Store-bought eggnog that comes pre-spiked? Check the label, but it’s usually around 5% to 10% ABV—think strong beer territory. That’s the “I can still drive a sleigh” level. Homemade, on the other hand, is a wild card because you control the pour. If you add one part spirit to three parts nog, you’re looking at about 20% ABV.
And aged eggnog? Oh, you fancy, huh? When you let that mixture sit in the fridge for weeks (a real thing), the alcohol doesn’t increase, but the flavors meld into something magical. The alcohol stays the same, but your perception of it? Totally off. You’ll swear it’s stronger, but it’s just the spices playing tricks on your tongue.

A Word on “Just a Little Splash”
If you’re the type who says, “I’m only adding a little splash for flavor,” I’ve got news: you’re lying to yourself in the most delicious way. That splash is probably a two-ounce pour. Multiply that by the number of cups you’ll have while wrapping presents, and you’ve got a math problem even Santa can’t solve.
Pro tip: Measure your spirits once—like, actually use a jigger—and you’ll see the difference. One ounce of 80-proof bourbon in a cup of nog gives you roughly a 6% ABV drink. Two ounces? You’re at 12% and rapidly approaching “nap on the couch” territory.
