i've found the proportions to vary alot from mixologist to mixologist. Sometimes they're a lot boozier, sometimes not. I like them heavy on the bourbon. It's strange to say, but it's one of my favorite cocktails ever and I've been known to consume many, many of them in a sitting. Thanks for that lounge pass, indu. I drank those for 8 hours. Lucky for me I took a bump because they never would have let me on that flight!
