Beer is becoming an increasingly precious resource due to a CO2 shortage | NBWA: America's Beer and Beverage Distributors

The ongoing carbon dioxide shortage may be to blame if you’re noticing less of your favorite brews on store shelves or a price increase on your go-to six-pack. The supply first took a hit in 2020 when gasoline demand was low; CO2 is the byproduct of ethanol and when people were staying at home instead of filling up their tanks and hitting the road, less ethanol (and by extension, less CO2) was produced. Now, in 2022, a combination of increased gas prices, increased seasonal demand and contamination to a key supplier are all making CO2 more expensive and harder to come by.
