Almond milk has become a staple for many seeking a dairy-free alternative. Yet, the texture can vary dramatically from brand to brand, and between store-bought and homemade versions. The difference is largely due to the concentration of almonds and the inclusion of thickening agents, which can be either natural kitchen ingredients or commercial food additives. Understanding these factors is key to knowing what makes almond milk thick.
The Role of Almond Concentration and Ratio
At its core, the thickness of almond milk is directly proportional to its almond content. Homemade almond milk allows for full control over this ratio, with a higher proportion of almonds to water yielding a naturally richer and creamier result. In contrast, commercial manufacturers often use a very low almond concentration to reduce costs, resulting in a thin and watery product. To compensate for this low nut content, companies add various thickeners to create a more palatable texture that mimics dairy milk.
For homemade preparations, soaking raw almonds is a critical step. Soaking softens the nuts, allowing them to blend more smoothly and release more of their natural oils and starches into the liquid, contributing to a thicker, creamier emulsion. Skipping this step or not blending for a sufficient duration can lead to a thin, gritty consistency.
Common Thickeners in Store-Bought Almond Milk
Food companies use a variety of additives to stabilize and thicken their products, ensuring a consistent texture and preventing separation during storage. These ingredients are often listed on the carton and are the primary reason why some brands are notably thicker than others.
Gums and Stabilizers
- Xanthan Gum: Derived from fermented sugars, xanthan gum is a popular, natural thickening agent that creates a smooth, uniform texture. It is effective even in very small quantities and is widely used in many plant-based milks.
- Gellan Gum: This bacterial polysaccharide is used as a gelling agent and stabilizer. It is particularly effective at suspending particles, such as added calcium, throughout the milk, preventing them from settling at the bottom. High-acyl variants of gellan gum can also add viscosity and elasticity.
- Carrageenan: An extract from red seaweed, carrageenan functions as both an emulsifier and thickener. However, due to some controversial studies linking it to gastrointestinal issues, many brands have moved away from using it.
- Guar Gum and Locust Bean Gum: These are also used to improve texture, but like some other gums, have been associated with potential gastrointestinal discomfort for sensitive individuals.
Emulsifiers
Emulsifiers help prevent the natural separation of fats and liquids, creating a smooth and creamy mouthfeel. The primary emulsifier used in many commercial almond milks is Lecithin, which is often derived from sunflowers or soybeans.
Homemade Techniques for a Thicker Result
For those making almond milk at home and seeking a thicker consistency without commercial additives, several simple methods can be employed:
- Adjusting the Ratio: As mentioned, a higher nut-to-water ratio is the simplest way to increase thickness.
- Soaking: A longer soak time (overnight is ideal) allows the almonds to soften completely for a creamier blend.
- Scalding: Heating almond milk to just below boiling point (scalding) can cause the almond particles to permanently thicken the liquid, resulting in a significantly more viscous texture.
- Adding Other Ingredients: Incorporating ingredients rich in fat or fiber can naturally thicken homemade milk. Options include: Adding a handful of cashews: The higher fat content and softness of cashews can greatly increase creaminess. Adding ground chia or flax seeds: These seeds absorb liquid and expand, acting as a natural binder. Using coconut cream: Combining almond milk with coconut cream can create a very rich, thick mixture perfect for coffee or sauces.
- Less Straining: Leaving a small amount of the finest pulp in the milk, rather than straining it completely with a nut milk bag, can add body and texture.
Comparison: Homemade vs. Store-Bought Almond Milk
| Feature | Homemade Almond Milk | Store-Bought Almond Milk | 
|---|---|---|
| Almond Content | Can be controlled, often 10% or more for creaminess. | Very low, often 2-3% almonds. | 
| Thickeners | Optional natural additions like cashews, chia seeds, or heat. | Commercial gums (xanthan, gellan) and emulsifiers (lecithin) are common. | 
| Consistency | Highly customizable, from thin to extra thick and creamy. | Engineered to a consistent texture, but often watery without additives. | 
| Additives | Additive-free, allowing for a cleaner ingredient list. | May contain sweeteners, flavorings, and preservatives. | 
| Separation | Natural separation can occur and requires a good shake. | Additives prevent separation, ensuring product stability. | 
The Effect of Heat
Heat can dramatically affect the texture of almond milk, both in homemade and commercial versions. Heating homemade almond milk to a high temperature, just before boiling, can permanently thicken it. This process is known as scalding. However, store-bought milk is often treated with stabilizers that react differently to heat, and some batches may curdle or split when heated. The difference lies in the protein and fat structures, with commercial versions having been homogenized and stabilized with additives to withstand some heat, but not always enough for every application.
Conclusion
In summary, what makes almond milk thick is not a single factor but a combination of ingredient ratios and thickening agents. For commercially produced almond milk, the answer lies in sophisticated food additives like xanthan and gellan gums, which compensate for a low almond content to create a desirable texture. For homemade almond milk, the thickness is determined by the almond-to-water ratio and techniques such as soaking and heating. While additives provide convenience and stability for manufacturers, home cooks can achieve a rich, creamy consistency naturally by adjusting their preparation methods. Whether you prefer the consistency of store-bought or the control of homemade, understanding these principles empowers you to choose or create the perfect almond milk for your needs.

The Almond Milk Thickness Equation
To achieve a creamy texture, both homemade and store-bought almond milk rely on specific strategies. Store-bought versions use additives like gums and emulsifiers to create a consistent mouthfeel, while homemade options achieve this by adjusting the almond-to-water ratio or incorporating natural thickeners. A higher concentration of almonds results in a naturally thicker, richer, and more nutritious milk. Some commercial additives, particularly carrageenan, have raised health concerns, prompting some brands to remove them. Heating homemade almond milk to a high temperature can also cause it to thicken permanently. For homemade milk, using soaked almonds and a powerful blender helps produce the creamiest result. Natural emulsifiers like sunflower lecithin or added ingredients such as cashews can enhance the richness and prevent separation.
