Ice. This may seem like a no-brainer, but it’s a real bummer when you find yourself trying to make a drink without ice on hand. Sure, you can always go out and buy ice in a pinch, but always keeping enough on hand in your freezer is the smartest way to make sure you don’t run out. Last but not least, it’s time to stock your bar with your favorite alcohol. Gin? Vodka? Tequila? It’s up to you because you’re the bartender now.
