What is plant milk?

Plant milk (or plant-based milk) is a dairy-free alternative to cow’s milk, made from plant-based ingredients such as nuts, grains and seeds. Popular examples include oat milk, almond milk, cashew milk and coconut milk all offering a unique taste, texture, and nutritional profile.

These milks are entirely free from animal products, making them suitable for vegan, lactose-intolerant, or health-conscious individuals. They’re often used in everything from coffee and cereal to baking, smoothies, and sauces.



Which plant milk is best?

With so many dairy-free milk options to choose from, it can be hard to know which one is right for you. Whether you're looking for the healthiest plant milk, the most sustainable dairy-free milk, or simply something that tastes great in your morning coffee. With the Salter Plant-Milk Maker, you’re not limited to trying just one! However, if you want to check out which dairy-free milk you’d like to try first, here’s a quick guide to help you choose the best plant-based milk for your needs.


Which plant milk is the most affordable?

When it comes to saving money, homemade plant-based milk is by far the most affordable option. Shop-bought oat milk typically costs around £1.76 per litre, but when made using the Salter Plant Milk Maker, it costs as little as £0.03 per litre, saving a impressive £1.73 every time! Similarly, almond milk usually costs around £1.91 per litre, but you can make it yourself for just £0.46.

With savings like these, the cost of the Salter Plant Milk Maker pays for itself in no time! Plus, that’s before you factor in the added benefits of making your own dairy-free milk: no plastic cartons, no unnecessary additives, and total control over your plant-based ingredients.


What is the healthiest plant milk?

Many consider unsweetened almond milk or homemade oat milk to be the healthiest plant-based milk options. They’re both low in calories and sugar, and when made at home with a nut milk maker like the Salter Plant Milk Maker, you can avoid gums, oils, and preservatives completely. However, all plant milks have different nutritious profiles and therefore the healthiest plant-based milk is entirely dependent on individual nutritional needs.


Which plant milk is best for coffee?

Oat milk is often considered the favourite of baristas due to its naturally creamy texture, frothing ability, and mild, slightly sweet flavour that pairs perfectly with everything from lattes to flat whites. That said, cashew milk offers an even richer, creamier texture that’s ideal for indulgent drinks like hot chocolate, while coconut milk, similarly to almond milk, bring a distinctive flavour that some coffee lovers swear by.


Which plant milk has the most calcium?

Some store-bought dairy-free milks are fortified with calcium, but if you’re making your own dairy-free milk in a plant milk maker, macadamia milk and almond milk are good naturally calcium dense option. You can also increase calcium levels in homemade plant-milk by adding seeds (such as flax seeds) when using Salter’s nut milk maker.


Is oat milk good for you?

Oat milk is naturally high in fibre and low in saturated fat, a considerable benefit for many. However, many store-bought plant milks also contain added oils, sugars, and more. While these additives can offer benefits, such as added vitamins or improved texture, they’re not always necessary or ideal. By making your own plant-based milk, whether you choose oats, almonds or cashews with a machine like the Salter Plant Milk Maker, you stay in full control of what goes into your drink, tailoring it to your individual nutritional needs and preferences.
