American Patent Yeast.
I may add the following recipe for American patent yeast:—Take half a pound of hops and two pailfuls of water; mix and boil them till the liquid is reduced one half; strain the decoction into a tub, and when luke-warm add half a peck of malt. In the meantime, put the strained-off hops again into two pailfuls of water, and boil as before till they are reduced one half; strain the liquid while hot into a tub. (The heat will not injuriously affect malt previously mixed with tepid water.) When the liquid has cooled down to about blood heat, strain off the malt and add to the liquor two quarts of patent yeast set apart from the previous making by the above process. Five gallons of good yeast may thus be made which will be ready for use the day after it is made. It takes about eight hours’ time to manufacture, but gives very little trouble to the baker.
