I foamed with various espresso machines milk; including cheap no-name machines, but also really expensive equipment (such as company law). Fact: All of these devices foam no longer reasonable to sooner or later on. Producers speak out himself: "The weather does not allow for better quality."; "You take the wrong milk" However, taking the milk frother Severin, so you can run any type of milk used in any weather ... Normal milk is indeed more difficult to foam, as long-life milk or low-fat UHT milk, but also prepares no problems. Even if the unit is no longer working, so you can invest EUR 4 again and must not equal a new espresso machine to buy for frothing. If you like drinking hot cappuccino, must bear in mind that the milk must be heated before, which does not present any special effort by the steam in an espresso machine. Conclusion: you!
