Frequently Asked Questions

What is cold brew coffee?
Cold brew coffee is made by steeping coarse coffee grounds in cold water for 12 to 24 hours. This slow-brewing process produces a smooth, naturally rich coffee concentrate that's less acidic than traditional hot-brewed coffee.

What is the difference between cold brew and iced coffee?
Cold brew is brewed with cold water over many hours, while iced coffee is brewed hot and then cooled over ice. Cold brew typically has a smoother, less acidic flavor and is often prepared as a concentrate that can be diluted before serving.

What grind size should I use for cold brew?
A coarse coffee grind is recommended for cold brew. Coarser grounds allow for even extraction while helping reduce sediment in the finished coffee.

How long should I brew cold brew coffee?
Most cold brew recipes recommend brewing for 12 to 24 hours in the refrigerator. Longer brew times generally create a stronger concentrate.

How long does homemade cold brew last?
When stored in the airtight Ovalware Cold Brew Maker and refrigerated, cold brew concentrate can stay fresh for up to two weeks, making it perfect for meal prep and busy mornings.

Can I use flavored coffee for cold brew?
Absolutely. Flavored coffees like our Southern Pecan, Dark Chocolate, and Vermont Maple Pecan create delicious cold brew with naturally smooth flavor and aroma.

Do I need paper filters?
No. The Ovalware Cold Brew Maker includes a reusable stainless steel mesh filter, eliminating the need for disposable paper filters while allowing more of the coffee's natural oils and flavors to remain in your cup.

Is the carafe made from glass?
Yes. The brewer features premium borosilicate glass, chosen for its durability, clarity, and resistance to temperature changes.

Can I brew tea in the Ovalware Cold Brew Maker?
Yes. While designed primarily for coffee, the brewer can also be used to prepare cold-brewed loose-leaf tea. For traditional hot tea brewing, we recommend our Ethoz Glass Tea Brewer.

The Ovalware Airtight Cold Brew Coffee Maker (RJ3) is ideal for anyone searching for a cold-brew coffee maker, glass cold-brew brewer, airtight cold-brew pitcher, reusable cold-brew filter, or home cold-brew system. Its premium borosilicate glass construction, reusable stainless steel filter, and airtight storage design make it an excellent choice for brewing smooth, low-acid cold brew coffee at home.
