Starbucks Iced Caramel Protein Latte contains 210 kcal in a Tall (12oz), 270 kcal in a Grande (16oz) and 330 kcal in a Venti (24oz) — 11%, 14% and 17% of the adult 2,000 kcal daily reference intake respectively. It is marginally higher in calories than the Iced Vanilla Protein Matcha Latte at equivalent sizes due to the caramel flavouring adding a small amount of additional sugar and calories versus the matcha component. The espresso shots, caramel flavouring and vanilla protein milk base combine to produce one of the most calorie-efficient high-protein drinks available at Starbucks.

Tall (12oz): 210 kcal, 4g fat (1.5g saturated), 20g carbohydrate (14g sugar), 20g protein, 0.38g salt. Grande (16oz): 270 kcal, 5g fat (2g saturated), 26g carbohydrate (18g sugar), 27g protein, 0.49g salt. Venti (24oz): 340 kcal, 7g fat (2.5g saturated), 33g carbohydrate (23g sugar), 34g protein, 0.60g salt. The protein-to-calorie ratio is exceptional — 20g protein for 210 kcal in a Tall — and the saturated fat is low across all sizes reflecting the protein milk base.

Starbucks Iced Caramel Protein Latte contains 14g of sugar in a Tall, 18g in a Grande and 23g in a Venti — 47%, 60% and 77% of the adult daily free sugar limit of 30g respectively. The Venti at 23g approaches the adult daily limit from a single drink. The sugar comes from the caramel flavouring syrup, the vanilla protein milk base and the naturally occurring lactose in the milk proteins. At Tall and Grande sizes the Iced Caramel Protein Latte is moderate in sugar relative to other sweetened Starbucks iced drinks — a Grande Iced Caramel Macchiato contains 23g and a Grande Iced Chai Tea Latte contains 28g. The NHS free sugar limit is 30g per day for adults, 24g for children aged 7 to 10, and 19g for children aged 4 to 6.

Starbucks Iced Caramel Protein Latte contains 20g of protein in a Tall, 27g in a Grande and 34g in a Venti — 40%, 54% and 68% of the adult daily reference intake of 50g respectively. Equal to the Iced Vanilla Protein Matcha Latte at equivalent sizes — both drinks use the same vanilla protein milk base. This is the highest protein of any espresso-based drink at Starbucks by a very significant margin. A standard Grande Iced Caffe Latte with semi-skimmed milk contains approximately 10g protein — the Iced Caramel Protein Latte Grande delivers 27g, almost three times as much.

Starbucks Iced Caramel Protein Latte contains approximately 75mg of caffeine in a Tall (1 shot of espresso), 150mg in a Grande (2 shots) and 225mg in a Venti (3 shots). The caffeine comes entirely from the espresso shots — there is no additional caffeine from the protein milk or caramel flavouring. The Venti at 225mg approaches the NHS recommended daily maximum of 400mg for adults. For those monitoring caffeine intake, a Tall or Grande is the appropriate size. The NHS advises a maximum of 200mg per day during pregnancy — a Grande therefore reaches this limit in a single drink.

Starbucks Iced Caramel Protein Latte contains 1.5g of saturated fat in a Tall, 2g in a Grande and 2.5g in a Venti — 8%, 10% and 13% of the adult daily guideline of 20g respectively. The saturated fat is low across all sizes — the protein milk base is formulated to maximise protein while keeping fat content lower than standard dairy milk. The espresso shots and caramel flavouring contribute negligible saturated fat.

Yes. NOVA 4, ultra-processed. The vanilla protein milk base is an industrially formulated dairy product containing protein isolates, stabilisers and flavourings beyond what standard milk contains. The caramel flavouring syrup contains glucose-fructose syrup, flavourings and preservatives. The espresso is NOVA 1 — minimally processed — but the formulated protein milk base determines the overall NOVA 4 classification. Despite the fitness positioning, the industrial formulation of the protein milk component places the drink in the most processed category.

Starbucks Iced Caramel Protein Latte contains milk and soya as declared allergens. The milk comes from the vanilla protein milk base. The soya comes from soya lecithin or soya protein used as a component in the formulated protein milk blend. It does not contain wheat/gluten, egg, peanuts, tree nuts, fish, shellfish, celery, mustard, sesame, lupin or molluscs. Gluten-free by ingredients though Starbucks cannot guarantee cross-contamination in store. Always tell your barista if you have a severe allergy before ordering.

Starbucks Iced Caramel Protein Latte is suitable for vegetarians. It is not suitable for vegans as the protein milk base uses dairy-derived milk proteins. Switching to oat or almond milk would maintain the caramel latte format but would reduce the protein from 20g per Tall to approximately 3-4g — losing the core nutritional differentiator of the drink. There is currently no vegan protein milk alternative at Starbucks that preserves the high protein content.

No. Starbucks Iced Caramel Protein Latte is not suitable for children. A Tall contains approximately 75mg of caffeine from a single espresso shot — the NHS advises children avoid caffeine where possible. A Grande at 150mg and Venti at 225mg are well above any safe caffeine level for children. The caramel flavouring adds sugar at 14g per Tall — 74% of the daily free sugar limit for a child aged 4 to 6. The very high protein content — 20g per Tall — is also well above appropriate protein intake from a single drink for younger children.

A Tall delivers 20g of protein from one shot of espresso at 75mg caffeine — a moderate caffeine dose well within daily limits for most adults. A Grande at 27g protein and 150mg caffeine remains within the NHS recommended daily maximum of 400mg. A Venti at 34g protein and 225mg caffeine uses 56% of the daily maximum in a single drink. For those prioritising protein while managing caffeine intake, a Tall or Grande is the most appropriate size. For those with caffeine sensitivity, the Iced Vanilla Protein Matcha Latte delivers equivalent protein with lower caffeine and the L-theanine moderating effect of matcha.

A Grande Iced Caramel Macchiato contains approximately 250 kcal, 23g sugar and 10g protein. A Grande Iced Caramel Protein Latte contains 270 kcal, 18g sugar and 27g protein. The Protein Latte is 20 kcal higher but delivers 17g more protein and 5g less sugar. For those who enjoy a caramel coffee flavour and are monitoring protein intake, the Iced Caramel Protein Latte is substantially more nutritionally efficient. The trade-off is the slightly sweeter base from the flavoured protein milk versus the espresso-forward profile of the Caramel Macchiato.

Both use the same vanilla protein milk base and deliver identical protein across equivalent sizes — 20g Tall, 27g Grande, 34g Venti. The Caramel Protein Latte contains 10 more calories per size from the espresso and caramel, and 2g more sugar per size from the caramel syrup. The key difference is caffeine delivery: the Caramel Latte uses espresso (75mg per Tall shot) for a sharper caffeine effect; the Matcha Latte uses matcha (approximately 55mg per Tall) for a gentler, L-theanine-moderated effect. For equivalent protein with slightly lower calories and sugar, the Matcha Latte is marginally better. For a coffee flavour and stronger caffeine, the Caramel Latte is the choice.

Starbucks Iced Caramel Protein Latte is jointly the highest protein drink on the Starbucks menu alongside the Iced Vanilla Protein Matcha Latte at 20g per Tall, 27g per Grande and 34g per Venti. It delivers this protein at low saturated fat (1.5-2.5g across sizes) and moderate sugar (14-23g). The espresso base gives it a more assertive caffeine profile than the matcha version. It contains milk and soya allergens, is not suitable for vegans and is NOVA 4. For adults seeking a high-protein espresso-based iced coffee at Starbucks with a caramel flavour, the Iced Caramel Protein Latte is the standout choice — delivering nearly three times the protein of a standard Iced Caffe Latte at a comparable calorie level.
