Decanting. — In decanting wine care must be taken not to shake or disturb the crust when moving it about or drawing the cork, particularly of port wine. Never de- cant wine without a wine strainer, with some clean fine cambric in it, to prevent the crust and bits of cork going into the decanter. In decanting port wine do not drain it too close, as there are generally two-thirds of a wine- glassful of thick dregs in each bottle which ought to be rejected. In white wine there is not much deposit, but it should nevertheless be poured off very slowly, the bottle being raised gradually. Detannation of Wines. — 1. — The Formulary recommends the following method for removing the tannin or astringent matter from sherry wine: Sherry, 7 pt.; white of egg, 1 fl.oz.; alcohol, 1 pt. Beat the white of egg to a froth and mix it with wine; heat to about 170° F., or until the albumen is coagulated. Then cool, add the alcohol and after standing a few hours filter clear through paper. 166
