Starbucks Espresso contains 10 kcal per doppio (double shot) — less than 1% of the adult 2,000 kcal daily reference intake. A solo (single shot) contains approximately 5 kcal. The negligible calorie count comes from the very small amount of soluble coffee solids dissolved in the espresso — coffee beans themselves are calorie-dense but the extraction process carries only a tiny fraction of those calories into the cup. It is one of the lowest calorie items at Starbucks alongside Chamomile Tea, Mint Majesty Tea, Americano and Cold Brew.

Per doppio (double shot): 10 kcal, 0.2g fat (0.1g saturated), 1.3g carbohydrate, 0g sugar, 0.6g protein, 0g salt, 150mg caffeine. Per solo (single shot): approximately 5 kcal, 0.1g fat, 0.7g carbohydrate, 0g sugar, 0.3g protein, 0g salt, 75mg caffeine. Every figure except caffeine is effectively zero. There is no added sugar and no dairy in any standard espresso preparation.

Starbucks Espresso contains approximately 75mg of caffeine per solo (single shot) and 150mg per doppio (double shot). The doppio at 150mg uses 38% of the NHS daily maximum of 400mg for adults. A triple shot contains approximately 225mg. The doppio at 150mg is within the NHS recommended daily maximum for pregnancy of 200mg when no other caffeine is consumed — a solo at 75mg is the most conservative pregnancy-appropriate option. The NHS recommends a maximum of 400mg per day for most adults and 200mg per day during pregnancy.

Starbucks Espresso contains 0g of sugar per solo or doppio — no free sugars, no natural sugars, no lactose. It is one of the very few items at Starbucks with zero sugar alongside Chamomile Tea, Mint Majesty Tea, Americano, Cold Brew and Freshly Brewed Coffee. The characteristic bittersweet flavour of espresso comes from the roasted coffee compounds — not from any actual sugar content. Adding a sugar sachet, syrup or honey at the counter introduces free sugars.

No. NOVA 1 — unprocessed. Espresso is roasted and ground coffee beans extracted under high pressure with hot water — a purely physical process with no additives, no flavourings and no preservatives. Roasting is considered a minimal transformation that preserves the NOVA 1 classification. It sits alongside Chamomile Tea, Mint Majesty Tea, Cold Brew and the Americano as one of the very few NOVA 1 items on the Starbucks menu. It is as unprocessed as coffee can be in a commercial setting.

Starbucks Espresso contains none of the 14 major allergens. It does not contain milk, wheat/gluten, egg, soya, peanuts, tree nuts, fish, shellfish, celery, mustard, sesame, lupin, molluscs or sulphites. Coffee is not one of the 14 major allergens in the UK. It is one of the most allergen-free items on the entire Starbucks menu. Starbucks prepares all drinks in stores where all 14 major allergens are present — cross-contamination cannot be guaranteed. Always tell your barista if you have a severe allergy before ordering.

Yes. Starbucks Espresso is suitable for both vegetarians and vegans. It contains no animal-derived ingredients — roasted coffee and water only. It is gluten-free and allergen-free. It is one of the most inclusive items on the Starbucks menu, suitable for any dietary requirement in its standard preparation.

No. Starbucks Espresso contains approximately 75mg of caffeine per solo and 150mg per doppio — well above safe levels for children based on FSA guidance of 3mg per kg of body weight per day. The NHS advises children should avoid caffeine where possible. Chamomile Tea and Mint Majesty Tea are the caffeine-free alternatives at Starbucks.

A solo (single shot) at approximately 75mg of caffeine is well within the NHS recommended pregnancy maximum of 200mg per day when no other caffeine is consumed. A doppio at 150mg remains within the pregnancy limit but uses 75% of it in a single small drink — accounting for caffeine from other sources throughout the day is essential. A triple shot at approximately 225mg exceeds the pregnancy limit. For most pregnant people who want espresso, a solo is the most appropriate choice. If in doubt, consult a midwife or GP.

A solo is a single shot of espresso — approximately 30ml of liquid, 75mg of caffeine and 5 kcal. A doppio is a double shot — approximately 60ml, 150mg of caffeine and 10 kcal. At Starbucks the doppio is the default espresso serving. A doppio is made by pulling two shots simultaneously through a double basket portafilter — producing a richer, more balanced flavour than simply pulling two separate singles. Most Starbucks drinks that include espresso use the equivalent of a doppio per Tall or Tall-equivalent size.

Both Espresso and the Americano are NOVA 1, vegan, allergen-free and contain 0g of sugar. The Americano is espresso diluted with hot water to produce a larger, lighter-bodied drink — a Tall Americano contains approximately 134mg of caffeine from one or two shots in a larger volume. A doppio Espresso contains 150mg of caffeine in approximately 60ml. The espresso is more concentrated and intense; the Americano is gentler and more similar in volume and body to filter coffee. Nutritionally they are near-identical — the choice is entirely one of flavour and volume preference.

Starbucks Espresso is the purest, most concentrated coffee drink on the menu — 10 kcal, 0g sugar, no allergens, NOVA 1, vegan. It is also the base ingredient for the majority of other drinks at Starbucks — every Caffe Latte, Cappuccino, Caramel Macchiato, Flat White and Americano starts with espresso. As a standalone drink it is the most nutritionally neutral caffeinated option at Starbucks — nothing added, nothing removed, just coffee. For adults who want maximum flavour intensity with zero sugar, zero allergens and minimal calories, the Espresso is the definitive choice.
