Ovalware RJ3 Cold Brew Coffee Maker Review

There are many methods that you can use to ensure that you are making the best possible cup of coffee, and these techniques will depend on what type of coffee you would like to brew. If you are looking to make iced coffee, your methods will differ from someone who wants to make the best espresso.

Arguably one of the best methods for making iced coffee is cold brewing due to its various benefits that are particularly suited for a colder type of coffee. Since the cold brewing process results in coffee that is much less harsh on the palate, you will find that it is the perfect choice for sweeter iced coffees.

Unfortunately, it can be challenging to find a cold brew coffee maker that is worth your money, mainly because they are such simple products. When cold brew coffee makers are so outwardly similar, it makes sense that they would be more difficult to distinguish between, especially when it comes to the details.

Since it is a bit of a challenge to find the right cold brew coffee maker, we will be going over some of the best products in a series of reviews. In today’s case, we are going to be looking at a cold brew iced coffee maker from Ovalware.

In the case of a cold brew coffee maker, the size will not matter as much due to the sheer simplicity of the design of one of these products.

In a cold brew coffee maker, you will find that the size is usually responsible for how much coffee your maker can hold at once. Since cold brew appliances combine the functions of a coffee pot and a coffee machine, a larger cold brew coffee maker will merely be able to hold more coffee at once.
