The Asobu Coldbrew portable coffee brewer lets you make and take cold brew coffee in the same container. The coffee drips into an insulated and spillproof carafe that will keep coffee cold (or hot!) for hours. It can also be used with loose leaf tea.
Portable espresso machines often use pumps or screws to push water through ground coffee. The upcoming Leverpresso uses a simpler lever mechanism that still lets you control your coffee’s taste. It also lets you make up to two shots of espresso in one go.
