Starbucks has rotated through milk alternatives for years, and I’ve paid attention to the lineup mostly when I’m deciding how to order a drink.
For me, it matters because the right milk lets a familiar drink stay familiar even when I want something lighter, dairy-free, or just a little less sharp.
The question I kept coming back to was simple: what soy milk does Starbucks use?
The answer only really clicked for me once I looked at the ingredients, calories, and how it actually tastes in coffee.
Key takeaways
What brand of soy milk does Starbucks use?
Starbucks began offering plant-based milk products to US customers in 1997 and has used a few types and brands over the years.
The soy milk Starbucks uses is a special recipe made by Danone specifically for the chain.
Danon was chosen by Starbucks due to their consideration of environmental factors, among other qualities.
The soy milk Starbucks offers is available exclusively in-store, and I love the not-too-sweet taste!
Is the soy milk that Starbucks uses healthy?
Is it natural/organic?
Starbucks soy milk is natural and organic.
The ingredients list includes evaporated cane juice, calcium carbonate, sea salt, carrageenan, sodium citrate, baking soda, and added vitamins.
Is it sweetened?
Starbucks plant-based soy milk is lightly sweetened with cane juice and natural vanilla flavor.
That mix helps explain why Starbucks' soy milk tastes a little smoother and sweeter than some other plant milks once it’s steamed.
Is it gluten free?
Starbucks’ soy milk plant-based milk alternative is listed as gluten-free.
It’s also dairy-free and GMO-free.
How many calories are in Starbucks soy milk?
An 8-ounce cup of Starbucks soy milk has around 130 calories.
The other milk alternatives are lower in calories. Oat milk is the second highest at around 140 calories, followed by Starbucks coconut milk at 80 and almond milk at 60.
Soy milk also has the highest sugar content at 13 grams per 8 ounces, with oat and coconut at 7 grams and almond milk at 5 grams.
It also has 16 grams of carbs, compared with 7 grams for almond and coconut milk.
Benefits of soy milk in coffee and tea drinks
I like Starbucks soy milk in coffee drinks when I want a dairy-free option that still feels fairly rich.
I notice the creaminess before anything else. Compared with almond or coconut milk, Starbucks' soy milk feels fuller, and the light vanilla note comes through clearly in a latte.
That’s why I usually think of it as a vegan or lactose-free order rather than just another milk swap.
I’d be cautious about the bigger health claims around soy. The osteoporosis and heart disease points are better treated as broad nutrition claims than as guarantees from one drink.
Other kinds of plant-based milk that Starbucks use
Starbucks also offers coconut milk, oat milk, and Almond Breeze almond milk alongside soy milk.
Those milk options usually cost a little more than dairy milk or cream.
FAQs
Where can you buy Starbucks soy milk?
The Starbucks soy milk I see in-store is the Danone version, and Danone also sells a similar soy Silk range in US supermarkets.
Is Starbucks soy milk keto-friendly?
Based on the sugar content, I would not treat Starbucks soy milk as keto-friendly.
Does Starbucks charge more for soy milk?
Starbucks charges an extra 70 cents per drink for soy milk.
Final words
I only really appreciated Starbucks' soy milk after making a soy latte at home with a different brand.
Starbucks' version tastes creamier to me, with a slightly sweet vanilla finish that I notice in coffee straight away.
That’s also why I still reach for it when I want a dairy-free milk with a softer, sweeter finish.
