Pasteur Brewing Louis Pasteur – Science, Health, and Brewing The proportions of this may vary. Loaf sugar is preferable to moist; some say a pound to a gallon, others a pound and a half. Some allow but half an ounce of ginger (sliced or bruised) to a gallon, others an ounce. A lemon to a gallon is the usual proportion, to which some add a quarter of an ounce or half an ounce of cream of tartar. The white of an egg to each gallon is useful for clarifying, but not absolutely necessary. Some people put a quarter of a pint of brandy to four gallons of beer by way of keeping it; half an ounce of hops boiled in it would answer the same purpose. Boil the sugar, and shaved rind of lemons; let it boil half an hour. Clear the lemons of the white pith and put them in the wine. When cool, stir in the yeast (two tablespoonfuls to a gallon), put it in the barrel without straining, and bung close. In a fortnight draw off and bottle. It will be ready for use in another fortnight, and will keep longer than ginger pop. If cream of tartar is used, pour the boiling liquor over it, but do not boil it.
