Tea
Costa’s tea range covers the classics — English Breakfast, Earl Grey, Green, Mint — alongside a small line-up of fruit and vitamin-enriched infusions, plus a matcha latte for something in between tea and coffee. Most of these are naturally low or free of calories. We only add figures here once independently confirmed.

Product Descriptions
Pure Chamomile Infusion
Dried chamomile blossoms alone, no blend and no added flavouring. Floral and mild, and the only tea on the menu with zero caffeine and zero other ingredients.
Matcha Latte
Whisked matcha powder and steamed milk. Grassier and more vegetal than a standard tea, with a caffeine level closer to coffee than to black tea.
Decaf Tea
Standard black tea with the caffeine removed. Same everyday flavour as the English Breakfast Tea, aimed at anyone avoiding caffeine later in the day.
English Breakfast Tea
A classic blend of black teas, strong and malty. The most straightforward, high-caffeine option on the tea list.
Earl Grey Tea
Black tea scented with bergamot oil, giving it a distinct citrus note that sets it apart from the plainer black teas on the menu.
Green Tea
Steam-dried green tea leaves from Eastern China. Lighter and less tannic than the black teas, with lower caffeine too.
Mint Tea
A blend of peppermint and spearmint leaves, with no tea base at all. Naturally caffeine-free and one of the more intensely flavoured options.
Citrus Zing with Vitamin C
Green tea with lemon and ginger, fortified with Vitamin C and served with a fresh lemon slice. Sharper and spicier than the plain Green Tea.
Spiced Apple with Vitamin B6
Green tea with apple and cinnamon, fortified with Vitamin B6 and served with a cinnamon stick. Warmer and sweeter than the Citrus Zing.
Berry Infusion
A single-note summer berry infusion, light and gently sweet rather than tart, with no tea base and no caffeine.
Pricing & Sourcing Notes
Cup Sizes & Pricing
Costa offers four sizes: Small (8 fl oz), Medium (12 fl oz), Large (16 fl oz) and Extra Large (20 fl oz). Prices shown are for Medium. Small and Large typically cost differently, but we haven’t independently confirmed the exact difference yet — check in-store or via the Costa app for current size pricing. Milk alternatives (oat, soya or coconut — Costa’s guide doesn’t list an almond option) may also carry a small surcharge, which we haven’t confirmed. Not every drink can be made dairy-free with a swap, though — see our Milk & Dairy Alternatives guide for the full list.
Pricing Note
Prices shown are independent research, not official Costa pricing, and may vary by store. Calorie figures are taken from Costa’s own published nutrition guide where confirmed. Where you see ‘Price not verified’ instead of a number, it means we don’t yet have a reliable figure from either Costa’s own data or two independent sources agreeing — rather than publish a guess, we leave it blank until we can confirm it.
