ISO Extract 30%
Typically used for post fermentation adjustment of beer bitterness.
OVERVIEW
Isomerized Hop Extract 30% (Iso-Extract) is produced from CO2 extract and contains only purified isomerized alpha acids
Iso-Extract can be used to top-up bitterness or used as a partial hop replacement
Iso-Extract is added post fermentation, greatly improving the utilization of iso-alpha acids into beer and therefore is the cheapest form of bittering
FLAVOR
Iso-Extract produces a clean, bitter flavor and, when used for adjustment, results in beers of consistent bitterness.
