Starbucks UK publishes total sugar for every drink, but total sugar includes the lactose in milk, which health guidance does not limit. Boone separates free sugars, the added and syrup sugars SACN caps at 30g a day for an adult, and ranks all 405 items on that basis. A Grande Caffè Latte shows 14.2g of total sugar but 0g of free sugar, because almost all of it is lactose.
The Pumpkin Spice Coffee Frappuccino (Venti) leads the menu at 52.6g of free sugar, 175% of an adult's daily limit and 277% of the 19g limit for a four to six year old. 50 items on the UK menu exceed the adult limit on their own, and 123 exceed the limit for a young child. Switching to a plant milk usually raises the free sugar rather than lowering it, because oat, almond, soya and coconut sugars are released by processing and do count.

Figures are per portion as served, from Starbucks UK published nutrition information, checked August 2026. Items are excluded where Starbucks does not publish a complete nutrition breakdown.
Boone derives free sugars rather than using the total sugar Starbucks publishes. Lactose in milk is deducted at 1.3g per gram of milk protein, a ratio taken from Starbucks' own unsweetened milk drinks, because NHS daily limits do not count the sugars naturally present in milk. Sugars in oat, almond, soya and coconut drinks are counted as free sugars, because they are released by processing rather than naturally present.
Daily free sugar limits are 30g for adults and teenagers, 24g for ages 7 to 10 and 19g for ages 4 to 6.
Every drink is listed with semi-skimmed milk, the default Starbucks serves unless you ask otherwise. Oat, almond, soya and coconut versions of each drink have their own pages and can be compared in the calculator on any item page. Each size is listed separately, because size changes the figures more than flavour does.
