Cold brew fans know the process for making this type of coffee is completely different from hot coffee, and can be time-consuming to do at home. But the Cumulus cold brew coffee machine is designed to make only single-cup cold brew, nitro, and cold espresso in a process as easy as using a Keurig -- and it's the only way to make nitro cold brew at home.

The machine usually comes at a high price point of $695. But ahead of Mother's Day, it's 20% off with code MOTHERSDAY20, dropping the price to $556 and making it a great time to buy if you're in the market for a high-end at-home cold brew machine.

I tried out the Cumulus cold brew machine at home, and was impressed by the design -- it's tall, but has a slim, stylish profile, and is extremely simple to use. You pop a proprietary pod filled with coffee concentrate into the cylinder at the top, and select from three options: still cold brew, nitro cold brew, or cold espresso. When you first add water to the machine, it takes about 15 minutes to cool it down. After that cooling period, it brews in about a minute, so if you fill it up before you go to bed at night, it'll be ready for you to instantly brew when you're ready for coffee.
