 Beach was very secretive with his drink recipe ingredients, with only a select few of his bartenders knowing them.Some drinks Beach would only make himself, and he frequently placed alcohol into generic bottles labeled with only letters or numbers, or premixed "secret" ingredients in a similar fashion so that employees only needed to "mix X, Y, & Z with lime juice" to make a certain drink.Bergeron was less secretive with his ingredients over time, releasing two drink guides that carried his recipes, one in 1947 and the other in 1972.
