Boston-based Latitude Beverage Co. is extending 90+ Cellars with the Discovery Series, a collection meant to highlight under-the-radar wine regions and lesser-known grapes. The series debuts with two white wines: Lot 236 Pecorino from Italy and Lot 240 Torrontés from Argentina (each $15 a 750-ml.). Both are available at retail nationwide.
