Every Starbucks protein drink ranked by protein

The Iced Protein Matcha, the Iced Caramel Protein Matcha and the Iced Sugar-Free Vanilla and Caramel Protein Matchas have the most protein of any Starbucks protein drink: 31 g in a grande. The two sugar-free matchas get there with the fewest calories, 210.

Protein per 100 cal is the grams of protein you get for every 100 calories: protein divided by calories, times 100. The higher it is, the more protein you get for the calories you drink.

Sixteen of the 19 drinks have 27 to 31 g of protein in a grande. The three protein cream drinks at the bottom are a different kind of drink, and they get their own section below.

Best low-calorie Starbucks protein drinks: the sugar-free versions

The lowest-calorie Starbucks protein drinks are the Iced Sugar-Free Vanilla Protein Latte and the Iced Sugar-Free Caramel Protein Latte: 200 calories, 29 g of protein and 9 g of sugars in a grande. Choosing the sugar-free version of a protein drink saves 60 to 90 calories and 14 to 22 g of sugars, and the protein stays the same.

Here is what you save by switching each regular drink to its sugar-free twin, at grande size.

Drink (grande)	Regular calories	Sugar-free calories	Calories saved	Sugars saved (g)
Iced Vanilla Protein Latte	270	200	70	20
Iced Caramel Protein Latte	280	200	80	22
Iced Caramel Protein Matcha	270	210	60	14
Vanilla Protein Latte (hot)	310	230	80	19
Caramel Protein Latte (hot)	320	230	90	22
Caramel Protein Matcha (hot)	310	240	70	16

Sugar-free doesn’t mean zero sugar here. A grande sugar-free protein latte or matcha still lists 9 to 16 g of sugars. The vanilla matchas aren’t in the table because they have no regular version with the same name to compare against.

Starbucks protein lattes vs protein matchas, hot vs iced

In a grande, Starbucks’ protein matchas have a little more protein than its protein lattes and much less caffeine. A grande Iced Protein Matcha has 31 g of protein and 65 mg of caffeine, while a grande Iced Vanilla Protein Latte has 29 g and 150 mg.

Calories are close, within 10 of each other for the matching latte and matcha. So the choice mostly comes down to caffeine: every grande protein latte has 150 mg, and the grande protein matchas have 65 to 75 mg (55 mg in the Iced Banana Protein Cream Matcha).

At grande size, iced beats hot. Each iced grande has 2 to 3 g more protein than its hot version and 30 to 40 fewer calories. The Iced Vanilla Protein Latte has 29 g of protein for 270 calories, against 27 g for 310 in the hot Vanilla Protein Latte. The iced drinks also have less fat, 4 to 4.5 g against 6 to 7 g. In a tall it flips for protein: the hot versions have 1 to 4 g more.

Tall, Grande or Venti: how size changes protein in Starbucks drinks

Sizing up adds the most protein to Starbucks’ iced protein lattes and matchas. A venti Iced Sugar-Free Vanilla Protein Latte has 40 g of protein for 280 calories, 11 g more than the grande, and a venti iced protein matcha has 50 g.

Hot ventis add much less, just 2 to 4 g of protein over a grande. A hot venti holds 20 fl oz, while an iced venti holds 24 fl oz.

Drink and size	Calories	Protein (g)	Protein per 100 cal	Sugars (g)	Caffeine (mg)
Iced Sugar-Free Vanilla Protein Latte, Tall (12 fl oz)	150	22	14.7	7	75
Iced Sugar-Free Vanilla Protein Latte, Grande (16 fl oz)	200	29	14.5	9	150
Iced Sugar-Free Vanilla Protein Latte, Venti (24 fl oz)	280	40	14.3	13	225
Iced Sugar-Free Vanilla Protein Matcha, Tall (12 fl oz)	130	18	13.8	6	35
Iced Sugar-Free Vanilla Protein Matcha, Grande (16 fl oz)	210	31	14.8	10	65
Iced Sugar-Free Vanilla Protein Matcha, Venti (24 fl oz)	340	50	14.7	17	95
Vanilla Protein Latte (hot), Short (8 fl oz)	150	14	9.3	16	75
Vanilla Protein Latte (hot), Tall (12 fl oz)	240	23	9.6	25	75
Vanilla Protein Latte (hot), Grande (16 fl oz)	310	27	8.7	34	150
Vanilla Protein Latte (hot), Venti (20 fl oz)	360	29	8.1	43	150

Checked against Starbucks’ official nutrition information on 22 October 2026.

On the two iced sugar-free drinks, protein per 100 calories stays between 13.8 and 14.8 from tall to venti, so a bigger cup is simply more of the same. A venti Iced Sugar-Free Vanilla Protein Matcha has 50 g of protein for 340 calories, tied with the caramel version for the most protein per calorie at that size.

The hot latte works the other way. Going from a grande to a venti Vanilla Protein Latte adds 50 calories and 9 g of sugars for 2 g of protein, and the caffeine stays at 150 mg.

Starbucks protein cream drinks: what you get for the calories

Starbucks’ three protein cream drinks give the least protein for their calories on its protein menu. A grande Iced Vanilla Protein Cream Shaken Espresso has 19 g of protein for 410 calories, while a grande Iced Sugar-Free Vanilla Protein Latte has 29 g for 200.

Drink (grande)	Calories	Protein (g)	Protein per 100 cal	Fat (g)	Sugars (g)
Iced Banana Protein Cream Matcha	400	23	5.8	17	38
Iced Vanilla Protein Cream Shaken Espresso	410	19	4.6	20	28
Vanilla Protein Cream Cold Brew	300	17	5.7	16	23
Iced Sugar-Free Vanilla Protein Latte (for comparison)	200	29	14.5	4	9

Checked against Starbucks’ official nutrition information on 22 October 2026.

The cream drinks have 16 to 20 g of fat in a grande, against 4 to 7 g in the protein lattes and matchas. The Iced Banana Protein Cream Matcha has 38 g of sugars, the most of any grande on the protein menu. The Vanilla Protein Cream Cold Brew is the lightest of the three at 300 calories, with 205 mg of caffeine.

Adding protein cold foam to another drink, or switching milk, changes all of these numbers, so check the drink you actually order.
