Is it Rude to Ask the Somm to Change the Temperature of the Wine I Ordered?

When it comes to wine temperature, there are a handful of rules. Some are quick tips for when you’re in a pinch like the easy-to-remember 20 minute rule, while others are more nuanced serving guidelines that map out the proper temperature for each style down to the exact degree. Though these time-tested recommendations might suggest that tannic, heavier red wines like Cabernet Sauvignon need a little warmth for the bold flavors to pop, while colder temperatures can make lighter-bodied wines like Gamay zing with acidity, temperature — like many things in wine — ultimately comes down to personal preference.
