Claim:
1. A method for adding hops in beer manufacture, said method comprising: separating a sub-quantity of aqueous fluid from a quantity of at least one of water, wort or beer; adding hop extract in liquid or pasty form to the sub-quantity of aqueous fluid forming a mixture of aqueous fluid and hop extract; producing a macroemulsion of the hop extract by emulsifying the hop extract in the sub-quantity of aqueous fluid, wherein at least 75% of hop extract droplets in the macroemulsion have a particle size of less than 20 μm; increasing the pressure in the macroemulsion of the hop extract to a feed pressure higher than 100 bar; producing a microemulsion of the hop extract by feeding the pressurized macroemulsion through a gap or a valve or by feeding the pressurized macroemulsion against a baffle plate, wherein at least 75% of hop extract droplets in the microemulsion have a particle size of less than 5 μm; and inserting at least a portion of the microemulsion of the hop extract into the beer manufacturing process.
