NOTES:
Check for defective air vents. (see Flat Beer, Corrections #3
and 4.)
Always turn pressure on before drawing beer.
Rotate stock. The oldest beer should be tapped first; if beer
has been allowed to stand in warm temperature beyond 45°F
for any excessive length of time, it may begin secondary
fermentation.
Store beer at 40° all year round.
