Milk frother

Although created in Italy, the espresso machine and steam wands were exported internationally to other countries, and frothed milk was introduced around the world.

In the 1950s, espresso machines that were once native to Italy and their production of coffee were exported overseas to Mediterranean and British markets.

[2] Cappuccinos became widely popular in Britain because of the exotic nature of milk froth and the technology used to make it.

[4] Contrastingly, frothing skim milk, which has significantly less amounts of fats and protein, will produce a lighter and thinner foam.

Casein molecules (a type of protein) form the molecular structure micelle, which get broken up when air from a milk frother is introduced.

[4] A manual frother consists of a perforated mesh plunger in a cylinder, similar to a French press, which is moved up and down by hand.

[6] A battery-powered milk frother wand is an electric mixer with a small, circular whisk.

Electric frothers are fast and provide high-quality foam, and may have large enough capacity to prepare multiple beverages.
