How Does Oat Milk Change the Milk to Coffee Ratio in a Latte?
Oat milk works in a latte because it steams and pours in a similar way to dairy milk, but it tastes different. It brings a natural sweetness from oats, a lighter body, and no lactose, which suits people who are lactose intolerant, vegetarian, or allergic to milk protein. Dairy milk adds a richer, creamier mouthfeel.
The milk to coffee ratio latte drinkers use stays roughly the same whether the milk is dairy or oat, commonly around one part espresso to three or four parts milk, but oat milk foams faster and thins sooner, so less steam time helps. Different oat milk brands vary in fat and added oil, which changes how well the drink holds together.
