Starbucks oat milk Vs. Regular milk – How They Compare.

Starbucks regular milk


Oat milk is plant-based milk made from milling a combination of oat and water, which are the main ingredients. Synthetic vitamins and minerals are added to boost the nutritional value of the milk. For instance, Riboflavin, vitamin A, vitamin D2, and vitamin B12 are added to increase the vitamin composition. Additionally, dipotassium phosphate, dicalcium phosphate, tricalcium phosphate, calcium carbonate, and sea salt are added to increase milk’s mineral composition, especially calcium and phosphorus.

The regular Starbucks milk is made from dairy milk. Milk is the sole ingredient responsible for flavor and nutritional components.

Oat milk wins in this category because it has many ingredients that ensure the consistency of minerals, proteins, and vitamins. The nutritional composition of cow milk may vary slightly depending on what a cow is fed.

Taste profile

The first thing you will note about the taste of oat milk is that it is slightly sweeter than regular milk. A keen person will also notice a delicious nutty note and a smooth, creamy texture that enhances the taste. So, the milk is delicious, sweet, and creamy.

The regular milk has a sweet taste that is not as strong as the oat milk. It is delicious and creamy. It has a smooth texture and is pretty much enjoyable.

This category has no winner because oat milk and regular milk have similar tastes. Although the oat milk is slightly sweeter, its taste is not significantly different.

Caffeine content/ Nutritional value

The oat milk has zero caffeine and 140 calories in a 240 ml cup. Although caffeine is not expected in milk, the calorie is enough to keep you energized but not significantly high to cause adverse health impacts. Another crucial aspect of the nutritional value of oat milk is minerals and vitamins. It has more calcium and phosphorus than regular milk. It also has a wider variety of vitamins than regular milk.

On the other hand, Starbucks uses 2% regular milk that has 140 calorie counts. The calories are the same as in oat milk. It also has 25mg of cholesterol, which is unhealthy, especially for individuals who consume a lot of milk daily. Cholesterol causes heart-related problems. It has more protein than oat milk, making it better for growing children. Calcium, vitamins, and other minerals are slightly lower than in oat milk.

Oat milk wins in this category because it is healthier and has more vitamins and minerals. It is healthier due to its zero-cholesterol content. Although regular milk has more proteins, it loses out on being the most nutritious because it has fewer vitamins and low mineral content, especially calcium. Finally, oat milk is vegan and serves more people than regular milk.


The oat milkis readily available in all Starbucks storesacross the US. It was first tested in the Midwest Starbucks store and was later distributed in all Starbucks stores in 2021. Additionally, Starbucks uses the Oatly Oat Milk brand that is available in stores and groceries across the US. You can therefore purchase it for use at home.

Regular milk is also available in all Starbucks across the country. Starbucks uses several milk brands, one of which is Lucerne 2% milk, which you can access at any store or grocery across the US. It is therefore accessible and available at Starbucks and for use at home if you wish.

There is no winner in this category because the two types of milk are readily available and easily accessible at Starbucks and in stores and groceries across the country.


Oat milk has a longer and more complicated manufacturing process. Mixing water and the right oat and adding synthetic vitamins and minerals is a long and tedious process. The milk must be made so that it does not separate when added to the drinks and must have an acidity regulator.

On the other side, regular milk has straightforward processing, which involves pasteurization, skimming, and re-addition of fat to reach 2%.

Regular milk wins in this category because of its straightforward processing. However, the assessment for regular milk processing does not consider the rearing of dairy animals and the milking processes. Oat milk processing also does not account for the growing oats used to make oat milk.
