Change isn’t necessarily innovation. New Belgium recently changed its iconic Fat Tire recipe such that it is a different beer. Different packaging too. Fat Tire was always a little too much in the sweet side for me. The new Tire is less hoppy, therefore a little sweeter, seems like more carbonated, and lighter in colir. I think it is trying to muscle in on all the brewed seltzer products that have increasing market share.I didn't use to think that innovation was all that important in brewing beer, which we have done since basically forever. But a former IU grad school chemist classmate of mine left a pharma job years ago to go into brewing. I still see him every now and then. He's now in charge of R&D for a craft brewery. He regularly goes to beer shows to see what's hot. I guess he not only has to come up with new flavors but also is always learning about tweaks to any parts of the process that affect product quality in a positive way. From variations in hops breeding and sourcing, to capping technology, to better exclusion of light and air, and other factors.
Meanwhile, other New Belgium products keep chugging along. I like their 1554 the best.
