Rapidase pectic enzyme details

From Presque Isle:

Rapidase Vino Super, liquid pectic enzyme, 1 oz dropper bottle (30 mL). It improves juice yield and provides faster and more compact settling of juices as well as improved filterability. It is active over a range of 45°F to 131°F with a doubling of activity for each 10° F rise in temperature. It will lose 3 to 5% of its strength per year when stored in a refrigerator, but more than 20% at ambient temperatures. Normal usage is 12 to 24 mL per ton (1.5 to 3 drops per gallon). 1 mL = about 20 drops. Double the rate for Vitis labrusca grapes and triple the rate for most other fruits. Use even more with peaches and plums. It is designed primarily for white wines because color extraction is not as good as the macerating enzymes such as Ex-Color, Adex-G or Crystalzyme Tinto, but it is still used with reds where free run yields and settling are important.
