I think there are a lot of ways you could change or improve on this recipe. My first gut reaction was to express and discard a lime peel over the drink which brought out the bright notes in the citrus more. you could also reduce the amount of lime to make the bourbon more pronounced or reduce the simple to make it into more of a sour. Good as is but could definitely be improved on.
After your recommendation I tried the same thing, after adding a squeeze of lemon juice, and it opened the flavors much more than before and made it significantly more palatable. Thank you for the recommendation!
It felt flat so I added a orange peel twist on top of the lemon peel twist that made it taste more 3 dimensional. For people who are looking for a cocktail that simulates a peach tea, I would 100% recommend as long as you use higher quality ingredients or add something like I did to round it off.
The creole bitters really punch through, in this cocktail (for me). I recommend 1 dash instead of 2 because of that or even split the difference with 1.5 dashes (if possible).
