Allergens & Dietary Information

Costa publishes a full allergen guide covering all 14 legally-declarable allergens, plus vegan and vegetarian suitability, across its café menu. We're working through this item by item and will only publish a figure once it's been checked against that official guide — nothing here is guessed.

If you have a food allergy or intolerance, please don't rely on this site alone. Ask a member of staff for Costa's current official allergen guide before you order, every time — recipes and suppliers can change without notice, and this page cannot replace an in-store check.

Caffeine Content

Caffeine content scales with the number of espresso shots in a drink, not the drink name itself — a Latte and a Cappuccino with the same shot count have the same caffeine. Figures below are taken directly from Costa's official Store Allergen Guide (27 Aug – 21 Oct 2026 edition).

Shots Coffee Type Caffeine
1 shot Espresso (single) 100 mg
2 shots Standard drinks (Latte, Cappuccino, Flat White, Americano, etc.) 200 mg
3 shots Triple-shot drinks 325 mg
4 shots Quad-shot drinks 400 mg

This guide refreshes roughly every 8 weeks, so figures may be updated in later editions — check back here for the latest.

Where To Check Right Now

The most reliable source for allergen information today is Costa's own official allergen guide, available in-store or on Costa's own website. Our category pages also show calories where we've confirmed them, with allergen columns being added as they're verified.

⚠ Important Allergen Notice

Because all food and drink is prepared in shared kitchen environments and using shared equipment (like espresso steam wands and tongs), Costa cannot guarantee that any product is entirely free from allergens due to the risk of cross-contact.

If you have a severe allergy, extra caution is required. Always declare your allergy to the barista before ordering, and check Costa's current official allergen guide online at costa.co.uk as recipes and ingredients change regularly.
