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. Despite this, many original cocktail recipes were lost to time, either because the recipes themselves were altered to reflect changing tastes (or restaurant budgets), or simply because memories faded and people died. The disagreement between Beach and Bergeron over who created the Mai Tai was not an isolated incident, and who "invented" what drink and when was frequently obscured by establishments that served cocktails with the same name but in sometimes remarkably different manners.
