How does storage temperature affect shelf life of hops?

• A. Warmer temperatures accelerate aroma loss and bitterness degradation; cooler temps preserve hop quality longer.
• B. Warmer temperatures improve hop aroma
• C. Temperature has no effect on hops
• D. Cooler temps degrade hop freshness

Answer: (A)

Storage temperature governs how fast the compounds in hops react and escape. The essential oils that give hops their aroma are volatile and prone to loss when heat is present; warmer storage speeds up evaporation and oxidation, leading to quicker aroma fade and some degradation of character, including bitterness stability over time. Cooling slows these processes, so aroma, flavor, and overall hop quality are preserved longer. That’s why refrigeration or freezing is recommended for long-term hop storage. The other statements aren’t accurate because heat doesn’t enhance aroma, temperature does affect hop chemistry, and cooling doesn’t harm freshness—it helps maintain it.
