Draft Beer Keg Formula:
| From: | To: |
The Draft Beer Keg Calculator estimates the number of servings from a keg based on its volume and serving size. It helps bartenders, event planners, and brewery professionals efficiently manage their draft beer inventory and serving quantities.
The calculator uses the simple yield formula:
Where:
Explanation: The equation calculates how many standard servings can be obtained from a keg by dividing the total volume by the serving size.
Details: Accurate yield calculation is essential for inventory management, cost control, and ensuring adequate supply for events and establishments serving draft beer.
Tips: Enter the total keg volume in liters and the serving size in liters. All values must be valid (volume > 0, serving size > 0).
Q1: What are standard keg sizes?
A: Common keg sizes include 20L (5.3 gal), 30L (7.9 gal), and 50L (13.2 gal) for commercial use, though sizes may vary by region and brewery.
Q2: What is a typical serving size for draft beer?
A: Standard serving sizes are usually 0.3L (10 oz) for a half-pint, 0.5L (16 oz) for a pint, or 1L (33 oz) for a large serving, depending on establishment and region.
Q3: Does the calculator account for foam and waste?
A: No, this calculator provides a theoretical maximum yield. In practice, you should account for approximately 10-20% waste due to foam, spillage, and line cleaning.
Q4: Can I use this for different units of measurement?
A: The calculator is designed for liters. For other units like gallons or ounces, convert your measurements to liters first for accurate results.
Q5: How accurate is the yield calculation?
A: The calculation is mathematically precise based on the inputs, but real-world yields may vary due to factors like temperature, dispensing pressure, and glassware size variations.
