What is the consequence of not storing Madeira and Sherry upright?

• A. The cork could be eroded by alcohol.
• B. The wine will turn sour.
• C. The bottle will crack.
• D. The color will fade.

Answer: (A)

Madeira and Sherry are fortified wines with relatively high alcohol content, and the cork plays a crucial role in keeping the bottle sealed over time. When bottles are not stored upright, the wine sits against the cork longer, and the alcohol can gradually erode or deteriorate the cork. A compromised cork can lose its seal, allowing air in and potentially leading to leakage or oxidation, which is why upright storage helps preserve the integrity of the seal. The other outcomes listed aren’t primarily driven by storage orientation: souring, a cracked bottle, or fading color aren’t the direct risks associated with not storing these wines upright.
