  "description": "Standard party planning assumes one drink per guest per hour for the first two hours, then tapering off, averaging about 1.5-2 drinks per guest for a typical 3-4 hour party. This calculator estimates total drinks needed and splits them proportionally across wine, beer, and liquor based on typical mixed-crowd preferences.",

    },
    {
      "q": "Why does the rate taper after 2 hours?",
      "a": "Guests drink fastest in the first couple hours and then slow down, so a straight 'one drink per hour for the whole party' formula overestimates total consumption for longer events."

      "q": "How many glasses are in a bottle of wine?",
      "a": "A standard 750ml bottle pours about 5 glasses at a standard 5 oz pour, which is the basis for converting total wine drinks into bottles to buy."

      "q": "Should I plan for non-drinkers too?",
      "a": "Yes — budget separately for sparkling water, soda, and mocktails for the percentage of guests who don't drink alcohol, so nobody is stuck with just water."
