Are cocktails copyrighted?
US copyright law doesn't apply to lists of ingredients. These laws may apply to detailed instructions, particularly if they are novel or detailed. Think molecular mixology. "Stir, strain, straight up, cocktail glass, flamed orange peel." is fine. Sounds tasty. What were we talking about? Oh yeah.
Please don't submit cocktails from creators who don't wish them published. That's not nice.
Similarly, don't expect copyright protection on your cocktails. We believe that the vitality and creativity of the cocktail world is advanced by sharing recipes and attributing them to their creator. If you don't share this view, then you should keep your recipes secret.
