Adirondack Brewery, which opened in 1999 as a brewpub, plans a five-year, $5 million expansion that will include a distillery, tasting room, events space and expanded brewing and bottling facilities.

The brewery purchased a four-acre lot and building next to its location on Canada Street for $1.2 million from the Off Track Betting Corp., according to brewery owner John Carr.

The expanded brewery, to be attached to the rear of the OTB building, will triple Adirondack’s current capacity to 35,000 barrels of beer annually, Carr said.

Parking will move to the former OTB lot, and the brewery will add outdoor patio seating for its restaurant. It already has an outdoor deck. A tasting room and the distillery will go into the former OTB building, said Adirondack spokeswoman Laura Stevens.

The High Peaks distillery, as it will be called, will produce whiskeys and rye under the Cloud Splitter brand, and is projected to produce 5,000 cases of spirits annually.

Adirondack’s products are distributed in the Capital Region by DeCrescente Distributing Co. of Mechanicville.

Adirondack currently has four full-time brewers and a restaurant staff of about 20 during the off-season. In the summer, the restaurant staff increases to 40 to 50 full-time workers.
