It is indeed a sherry (fortified wine) and it’s made in many rural places in Durpar (and pre-Spellplague, all over Var the Golden, whose producers at that time boasted they made “the best Sharaerann”). Domestic Sharaerann is made and drunk right away, but most exported Sharaerann is the stronger, aged for three years or more “Sharaerann Amber,” and comes to the wider world from businesses in the port city of Vaelan who blend the sherry they buy from various farm producers in big casks, for aging, then tap the casks into smaller barrels for shipping, notably to Amn, Tethyr, and (largely for transshipment by caravan all over Faerûn) the ports of Baldur’s Gate and Waterdeep.
