Expert Reviews


What experts liked

Despite its larger size (the 1.5-liter carafe can hold up to six cups), this cold brew coffee maker can still fit on most refrigerator shelves. The carafe is dishwasher safe.
- Heavy
Customers love the simplicity of this cold brew coffee maker and the fact that it is dishwasher safe. Ovalware provides a 90-day money back guarantee when you purchase this coffee maker and a free ebook for best brewing practices.
Designed to make your beans taste the best, it also makes quite the glass of iced tea. The air tight seal keeps the flavor for up to 2 weeks and protects your brew from those weird fridge odors.

What experts didn't like

Finer grounds may get through the filter. Borosilicate glass isn't the thickest. Filter is required to hold lid securely in place.
- Heavy
The top may not stay tight with the filter in. So while the filter makes a tight seal to the beaker, the top basically just sits in the filter. There is no tension holding it in place and there is no seal.
