For the brine, in a small pot, heat water, vinegar, salt and sugar to dissolve and combine. When it comes to a low boil, remove from heat and add a few cups of ice to melt. Add the mixture to double-lined bags balanced in a large bowl, add a quart of buttermilk, herbs, bay leaves and garlic. Add chicken to the brine, remove excess air, seal, and refrigerate the chicken 12 to 24 hours.
Remove the chicken pieces, draining off excess brine, to a rack-lined rimmed baking sheet. Discard brine.
Set up another rack-lined tray.
Dredge chicken and double coat in flour, then batter, then flour again and arrange on tray. Let stand or refrigerate for 1 hour for chicken to adhere and expand the crust mixture.
Heat oil to 350˚F and fry chicken in small batches, about 12 minutes until 160˚F on an instant-read thermometer. Drain on clean rack-lined sheet pan.
Serve chicken with hot sauce, hot honey, slaw or salad of choice, and warm biscuits to pass.
