Bottles vs. cans: CSU beer study shows amber ales age best in bottles, IPAs fine either way
Fresh beer is the best beer, poured into a frosty glass mug right after production. And, old “skunky” beer is the worst. But a CSU study has shown that the chemical stability of how beer ages is likely dependent on beer style and packaging choice. An amber ale aged better in bottles than in cans during a six-month period, researchers found.
