Countertop models of milk steamers and frothing machines are more efficient than frothing wands at both steaming and creating velvety, frothy milk. Some even come with attachments that allow for producing dense or loose froth appropriate for cappuccinos or lattes.
While frothing wands tend to be cheaper than steaming frothing machines, some wands do not heat milk, which means milk must be heated separately beforehand. Several models of frothing machines are able to froth hot and cold milk. Frothing machines tend to produce milk foam that is generally richer and denser than frothing wands, which typically yield very light, bubbly froth. Some frothing machines also offer the option of selecting the precise temperature to which milk can be steamed.
