Price and rating as shown on Amazon when we collected them. Both change.
The ovalware RJ3 is our number five cold brew maker pick for September 2026 and the premium compact glass brewer in this guide. Its 1.0 litre carafe is extra-thick borosilicate glass, the removable filter is an 18/8 dual mesh design and the airtight silicone seal keeps concentrate fresh for up to two weeks. The listing records 12,733 ratings at 4.5.
Honesty note: the capacity spec prints 964 g where a litre figure belongs, flagged as listed. Everything on this page comes from the Amazon listing rather than our own testing.
