smooth. Ocado describes Nescafé Espresso Decaf Iced Concentrate as water-decaffeinated and suggests mixing 30ml concentrate with 150ml milk; check its pack if you need a precise caffeine figure or different mixing instructions.
