Buy a digital thermometer. They cost $10 and will save you from dozens of lukewarm disasters. Stick it in the bottle for ten seconds, and you’ll know instantly if you need to chill or warm.
Use a wine sleeve. If you’re serving outdoors, pop an insulated sleeve on the bottle. It keeps the wine at a consistent temperature without turning it into ice. Your friends will think you’re a pro.
Don’t be afraid to experiment. Taste your Chardonnay halfway through the bottle. As it warms, the flavors change. The first glass might be tight and mineral; the third glass could be lush and tropical. That’s the magic of temperature.
