Unhopped beers contain more fusel oils than the corresponding normally hopped beers when certain strains of yeasts are used during fermentation. Water soluble fractions of hops and some soft resin constituents can influence fusel oil production. When hops are completely replaced by isomerized hop extracts the use of some additional hop fraction in the copper leads to the resulting beer having a similar fusel oil content to one hopped in the usual way. Partially hopped beers (0·25 lb./brl.) usually have similar fusel oil contents to beers produced using the normal quantity of hops (1·0 lb./brl.).
