The history of brewing is filled with innovations and adaptations, but some traditions hold special significance. One such tradition is the use of glass-lined tanks for fermentation, a practice employed by Rolling Rock Brewery for generations. However, in 2015, Anheuser-Busch abruptly discontinued this centuries-old process.
Was Rolling Rock truly the last beer to be brewed in glass-lined tanks? The answer is surprisingly complex.
The Evolution of Rolling Rock’s Fermentation
For over a century, Rolling Rock clung to the traditional glass-lined fermentation tanks. This unique approach yielded a distinct flavor and texture, considered by many to be superior. However, the process was expensive and laborious.
In the 2000s, Anheuser-Busch, which had acquired Rolling Rock in 1985, began exploring cost-effective alternatives. Experiments with stainless steel fermentation tanks yielded inconsistent results. Consumers voiced their dissatisfaction with the altered taste.
The Sudden Change and Aftermath
In 2015, despite public outcry, Anheuser-Busch abruptly stopped brewing bottled Rolling Rock in its traditional glass-lined tanks. The company claimed the shift was due to logistical challenges, but many suspected it was a cost-driven decision.
The Mystery of the Remaining Inventory
Despite the official announcement, some suggest that Rolling Rock may still be brewed in glass-lined tanks. Allegedly, the company continues to produce limited batches for special releases or promotional events. Anheuser-Busch remains tight-lipped about any such practice.
Conclusion
The fate of glass-lined fermentation in the brewing industry remains uncertain. While Rolling Rock was undoubtedly the most prominent casualty in this transition, other small-batch breweries may still utilize this traditional technique. The question of whether this unique flavor will disappear entirely or resurge in the future remains unanswered.
