Hopsteiner ISO-Extract is added after fermentation and is
either used as a partial hop replacement (up to 70% of the
bitterness) or as a final adjustment to bitterness.
ISO-Extract provides the same form of iso-alpha-acid bitterness
that is acquired from traditional hopping. Hopsteiner ISO-Extract
allows the brewer to make fine adjustments of desired bitterness
in his beer. Essentially all the hop oils and beta acids
have been removed from this highly purified hop extract.
ISO-Extract is an extremely stable form of hop extract.
Stored in sealed containers at room temperature, Hopsteiner
lso-Extract will remain stable for years. Recommended storage
temperatures are 351F(21C) minimum, 90F(300C) maximum. The
reduced size and ambient storability lowers costs associated
with handling, storage, and shipping as compared to baled
hops. Exposure to direct sunlight should be avoided.
ISO-Extract improves beer quality by reducing the levels
of tannins and polyphenols in the beer. These improvements
are evident even when only a proportion of traditional hops
are replaced by Hopsteiner IsoExtract. Use of Hopsteiner
ISO-Extract often leads to noticeable improvement in physical
aspects of beer quality such as haze stability and beer
