To limit oxidation while maintaining beer quality, what is the optimal temperature range for beer storage?

1. 25-35°F

2. 35-45°F

3. 45-55°F

4. 55-65°F

The correct answer is: 35-45°F

The optimal temperature range for beer storage to limit oxidation while maintaining quality is indeed between 35-45°F. This range is cool enough to slow down chemical reactions, including oxidation, which can negatively impact the beer’s flavor and aroma. Keeping beer within this temperature range not only preserves the beer's intended character but also ensures that it remains fresh for a longer period. A temperature that is too low, such as in the 25-35°F range, may lead to unwanted effects like sluggish yeast and potential crystal formation in certain styles, which can alter the beer's texture and mouthfeel. On the other hand, storing beer at 45-55°F or higher can accelerate oxidation and degradation of flavor compounds, diminishing the overall quality of the beer over time. Thus, maintaining the temperature within the 35-45°F range strikes a balance between preventing oxidation and allowing for the optimal expression of the beer's flavors.
