The amount of hops depends on the diameter of the internal filter of the device, in general our company produces two types of HopsMaster, i.e. HM300 where the filter diameter is 100 and the filter length is 1000mm and HM500 where the filter diameter is 250mm and the filter height is 1000mm. The area of the filter is decisive for the maceration of the drink itself and determines how many kg of hop pellets can be used for one cycle of cold hopping. Generally, after dissolving the hop pellets in the HM body, a so-called filter bed is formed on the filter body, through which the drink passes and thus hop essences are extracted into the drink (beer). The user should therefore always choose such a quantity of hops that the pump is able to push the drink through the filtering surface of the filter (formed by the dissolved pellets) and some optimal flow rate is maintained. A common amount of pellets for one cycle is between 28-56g of hops per 19L of beer. If you want to achieve just a hint of hop aroma, you can use only 14 g of hop pellets. If you want your beer to have a distinct bitterness and hop aroma, we recommend using around 112 grams of hop pellets.
