130
liters
How to estimate it
Fermi’s official “Napkin math”
Czech beer comes in half-liter glasses. How many does the average person drink a week, counting kids and people who don't drink? Czechs love it, so maybe 4.
- Half-liters a week
- 4
- Weeks in a year
- × 52
- Liters per glass
- × 0.5
- 4 × 52 × 0.5
- ≈ 104 liters
A Czech beer is about a pint. How many does the average person drink a week, counting kids and people who don't drink? Czechs love it, so maybe 4.
- Pints a week
- 4
- Weeks in a year
- × 52
- Pints in a gallon
- ÷ 8
- 4 × 52 ÷ 8
- ≈ 26 gallons
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- All beer per resident, non-alcoholic included (Czech Statistical Office, 2024)
- 130.5 liters
- Rounded
- ≈ 130 liters
