# How Much Beer and Ice do I need for my Party?
The million-dollar question when organizing any event: How many liters of beer should I buy? Running short is a disaster, but overbuying is an unnecessary expense. This tool helps you calculate the exact amount of alcohol and, most importantly, how many bags of ice you need to keep it cold. Professional caterers and event planners use statistical consumption models - and now you can too, for free.# The Consumption Formula by Person
To estimate the alcohol needed, professional caterers use a formula based on the "Hourly Consumption Rate". It is not an exact science, but statistics show that at a standard party, approximately 1.5 units are consumed per hour per person. Factors like ambient temperature, food availability, and the social energy of the event all shift this baseline number. 1 drink/hour Chill Consumption

The Physics of Ice
Calculating ice is where most hosts fail. Ice serves two functions: Cooling (bringing beer from 25°C to 4°C) and Maintaining (fighting ambient heat). At temperatures above 30°C, the melt rate doubles. A full bag of ice in direct sun can be gone in under 20 minutes, leaving your beverages warm before the party peaks.
Professional Tip to Save Ice
Keep kegs and cans in the shade before adding ice. If drinks are warm in the sun, the first 50% of your ice bag will die within 10 minutes simply exchanging latent heat. Start with pre-chilled beverages to dramatically reduce how much ice you actually need to buy.# Reference Data for Logistics
A standard 50L keg yields around 200 servings. A typical bag of ice weighs 2kg. Knowing these figures, you can plan the transport and storage needed for your event without last-minute surprises. Account for ice melt during transport - a 30-minute drive in summer can cost you one full bag before the party even starts.Who is this tool for?
