Oatly vs Califia: Which Is Better?

Oatly and Califia Farms are two of the most recognisable names in the plant milk market. Oatly is the Swedish brand that essentially created the premium oat milk category, while Califia Farms is a California-based brand known for its almond and oat milk ranges. If you are choosing between them at the supermarket, here is what the comparison looks like in practice.

The Products

This comparison focuses on each brand's standard oat milk products — Oatly Original versus Califia Farms Oat Barista Blend — since these are the most widely purchased and comparable products from each brand. Both are oat-based, both are designed for everyday use including coffee, and both are widely available in supermarkets and coffee shops.

Calories and Macronutrients

Per cup (240ml), Oatly Original contains approximately 120 calories, 3g protein, 5g fat, and 16g carbohydrates. Califia Farms Oat Barista Blend is broadly comparable at around 130–140 calories per cup with similar macronutrient distribution. Both are unsweetened in their standard formulations but contain natural oat sugars from the enzymatic processing of oats.

The differences between the two brands on macronutrients are small — within the normal variation you would expect between different batches and formulations. Neither has a significant nutritional advantage over the other in their standard oat milk products.

Ingredients

Oatly's ingredient list is notably short: oat base (water, oats), rapeseed oil, and small amounts of dipotassium phosphate and calcium carbonate. Califia Farms' ingredients list is slightly longer, typically including oat base, sunflower oil, and a broader range of stabilisers and fortification agents. Both are free from dairy, soy, and nuts in their oat milk products.

Taste and Performance in Coffee

Both brands perform well in coffee, which is where most premium plant milks are tested hardest. Oatly has a slightly sweeter, more neutral flavour that many baristas and coffee shops prefer. Califia's Barista Blend has a slightly richer, creamier texture that some people prefer for lattes and flat whites. Both froth well and are unlikely to split when added to espresso-based drinks, which is a common problem with lower-quality plant milks.

Blind taste tests generally show preferences split fairly evenly between the two brands, with individual preference coming down to subtle flavour differences rather than clear quality gaps.

Price and Availability

Oatly is typically priced at a slight premium over Califia Farms in most markets, though the difference varies by retailer. Both are widely available in supermarkets, health food stores, and online. Oatly has broader coffee shop penetration globally, while Califia has strong distribution across the United States.

Which Should You Choose?

Choose Oatly if: you want the most widely available premium oat milk, prefer a slightly sweeter flavour, or are matching what your favourite coffee shop uses.

Choose Califia if: you prefer a slightly richer texture, want a broader product range from one brand, or find it better priced at your local retailer.
