One of the greatest things a brewer can do to improve his beer is manage the fermentation temperature. This is far more important than using fancy fermentors or even all-grain brewing.

I thought it would take me years before I was able to afford the equipment for lagering, BrewJacket made this a reality within a few months... The support is always responsive, and always willing to go above and beyond to make sure you're happy. I have three BrewJackets now- and they're great!

Brewjacket has been revolutionary to my brewing. With about 100 batches in my history, this device has, for the first time, enabled me to prevent fermentation temperatures from hitting the zones that produce off flavors in the warmer months. Secondly, its enabled me to keep the fermenters in one location in the garage - outside of our living room and light protected so the sunlight problems are not an issue. Lastly, as a result of this, I am able to pick any style of beer, at any time of the year to brew. I've greatly enjoyed the personal interaction with the team at BrewJacket and their rapid responses to fix my concerns without hesitation. I greatly look forward to many new brews with precision control.
