The last few years have seen an eco and health-conscious revolution take over the food and beverage industry, as the demand for non-dairy milk and other plant-based alternatives is booming [1]. People have become widely informed about the benefits of these cruelty-free products for their diet, especially so when it comes to milk. It has certainly opened up a wide array of options for those suffering from lactose intolerance too.

Now there is no lack of options when it comes to these products: supermarkets and everywhere else are flooded with different types of plant-based milks. So now the new question that has arisen is, which plant-based milk is better? And the dilemma is often oat milk vs soy milk. We’re here to help you make your choice by laying down all the facts!

Soy Milk originates from grinding and filtering soya beans which gives a smooth liquid. It is also known as soya milk and is an emulsion of protein, water, and oil.

What is Oat Milk?

Oat Milk vs Soy Milk: Taste and Texture Comparison

This is a huge factor that helps in deciding what to switch to when it comes to milk that suits your flavor palette. Soy milk taste, with its mildly nutty flavor and creamy feel, closely resembles traditional dairy milk, making it a popular choice for those seeking a similar texture and taste.

Oat Milk

Oat milk fans are those who like a neutral, naturally sweet flavor. It can also have a slight oatmeal taste to it and is available in flavors like vanilla, chocolate, sweetened, unsweetened, etc.

The sweetness isn’t dominating and is quite subtle, and this is infused with a creamy liquid that can feel quite close to dairy milk and is neither too thick nor too watery. So if you still crave the consistency of dairy milk, you might like to go for this choice. Oat milk’s creamy texture and mild sweetness make it a favorable alternative to traditional dairy milk.
