The Brown Derby Cocktail, LA's Vintage Cocktail (Dr. Cush's Exotic Cocktails)

 I love libations with a bit of history and flair to them. This is a simple drink, but the ingredients are top-notch and it helps that there's some reference to yesteryear. I'd def drink this on a rainy day here. 

1.5 oz. 100 Proof Bourbon 1 oz Grapefruit Juice .5 oz. Honey Syrup
