Newsflash: vintage bar carts are back in style. It’s time to head to your attic or basement, dust off the old bar cart and bring it back into use. Or, if you’re new to bar carts, you could check out antique stores or yard sales for a great find!
Once your bar cart is in place, it’s time to clean it up! Read our guide for how to clean off your bar cart, and make sure that the liquor that is already there has not gone bad. It also serves as a handy guide for the shelf life of each bottle you plan to stock. So if you just opened a bottle of creamy coffee liqueur, make sure you plan to serve your guests Irish coffees within the next few months, before it goes bad.

I would have been skeptical except my girlfriend’s parents keep their liquor above the built-in oven for some unknown reason. We had a glass of bourbon out of a 1/4-full bottle that had been getting warmed up a couple times a day and it was so very, very wrong. It wasn’t a lack of subtlety, it wasn’t some evaporation, it was spoiled. So, it can happen. I found this out the hard way.
I think if the temperature is low and the seal on the cap is good, it probably will last just about forever, though.
