in open headed casks or vats : in this situation, it is likely to undergo a proper fermentation, and the person attending may with great correctness ascertain when the first fermentation ceases ; this is of great importance, and must be particularly attended to. The fermentation is attended with a hissing noise, bubbles rising to the surface and there torming a soft spongy crust over the liquor. When this crust begins to crack, and a white froth appears in the cracks level with the surface of the head, the fermentation is about stopping. At this time the liquor is in the fine genuine clear state, and must be drawn oft immediately into clean casks ; and this is the time to fumigate it with sulphur. To do this, take a strip of canvas or rag, about two inches broad and twelve inches long, dip this into melted sulphur, and when a few pails of worked cider are put into the cask, set this match on fire and hold it in the cask till it is consumed, then bung the cask and shake it that the liquor may incorporate with, and retain the fumes ; after this, fill the cask and bung it up This cider should be racked off again the latter part of February, or first of March ; and if not as clear as you wish it, put in isinglass, to fine ; and stir it well ; then put the cask in a cool place where it will not be disturbed, for the finery to settle. Cider, prepared in this manner will keep sweet for years.
Mr. Deane observes "I have found it answer well to do nothing to cider till March, or the beginning of April, except giving a cask a small vent hole, and keeping it open till the first fermentation is over ; then draw it off into good casks ; and then fine it with skim milk, eggs broke up with the shells, or molasses. A quart of molasses will give a fine flavour to a barrel of cider, as well as carry all the lees to the bottom. But lest it should incline the liquor to prick I put in at the same time a quart of rum or brandy; and it seldom fails of keeping well to the end of summer. Cellars in which cider is kept should have neither doors nor windows
