Technical Specification: Wedding Alcohol Consumption Calculator

1. Overview

A browser-based, client-side application designed to help users calculate the volume of alcohol (beer, wine, spirits) and non-alcoholic beverages required for a wedding reception. The app aims to prevent over-purchasing and under-stocking.

2. Feature List

  • Dynamic Inputs: Users define guest count, event duration (hours), and a "Guest Profile" slider (adjusting the ratio of moderate vs. heavy drinkers).
  • Category Breakdown: Results are displayed in four categories: Beer, Wine, Spirits, and Non-Alcoholic (Soft Drinks/Water).
  • Ratio Customizer: Advanced settings to adjust the % of consumption per category (e.g., 50% Beer, 30% Wine, 20% Spirits).
  • Shopping List Generator: A clean text-based breakdown of total units needed (e.g., "24 bottles of wine," "4 kegs of beer").
  • Safety & Liability Reminders: Automated prompts advising the user to provide equal amounts of water and soft drinks, and suggesting professional bartenders for liability management.

3. UI Layout

  • Header: A clean, centered title "Wedding Beverage Planner" with a subtle, elegant icon.
  • Main Tool Area (Two-Column Layout on Desktop, Single Column on Mobile):
    • Left Column (Controls): Range sliders for duration, guest count, and alcohol type ratios.
    • Right Column (Visualization): A real-time updating list of estimated units, paired with simple, elegant CSS-animated bar graphs showing the distribution of drinks.
  • Summary Section: A prominent bottom section showing the "Total Estimated Budget Range" and a "Print/Copy Shopping List" button.

4. Design & Aesthetics

  • Color Palette: Professional light-mode aesthetic.
    • Primary: #4A6741 (Deep Sage) for actionable elements.
    • Background: #F9FAFB (Soft Off-White).
    • Typography: Inter or System-UI sans-serif, dark gray #1F2937 for readability.
    • Accents: Subtle shadow effects (shadow-md, shadow-lg) on input cards.
  • Animations: Use CSS transitions (ease-in-out) for all slider inputs. When calculations update, use a subtle fade-in effect on the numerical results.

5. Technical Directives

  • Single File: All HTML, CSS, and Vanilla JS must be inside one file.
  • Zero Storage: Do NOT use localStorage, sessionStorage, or cookies. Use local variables for all calculations.
  • No Popups: Do not use alert(), prompt(). All notifications (e.g., "Copied to clipboard") must be custom-built HTML toasts.
  • External Libraries: Use Tailwind CSS via CDN for styling. Use a standard icon library (e.g., Lucide-icons) via CDN.
  • Iframe Ready: All code must function within a sandboxed iframe. Ensure no calls to top-level browser navigation are made.

Frequently Asked Questions

Everything you need to know about using this application.

How does this wedding alcohol calculator determine the drink quantities?

This tool utilizes industry-standard event planning heuristics, specifically the 'one drink per person per hour' rule. By taking your total guest count and the duration of the event, the calculator determines the baseline volume of alcohol required for the reception. It further refines these numbers by allowing you to categorize your guests by drinking habits, such as light, moderate, or heavy, and applies a standard distribution ratio across beer, wine, and liquor options to provide a balanced shopping list.

Can I use this calculator for events other than weddings?

Absolutely. While this tool is optimized for wedding reception planning, the underlying logic applies perfectly to any large gathering, including anniversaries, milestone birthdays, or corporate holiday parties. The flexibility of the input variables, such as duration and guest demographics, makes it a robust choice for any event where you need to manage a bar budget and logistics efficiently without complex spreadsheets.

Is my event data saved or stored on your servers?

No, this application is designed with strict privacy and security in mind. It operates entirely as a client-side, in-memory application within your browser. We do not use cookies, local storage, or server-side databases. When you close the browser tab, all calculated data and inputs are immediately purged. This ensures your planning data remains completely private and unreachable by third parties.

How accurate is the beverage estimation compared to professional catering standards?

The estimates provided are based on conservative industry averages that help hosts avoid running out of beverages while minimizing excessive waste. These guidelines account for common social dynamics and consumption patterns at social events. However, it is always recommended to use these figures as a starting point. We advise cross-referencing these results with your specific venue policies and any known guest preferences to ensure complete satisfaction for your event.
