TL;DR - Quick Answer
The default 50-guest, 4-hour estimate reserves 250 total servings: 83 beers (4 cases), 17 wine bottles, and 5 liquor bottles. It assumes every guest drinks, uses the 33/33/34 Standard Crowd split, and leaves the optional buffer off.

Frequently Asked Questions
How many drinks do I need per person for a 4-hour wedding?
Sipulus budgets 2 servings per drinking guest in the first hour and 1 per later hour. For a 4-hour wedding, that is 5 servings per drinking guest before an optional buffer. Use the non-drinker control rather than treating every attendee as a drinker.
How many drinks per person per hour at a party?
The Sipulus planning model reserves 2 servings per drinking guest for the first hour, then 1 per later hour. The Standard Crowd profile splits the shopping list about evenly across beer, wine and cocktails; choose another profile if you know your guests prefer one category.
How much alcohol per person for 50 guests?
For 50 drinking guests at a 4-hour event, the Sipulus baseline is 250 servings. With the Standard Crowd profile, that rounds up to about 4 cases of beer, 17 bottles of wine, and 5 bottles of liquor. The calculator adjusts for non-drinkers, preferences and an optional buffer.
What about guests who don't drink alcohol?
Set the non-drinker control to the share you expect at your event. The calculator removes those guests before estimating alcohol inventory. Plan water, sodas, and appealing alcohol-free drinks separately.
Do guests drink more at evening events than daytime events?
This calculator does not assume that a daytime or evening crowd will behave a certain way. Enter the actual service duration, expected non-drinker share, and closest preference profile, then adjust the result to your event plan.
How many drinks per person for a corporate event vs. a wedding?
The tool uses the same inventory baseline for every event: 2 servings per drinking guest in the first hour and 1 per later hour. It does not infer behavior from an event label; duration, non-drinkers, crowd profile, and the optional buffer control the estimate.
