Pour Milk First Pour the plant milk into the mug first, then slowly pour in the desired amount of coffee. This will help temper the milk and bring it up to the coffee temp, preventing unwanted curdles in your cup of Joe.
Additionally, why does plant based milk curdle in coffee? Black coffee is more acidic (pH 5 or less) than plant milk (the 'curdle point' of soya milk is around pH 5.5).
