DESCRIPTION: FLEX® is a special formulation derived from pure hops, and its use is designed solely to provide bitterness to beer. FLEX eliminates a significant amount of the inert materials that come with the vegetative portion of hops and hop pellets, and thereby reduces weight, handling, and residual hop material that needs to be removed from the wort during brewing. The significant benefits from FLEX include its low viscosity, which allows it to be measured and dosed easily in the brewkettle, and the reduction of hop solids from wort, greatly reducing the process loss associated with the absorption of wort by the hop vegetative material. FLEX is designed for dosage early in the brewkettle boil and because the product provides hop alpha acids—the same as those found in whole hops and hop pellets—the isomerization of these alpha acids into iso-alpha acids is still necessary by means of the boiling process in the brewkettle. Switching from whole hops or hop pellets to FLEX will improve the utilization of the alpha acids for beer bittering, and the brewer can take comfort in knowing that the transition can be made with little or no effect on hop aroma.
