It helps the understanding of what is to be done if you have never made beer before to remember that any kind of sweetened liquor with a little yeast added will ferment and become "pop" in three or four days. The difference in strength of beers is according to the difference of amount of sweetening in the liquor used, strong beer or ale being made with plenty of malt and other sweetening added and small beer made by adding more water to the same malt for a second drawing. Once the method is understood it is only a question of different flavoring to make spruce beer, ginger beer, or any other variety as they all go through the same process.
