HopShot is CO2-extracted hop resin that can be used for bittering or late additions to boiling wort — treat it just like leaf or pellet hops added during the boil. The HopShot syringe contains 5 milliliters of extract. One milliliter of HopShot yields approximately 10 IBUs in 5 gallons of 1.050 wort when boiled for 60 minutes. Test batches indicate that this bitterness may be slightly less agressive on the palate than your average hop addition. Click here for help with HopShot IBU calculations: HopShot
