All Mastermind products come with a lifetime warranty on the brewer functions. If a part of the brewer is defective, we will issue a replacement. The warranty does not cover cosmetic damage such as dents, dings, or scratches.
Our policy lasts 30 days. If 30 days have gone by since your purchase, unfortunately we can’t offer you a refund or exchange.
To be eligible for a return, your item may be used or unused, but not damaged. It must also be in the original packaging.
We do not accept returns on coffee.
The resulting boldest possible concentrate will have 6.8 parts water to 1 part coffee, which is considered extremely bold in the world of cold brew.
Mastermind is all about perfection. We want you to love coffee as much as we do. And while we know that cold brew is the best coffee you can get, it isn’t as easy as that Keurig you have sitting on the counter. That is why we are working hard every day to perfect products that will really innovate within the cold brew marketplace and fit into the fast-paced, on-the-go lifestyle of every working class American.
