Overview

OneDream's 1 gallon cold brew maker pairs a wide-mouth glass jar with a stainless steel filter basket and a spigot, sized for brewing a week's worth of coffee, tea, or infused water in the fridge at once.

This is a manual steeping jar, not a machine, so there is no timer or pump involved; results depend on grind size and steep time the way any cold brew does. The silicone gasket at the spigot and the flip-up vent lid are aimed at two common complaints with glass cold brew jars: cracked spigot seats during assembly and lids that pop off under pressure when pouring. A silicone base mat and spigot cover round out the physical protection for fridge and counter use.

  • 1 gallon wide-mouth glass jar
  • Stainless steel removable filter
  • Flip-up silicone vent lid
  • Silicone spigot cover and base mat

Who it's for

Fits anyone brewing cold brew, iced tea, or sun tea by the batch for a household or small office, rather than a single mug at a time. Not a fit for anyone wanting a pump-driven or electric brewer, or a countertop drip system.

Pros and cons

Pros
  • Full 1 gallon capacity for weekly batches
  • Removable steel filter keeps grounds contained
  • Vent lid designed to reduce lid removal
  • Silicone base mat and spigot cover included
Cons
  • Manual steeping only, no timer or pump
  • Glass jar requires careful handling despite padding

Performance notes

Coffee grounds sit in the removable stainless steel filter basket inside the glass jar while cold water steeps around them, the standard method for this style of brewer. The flip-up silicone vent on the lid is meant to be opened before using the spigot, which lets air into the jar and should keep the pour smooth without loosening the whole lid. The I-shaped silicone gasket at the spigot mount is a manufacturing detail aimed at reducing metal-to-glass contact during assembly, which is where these glass jars typically crack.

Frequently asked questions

Can the OneDream cold brew maker be used for more than coffee?

Yes, the same gallon jar and spigot setup works for iced tea, sun tea, lemonade, and other steeped or infused drinks, not just cold brew coffee.

Does the spigot on this jar require assembly?

Yes, the spigot is fitted into the glass with an I-shaped silicone gasket meant to cushion the metal-to-glass contact during installation.

Is the filter in the OneDream jar removable for cleaning?

Yes, the stainless steel filter basket lifts out of the jar, and the wide mouth of the jar allows hand washing.
