Iso Alpha Extract, 32 oz

This extract contains pure iso-alpha acids, which can be added to beer at any stage (post fermentation is best) to add up to 50% of its bitterness. (Not recommended for bittering your beer entirely since there are secondary benefits from wort boiling with hops.) However, our Iso-Alpha extract is useful for correcting an under-bittered beer and also for training yourself to judge bitterness levels.The Iso-Alpha extract can be added at any stage of brewing, but best utilization will occur if added just prior to bottling or to the serving keg.
