Overview
An electric cold brew maker that spins coffee grounds through water to produce cold brew in about 15 to 30 minutes, instead of the usual 12 to 24 hour steep.
The glass carafe and grounds basket sit on a base that spins water in a cyclonic motion, pulling flavor out of the grounds without exposing them to heat.
- Cold brew in about 15 to 30 minutes vs 12 to 24 hour traditional steep
- Cyclonic spin extracts flavor without exposing grounds to heat
- Glass carafe with magnetic coffee basket
- Adjustable brew speed and spin time for strength
Who it's for
Fits coffee drinkers who want cold brew the same day rather than waiting overnight, including those running more than one unit for extra batches. Traditionalists who prize the smoothness of a slow overnight steep may prefer that method instead.
Pros and cons
- Cold brew ready in about 15 to 30 minutes
- No high heat exposure, so less bitter
- Magnetic coffee basket simplifies grounds handling
- Run two units at once for double batches
- Glass carafe reported thin and prone to breaking
- Grounds cleanup can be messy
- A few found flavor less smooth than overnight steep
Performance notes
Because grounds are never exposed to high heat, the flavor comes out without the bitterness of hot brewing.

Frequently asked questions
Is the glass carafe durable?
One long-term reviewer noted the glass is fairly thin and broke a carafe after continued use, so it should be handled carefully.
