Heat granulated sugar in a medium saucepan over medium heat, stirring occasionally until sugar melts into a thick amber-brown syrup (5-7 minutes). Avoid burning. Remove from heat, add butter, and whisk briskly as mixture bubbles. If clumping occurs, whisk off heat to combine, then return to heat. Cook 30 seconds without stirring once blended. Off heat, slowly whisk in half the cream, then the rest, incorporating fully. Add salt, vanilla, and bourbon; whisk until smooth. Cool to room temperature before use, about 2 hours.

In a large bowl, combine peaches, brown sugar, vanilla extract, and lemon juice; let sit 5 minutes. In a separate bowl, mix granulated sugar, instant tapioca, cinnamon, and salt.

Remove bottom crust from refrigerator. Pour peach filling evenly into crust. Weave dough strips over filling in a lattice pattern, pulling back strips as needed. Seal strips to bottom crust edges and crimp decoratively. Whisk egg yolk with 15 milliliters water for egg wash. Brush lattice lightly and sprinkle with coarse sugar.

Place pie on parchment-lined baking sheet. Bake at 204°C for 25 minutes, then reduce oven to 177°C and bake an additional 25-30 minutes until filling bubbles and crust is golden. Tent with foil if crust browns too quickly. Remove from oven and cool at room temperature for at least 4 hours before slicing. Serve with cooled bourbon caramel sauce.
