Homemade vs Store-Bought Oat Milk — Which is Better?

Walk into any Norwegian supermarket and you'll find a wall of oat milk cartons. Oatly, Alpro, Eldorado — they all promise healthy, plant-based goodness. But is store-bought oat milk really as healthy as it looks? And how does it compare to making your own at home?

We put them head to head so you don't have to.

🥛 What's Actually in Store-Bought Oat Milk?

Flip a carton of store-bought oat milk and you'll typically find: water, oats (around 10%), rapeseed oil, salt, and a list of additives — stabilisers, emulsifiers, vitamins, and sometimes added sugar. It's not exactly the pure, wholesome drink the marketing suggests.

The oil is added to mimic the creaminess of dairy. The stabilisers stop it from separating on the shelf. And the vitamins? Added back in because processing removes the natural ones.

🌿 What's in Homemade Oat Milk?

Oats. Water. That's it — if you want it that way. You control every single ingredient. No oils, no stabilisers, no additives. Just pure oat milk, made fresh in minutes.

📊 The Comparison

Additives Yes None
Added oils Usually yes No
Cost per litre 40–80 NOK 5–10 NOK
Freshness Weeks old Made today
Taste Consistent Fresh & natural
Environmental impact Packaging waste Zero packaging

💰 The Cost Difference is Shocking

A litre of store-bought oat milk costs between 40 and 80 NOK. A bag of oats costs around 20–30 NOK and makes 8–10 litres of homemade oat milk. That's less than 5 NOK per litre — a saving of up to 75 NOK every single litre.

If your household uses 2 litres per week, you could save over 6,000 NOK per year just by switching to homemade.

⏱️ But Isn't It Time-Consuming?

This is the biggest myth. With a modern plant-based milk machine, making oat milk takes less than 3 minutes. Add oats, add water, press start. The machine blends, heats, and even cleans itself. There's no straining, no mess, no effort.

Compare that to driving to the supermarket, finding parking, and queuing at the checkout.

🏆 The Verdict

Homemade oat milk wins on every level — ingredients, cost, freshness, taste, and environmental impact. The only reason people still buy store-bought is convenience. But with the right machine, homemade is just as convenient.
