"Awesome people. Spoke with the owner, Ryan, while picking up my order. Critical Mass will be opening a small store/coffee bar this fall. I am enjoying the coffee I purchased and will be buying more. Plan to check out the coffee bar when it opens."

"Amazing coffee! Tried the Dark Matter whole bean. Great through the espresso machine. Highly recommend!!"

"I met Critical Mass at a trade show style event in Massachusetts and immediately fell in love with both their flavors and their branding and concept. (I'm a science nerd.) I've tasted many of their blends, and they were so tasty that I created a subscription and bought a bunch to give as gifts! Their subscription logistics are fantastic--From the moment the coffee has shipped to the moment it's delivered, I know where it is! I highly recommend Critical Mass for all your coffee needs!"

"This coffee is amazing! We ordered three different kinds (Dark Mass, Costa Rica and Negative Mass) and all of them rocked. The Dark Mass gave me a great buzz, the Costa Rica was super smooth and the Negative Mass has been a nice change for no caffeine but the great flavor of coffee I need. Get on this coffee now!"

"I order their coffee beans in bulk! I've tried a lot of their different roasts, and none have disappointed. Day to day, I'm a decaf drinker, and their Negative Mass decaf roast is the only one I allow in the house. When I do drink a regular coffee, or make an espresso for my partner, I've loved the variety they have to offer in terms of flavor and origins. I also really appreciate their commitment to supporting local farmers, and learning a lot about the regions and people that supply their coffee. I guess you could say I'm stuck with Critical Mass for life!"
