Idaho State Liquor Division - Responsible Party PlanningPlanning a home party? Let us help you plan and pull off a truly memorable and responsible occasion, whether you’re hosting a cocktail party, martini night, or family celebration.

For starters, you only need a few basic bartending items to look like a professional (items may vary depending on what you plan to serve): bottle opener, corkscrew, cocktail shaker, bar strainer, -1.5ounce jigger, ice bucket, ice tongs, stirrers, coasters, and cocktail napkins. Having the right glasses available is important, but you don’t need a special glass for each drink. Two basic shapes are adaptable for most drinks: rocks glasses (with or without a stem) and basic wine glasses.

When planning a party, deciding how much wine or spirits to buy can be a daunting task. Follow this simple formula to ensure a successful party. First, determine the number of guests that will be attending. Multiply that number by the number of hours you think the party will last. This will give you the number of servings you’ll need. Use the following chart to determine approximately how many bottles of liquor and wine to purchase.
