FAQ - Milk Frother General Questions

For better result

1. Use fresh refrigerated whole milk (fat>3%) for better froth richness. Non-dairy milk does not produce as much froth as dairy milk.
2. Always use cold (about 39-43F/4-6℃) and fresh milk.
3. Always fill the milk jug between the MIN and MAX level markings.
4. Pour the frothed milk as soon as possible for the best foam quality.

Frothed milk should not be reheated to prevent the overheat protection from activating.

For frothing non-dairy milk

1. We recommend using barista types of milk over plant milk for richer milk foam. Plant-based milk generally does not foam as well as whole dairy milk, the froth result can not be guaranteed.
2. Generally, the foam is richer if there's a higher concentration of protein, the froth thickness goes down like this: Soy milk> Almond milk>Coconut milk>Rice milk >Cashew milk >Oat milk.
