How much ice do I need for a party?
General rule: 1 pound of ice per guest per hour for drinking. Add 1 pound per guest for cooling food/drinks. For a 4-hour party with 20 guests: 20 guests × 4 hours = 80 lbs for drinks + 20 lbs for cooling = 100 lbs total. Summer/outdoor parties need 1.5x this amount. Always round up - melted ice is better than running out.
What size ice cubes should I use?
Standard cubes (1 inch) work for most drinks and melt at moderate rate. Large cubes (2 inch) melt slower - ideal for whiskey, old fashioneds. Crushed ice is essential for tiki drinks, mint juleps, and tiki cocktails but melts fastest. Have both types if serving varied cocktails. Avoid small fast-melting cubes from cheap trays.
Should I buy bagged ice or make my own?
For 20+ guests, buy bagged ice - home freezers make 2-5 lbs/day, bags give 7-20 lbs instantly. Bagged ice is also cleaner (filtered water, commercial freezers). Make your own for dinner parties (clear ice looks elegant) or when you need specific sizes. Plan 3-5 days ahead if making all ice yourself.
How do I keep ice from melting too fast?
Store ice in cooler with tight lid, wrapped in towels (insulation). Keep coolers in shade, never direct sun. Use block ice - melts slower than cubes. Pre-chill cooler before adding ice. Do not drain meltwater - cold water insulates remaining ice. Open cooler minimally. For serving, use ice buckets with tongs, not bare hands (body heat melts ice).
