In Boston, Tim and Howard go back in time in search of the recipe for the lost colonial rum that started America's outlaw liquor legacy. With help from Tickle and a few other patriots, they recreate the spirit that was a favorite of Paul Revere.

Tim and Howard scour Pennsylvania for pre-prohibition rye and a colonial-era grist mill to recreate a spirit that sparked the Whiskey Rebellion in 1791. During their search, Tickle builds a unique still to help them distill this lost American rye whiskey.

Tim lures Tickle to Kentucky on a quest to unearth the origins of sour mash whiskey and why it changed American distilling forever. With help from Howard and Art, they build a period-correct pot still to recreate a recipe nearly two centuries-old.
