Store any strained Halloween Cocktails Vodka mixture without ice or garnish in a tightly sealed glass bottle. Keep it in the refrigerator below 40°F and use it within 24 hours. After that, the fresh lime starts to lose its bright flavor, while the sage can become too strong. You can also freeze the plain mixture for up to 1 month in a freezer-safe container. Just leave about 1 inch of space at the top since the liquid will expand a little. Don’t freeze crushed ice with the cocktail because it’ll water down the drink as it thaws. This cocktail shouldn’t be reheated. Instead, thaw the frozen mixture overnight in the refrigerator until it’s fully liquid and stays below 40°F. Before serving, shake each four-serving batch with 2 cups of fresh ice for about 10 seconds. Then pour it over new crushed ice and add the fresh blackberry and sage right before serving. Toss any refrigerated mixture if it smells fermented, develops unusual foam, or has cloudy sediment that doesn’t mix back in after a quick 5-second shake.
