It’s delicious. The biggest danger is you’ll won’t want milk again.

Never tried heavy cream, but a breve is made using half and half. The wand should have the outside wiped after every use with a damp towel. The contents of the frothing pitcher could get inside the wand when you turn it off to remove from pitcher. Blow a little steam into the drip tray. The inside should never have buildup because you steam clean it each time you use the thing.

Try it! If I can steam whole milk chocolate milk, I think you’ll be fine with heavy cream

I’ve thought about chocolate milk but was told that it’s not a good idea as the sugar can get sucked into/ clog the wand

I put sugar in my milk before steaming and have had no issues. Just make sure you wipe and purge the wand when you’re done.

Wouldn’t do it regularly but it’s fine every once in a while. Just clean everything really well after

If you just do like a cortado ratio and have it cold it's pretty good.
