Quick Answer

Plant milk is a dairy-free alternative made from nuts, seeds, or grains like oats and almonds. Salter’s guide highlights its nutritional benefits for vegan and lactose-intolerant lifestyles. Making plant milk at home with a Salter Plant Milk Maker is significantly more affordable than store-bought options, reduces plastic waste, and ensures your drink is free from unnecessary additives.

Introduction

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.

Pros

  • Massive Cost Savings: Homemade oat milk is roughly 98% cheaper than store-bought versions.
  • Eco-Friendly: Making your own eliminates the need for plastic-lined cartons and reduces waste.
  • Dietary Friendly: Naturally free from lactose and animal products; perfect for vegans.
  • Customisable Flavor: You can adjust the sweetness, thickness, and creaminess to your exact preference.

Cons

  • Ingredient Knowledge: Store-bought versions often contain hidden "fillers" like gums and oils.
  • Short Shelf Life: Without preservatives, homemade milk typically needs to be consumed within a few days.
  • Natural Separation: Homemade milk may settle or separate (just give it a quick shake!).
  • Equipment Needed: Achieving the best savings and texture requires a dedicated plant milk maker.

Which plant milk is best?

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.

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.

Frequently Asked Questions

Is it cheaper to make your own plant milk at home?
Yes, making plant milk at home is significantly more affordable than buying it at the supermarket. For example, using a machine like the Salter Plant Milk Maker, homemade oat milk costs as little as £0.03 per litre, compared to the average shop-bought price of £1.76. This represents a saving of £1.73 per litre, allowing the equipment to pay for itself quickly.
Which plant milk is best for coffee and frothing?
Oat milk is widely considered the best choice for coffee because it mimics the creaminess of dairy and froths exceptionally well for lattes and flat whites. If you prefer a richer, more indulgent texture for hot chocolates or specialty drinks, cashew milk is an excellent alternative due to its high fat content and natural creaminess.
How can I ensure my homemade plant milk has enough calcium?
While store-bought milks are often artificially fortified, you can boost the nutrition of homemade milk naturally. Choosing calcium-dense ingredients like almonds or macadamia nuts is a great start. You can also add seeds, such as flax seeds, into your plant milk maker during the blending process to increase the mineral content without affecting the flavor.
