Master your Technique.

Mastermind believes that making coffee is more of an art than a science. The fill lines help people make a great coffee quickly, but ultimately you should tweak for your own taste buds.

Frequently Asked Questions

Built to Go.

Pack your brewer and some freshly ground coffee into your suitcase. Brewing amazing craft coffee has never been easier. Just make sure you keep it level - our magnetic slider will leak if the brewer is left on its side.

Hot Coffee in only 2.5 min.

We designed your brewer to make hot coffee as well. The process is the same as cold brewing, just use near-boiling water and gently swirl the brewer for 2.5 minutes. Once ready, remove the filter and enjoy. It is important to remove the filter after hot brews to avoid a bitter flavor from over-extraction.

Brew Tea.

Fill the filter with 1.5 TBSP of Tea, or up to the bottom fill line marked with a tea leaf.
Pour Boiling Water to Brewer fill line.
Steep 2.5 minutes.

Get Creative with Fruit Infusions.

Fill filter with fresh fruit.
Infuse for several hours, or to taste.

TAKE CARE OF YOUR GEAR

Mastermind's Kōld Brewer looks amazing, and the 3XX cold-rolled stainless steel is strong. The paint, however, is delicate. Avoid tossing the brewer around and putting it into contact with other hard materials. Store the filter in the brewer when not in use to prevent denting.

All components of the brewer are dishwasher safe.

If you have issues, we're just a message away! All Mastermind products feature a lifetime warranty.
