This chart indicates how many 16 oz. glasses you are wasting every week, if your beer system does not have a Core Components FOB (froth on beer) Detector.
Without a Core Components FOB Detector you waste perfectly saleable beer as froth whenever you change a keg. To find out how much you are losing follow this simple calculation:
Example: 12 kegs per week and 90’ of beer line = 17 wasted 16 oz. glasses
Example: 17 wasted glasses x $2.00 profit per glass = $34.00.
Example: $34.00 weekly profit loss x 52 weeks = $1,768.00
Can you really afford to pour $__________ down the drain each year?
