Serving	Total sugar	Free (added) sugar	Naturally occurring	Free sugar in teaspoons
Per serving	34g	16.5g	17.5g	4.1 tsp

Made with semi-skimmed milk, about 17.5g of the sugar in this drink is lactose, which occurs naturally in milk and does not count towards NHS free sugar limits. That leaves 16.5g of free sugar.

Boone derives the lactose figure from the milk protein in each build, at 1.25g of lactose per gram of milk protein, a ratio taken from Costa's own unsweetened milk drinks where all of the sugar is lactose.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6.
