What Causes Flat Beer?
Compressed air or the improper mix of beer gas (25% CO2)
“Serving your beer with air is the equivalent to pouring a pint, setting it down, and then drinking it the next day.”
- Flat beer is wasteful because you are putting extra (poor quality) beer in every glass. A 5/8" head is the equivalent of 4% of a pint. No head = 4% beer loss. Decreased Yield = decreased profit.
- Air is one of beer's worst enemies; it begins to destroy the product immediately on contact.
- Air contains oxygen, which will shorten the life of beer drastically; it can carry other flavours into the beer.
- Air contributes to the growth of several organic contaminates, requiring more frequent line cleaning.
- If the CO2 content in draft beer goes down, the beer will taste off and look unappealing (flat).
- A 25% CO2 mix does not have enough CO2 for proper dispense of most non-nitrogenated (domestic) draught brands, causing beer to go flat.
