Hario's new double-wall stainless steel carafes are perfect for keeping your pour-over brews warm for up to 90 minutes, so you can take your time to savor your brew. These thermal servers feature a pour-through lid with a lever-actuated opening, so they keep the heat in until you're ready to pour. The server's opening is designed with V60s in mind, but it can accommodate many other pour-over devices like the Kalita Wave and December Dripper.
When preheated with hot water, this 550 mL carafe (750 mL for the larger size) can keep a fresh brew hot for up to 90 minutes. Our temperature data showed that a fresh, 180 F brew was still hovering around 160 F at 60 minutes, and 140 F at 120 minutes. Compare that to the same drop in about 15 minutes in a standard glass server, and you've got a lot more time to enjoy your brew!
The server is made of stainless steel, the handle and lid are made of polypropylene, the gasket is made of silicone rubber. Hand washes only with mild detergent, do not heat or freeze the server directly.
