How to Achieve the Perfect Frothed Milk
Why do certain types of milk froth better than others?
• The key factor in achieving good froth is using fresh, cold milk.
• Fresh milk should be consumed within 10 days of purchase and if using the milk for frothing,
use within 5 days of purchase to get the best foam.
• Milk should be very cold. Use milk that has been taken directly from the refrigerator and start
frothing immediately.
• Organic and lactose free milks are ultra-pasteurized and therefore the proteins in the milk are
destroyed and do not support the milk bubbles in the foam. Do not use these types of milk
when trying to achieve a thick froth; these milks work better for lattes.
• Milk should be kept away from light. It is better to buy milk in opaque containers rather than
clear containers.
• Do not leave milk on the counter after use as this can affect the freshness of the milk. Always
put milk back into refrigerator when done using.
• Always wash your milk container after use. NEVER re-steam milk once it has been heated.
Only steam the amount of milk you are going to use.
• Never add fresh milk to milk that has already been steamed as bacteria can grow.
• Never pour hot milk over ice as bacteria can grow.
• If you have a Jura Cool Control, clean the milk pitcher at least once a week and every time
you add fresh milk to the pitcher.
The science of frothing milk:
• Proteins and fats in milk are responsible for how well the milk with be frothed.
• The act of steaming milk is essentially forcing air into the milk while increasing the milk’s
temperature.
• The protein in the milk is what stabilizes the entrapped air and forms bubbles and froth.
• If the milk has too much fat, the protein cannot support the bubbles and the froth will be flat.
• Fresh milk isn’t always consistent and has many other factors that can alter the taste such as:
what the cow has been fed, type of cow, the pasteurization process, how the milk was stored
before it was purchased, etc. All these factors attribute to the variation of fresh milk and its
ability to consistently produce froth.
• If your milk is not frothing the way you like, please try another type of milk as described
above.
