Some 150 years ago, bitters were booming, with some countless makers offering their concoctions to support the uniquely American cocktail culture. Then, prohibition brought it all to a screeching halt. As recently as 2004, there were only three brands of bitters available commercially. Today, there’s a resurrection happening in the craft cocktail movement, with an accompanying explosion of brands on the market. A Priori’s curated collection offers the busy buyer access to many top selling and up and coming bitters.
