Pure Hop Oil is the essential oil fraction derived from supercritical CO2 hop extract. Pure Hop Oil is virtually free of alpha acids and beta acids and will not provide any bitterness or contribute to a sun struck flavor. The key essential oil compounds found in Hop Oil are ß-pinene, myrcene, humulene, caryophyllene and linalool.
Pure Hop Oil is generally dosed post-fermentation to provide hoppy aroma/character, and can be used in conjunction with dry hopping, or in full replacement
Perception of hoppy character and various related notes in beer will depend on the quantity of product added and when the product is added.
Pure Hop Oil is generally dosed at levels 5 – 40ml per hectoliter, but normally not to exceed 10ml. Pure Hop Oil may be added without prior dilution to beer after fermentation preferably by metered injection into the beer stream during transfer. The dosing rate for a brewery would completely depend on brew house, beer style and intensity/flavor preferred. Pure Hop Oil dosage amounts can easily be tested in bottles of beer by dosing 5-20 µl of Pure Hop Oil in a 355ml room temperature bottle of beer and mix by inversion then chilled for two hours under refrigeration. Dilution of Pure Hop Oil at 1ml of oil into 100ml of ethanol and/or propylene glycol can produce a beer soluble matrix, but probably is unnecessary. Pure Hop Oil appears to have enough solubility in beer at these low dosage rates to produce the hoppy character required.
Standard packaging is available in 1 kg and 5 kg aluminum bottles.
Pure Hop Oil should be stored at a temperature between 32ºF and 42ºF (0ºC and 5ºC). Under these conditions, Pure Hop Oil will remain stable in closed containers for two (2) years.
