When gazing upon a lovely pour of a terrific beer, what elements are most important?
A lovely color – certainly.
A terrific aroma and flavor profile – well, obviously.
And those lovely little bubbles due to carbonation – indeed… well, that might be an issue.
According to experts, the craft beer and brewing industry might be hit by a shortage of those bubbles due to a lack of CO2. Just how did this happen? And is this a long-term problem?
Tim Kraft, Associate Professor of Operations and Supply Chain Management at NC State University believes there are myriad underlying reasons behind the industry’s CO2 shortage.
“There are a number of factors putting pressure on the supply of carbon dioxide and causing prices to spike,” Kraft said.
“CO2 is produced as a byproduct of processes such as ethanol and ammonia production, and many of these facilities are going through scheduled maintenance this fall, limiting their output of CO2.”
