Once upon a time, Boston was a major center for distilled spirits in this country. An upswell of small-batch distillers in the area over the past several years may yet make this come true once more. The latest to enter the fray is Boston Harbor Distillery (The Port on Boston Harbor, 12R Ericsson St., bostonharbordistillery.com). Just recently opened to the public, this facility located on the Dorchester waterfront features tours and tastings Thursday and Friday from 4–8 p.m., Saturdays from noon–8 p.m. and Sundays from noon–5 p.m. The flagship product, Putnam New England Whiskey, is a single-malt whiskey made from 100% malted barley. The distillery’s brands also feature unique, New England-centric flavors, as in Lawley’s New England Spirit, made from molasses and maple syrup and available in white and aged versions.
