Frequently asked
?
Which plant milk is healthiest?
Soy milk is most nutritionally similar to cow's milk (protein, calcium when fortified). Oat milk has more carbohydrates. For pure protein value: soy. For bone health: choose any fortified variant. For sustainability: oat is generally best.
?
Why does almond milk froth poorly?
Almond milk is mostly water with little fat or protein — the proteins needed to form stable foam bubbles. Barista-formula almond milks add extra stabilisers that improve frothing but add cost.
