A traveler can steep grounds in this stainless vacuum insulated brewer and carry it afterward. The reusable filter holds the grounds and the carafe is leakproof.
The insulated carafe lets the brew chill in transit, and the set includes a mug. The listing mentions a European coffee festival award. The limit is hand washing and the absence of any listed warranty.
Who it's for
Commuters and travelers who brew cold coffee away from home. Households brewing big batches need a larger pitcher.

Coarse grounds steep in cold water inside the filter over time, then the brew is poured from the insulated carafe. The vacuum wall slows warming. Grind size and steep time decide strength.
