Combine about 2-4 cups of the water with the salt and sugar (if using) in a large pot and bring to a simmer, stirring until dissolved
Remove from heat, add Garvin's Infused Garlic Vinegar, and other optional flavorings. Add the remaining cold water to cool the brine completely. The brine must be cold before adding chicken.
Submerge the chicken in the cooled brine in a container or bag, ensuring it's fully covered. You can add ice blocks (4 cups)
Refrigerate. Brine chicken pieces for 1-4 hours and whole chickens for 4-8 hours or overnight.
After brining, rinse the chicken under cold water and pat dry. Cook as desired and discard the used brine
