The Berkshires’ First Distillery Since Prohibition — and the Whiskey Distilled from Beer

November 1, 2016 · Updated July 24, 2026 · 9 min read

In the eighth grade, Chris Weld tried to build a still for a class science project. His mother found out, realized it was a federal offense, and shut it down. Forty years later, after a twenty-year career as a physician’s assistant in one of the busiest emergency rooms in the San Francisco Bay Area, Chris and his wife Tyler bought a neglected apple farm in Sheffield, Massachusetts. Beneath it they found one of the best granite-based springs in the world. That spring water is in every bottle of Berkshire Mountain Distillers spirits today — the Greylock Gin, the Ethereal Gins, the Ragged Mountain Rum, the Ice Glen Vodka, the Berkshire Bourbon, and the Two Lanterns American Whiskey distilled from Samuel Adams Boston Lager and aged four years in vintage bourbon barrels. The Berkshires’ first legal distillery since Prohibition, BMD is distributed in 19 states and has partnered multiple times with Jim Koch of Samuel Adams — two craft beverage pioneers who recognized each other across the aisle between beer and spirits and decided to build something neither could make alone.

Key Takeaways

The spring beneath the apple farm is the foundation of everything BMD makes — Chris Weld didn’t plan to build a distillery when he bought the neglected Sheffield farm. He planned to restore the apple orchard and make brandy. Then he discovered the granite-based spring beneath the property — exceptional water that became the literal foundation of every BMD spirit. Farm-to-glass starts with the water, and BMD’s water is genuinely exceptional.
Two Lanterns American Whiskey — distilled beer aged for four years — is one of the most creative collaborations in American craft spirits history — Berkshire Mountain Distillers distilled Samuel Adams Boston Lager — literally distilled the beer — aged it for four years in vintage bourbon barrels, and released Two Lanterns American Whiskey at $120 a bottle. The result carries notes of malt and piney Noble hop bitterness through the barrel character. Once emptied, the barrels went back to Sam Adams for a barrel-aged beer. A complete circle between two craft beverage pioneers.
The name Two Lanterns carries the full weight of American history — Two lanterns lit at Old North Church in Boston in 1775 signaled to the Sons of Liberty that the British were coming by sea — the alert that launched the American Revolution, triggered the ride of Paul Revere, and led to the Battles of Lexington and Concord. Samuel Adams was one of the patriots the British came to capture. Jim Koch named his beer after him. Chris Weld named the whiskey after the signal that saved him.
Chris Weld is a physician’s assistant who turned biochemistry into craft distilling — His background in biochemistry and emergency medicine gives him a scientific precision that most craft distillers don’t bring to the process. The Ethereal Gin series — where each release uses different botanicals grown in the distillery’s own greenhouses — is the clearest expression of that precision: controlled experimentation applied to flavor development in the same way a scientist iterates through variables.
BMD grows its own botanicals on site — a three-greenhouse farm within the distillery — Angelica root, lemon verbena, lemongrass, lavender, licorice, lavender, Blue Hubbard squash, and more are grown in the distillery’s greenhouses and outdoor beds, used both in the spirits and in cocktails at the tasting room. The farm-to-glass philosophy extends to the botanicals, not just the grain and water.

Chris Weld — From the ER to the Still House

Chris Weld grew up in Westchester County, New York with an early and specific interest in distillation. In the eighth grade he attempted to build a still for a class science project — the plan was shut down by his mother when she realized it was a federal offense. He channeled the same curiosity into biochemistry as an undergraduate, earned a master’s degree in emergency medicine, and spent the next twenty years as a physician’s assistant in one of the busiest emergency rooms in the San Francisco Bay Area.

He is, by his own description, someone who puts things together. The biochemistry gave him a scientific framework for understanding fermentation and distillation at a molecular level. The emergency room gave him calm under pressure, decisive judgment, and the ability to manage complex systems with multiple variables simultaneously. Both turned out to be essential when he left San Francisco, moved his family to Berkshire County in western Massachusetts, and started building the Berkshires’ first legal distillery since Prohibition.

“I had literally been at a friend’s house a few months ago and they had the vodka and gin at their house,” Massachusetts Governor Charlie Baker said on a visit to BMD. “I said ‘Jeez, I’ve never heard of those guys — I’ll have to make a note that if I’m out in the area to go pay them a visit.'” The Governor showed up and bottled spirits alongside the staff. That kind of genuine community engagement — local bartenders making drinks in the tasting room, regional events at the distillery, partnerships with neighboring farms and producers — is what Chris Weld means by “big picture viewpoint of the world with a little local tenderness.”

The Farm, the Spring, and the Greenhouse

Chris and Tyler Weld bought a neglected apple farm in Sheffield, Massachusetts with a couple of hundred apple trees. The original plan was to restore the orchard and make apple brandy. Then Chris discovered the granite-based spring beneath the property — water of exceptional purity and mineral character, filtered through the ancient granite bedrock of the Berkshires. That spring changed the plan. Apple brandy became a much larger vision: a full-spectrum craft distillery using regional grains, local botanicals, and that granite spring water in everything it produced.

The farm-to-glass philosophy at BMD extends well beyond the water. Three greenhouses on site grow the botanicals used in the gin program — angelica root, lemon verbena, lemongrass, lavender, licorice, Blue Hubbard squash, green peppers, sunflowers, and more. Grains for the whiskey and bourbon come from neighboring Berkshire County farms. The distillery uses regional materials wherever possible, creating a spirits portfolio that genuinely reflects the agricultural and geological character of the place it was built.

What Makes the Berkshire Spring Water Special

The granite bedrock beneath the Berkshires is among the most ancient in New England — volcanic rock formed over 400 million years ago, compressed and folded by the same geological forces that built the Appalachian Mountains. Water filtered slowly through this granite picks up minerals gradually while remaining exceptionally clean and neutral in pH — the ideal profile for distillery water. The same spring that supplies BMD’s production also reflects a broader regional water quality that has historically made western Massachusetts and the Pioneer Valley a zone of excellent agricultural production. Chris Weld’s spring is not a marketing claim. It is a geological asset.

The Spirits — Greylock, Ethereal, Berkshire Bourbon, and Beyond

The Berkshire Mountain Distillers Range
Greylock Gin — Named for the highest peak in Massachusetts and the flagship of the BMD range. Distilled with botanicals including juniper, coriander, angelica root, and a selection of the farm-grown herbs that give it a distinctly New England character. Gold Medal from the Beverage Tasting Institute. The gin that introduced BMD to the national craft spirits community.
Ethereal Gin Series — The most scientifically interesting spirits in the range. Each release uses a different combination of botanicals grown in the distillery’s own greenhouses, making every batch a genuinely distinct product rather than a consistent house style. The series is Chris Weld’s controlled experiment in botanical flavor development — the biochemist at work. Seasonal and limited; collected by serious gin enthusiasts.
Berkshire Bourbon — Small-batch bourbon using regional grains and granite spring water, earning Gold Medal Awards from both the Beverage Tasting Institute and the San Francisco Spirits Competition. National praise from GQ, Details, the New York Times, Wine Enthusiast, and Jim Murray’s Whisky Bible has established BMD’s bourbon as one of the most recognized craft bourbons in the Northeast.
Ragged Mountain Rum — Named for the ski area that shares the Berkshire landscape. Made with regional molasses and the granite spring water, producing a rum with more terroir connection than most American rums achieve.
Ice Glen Vodka and New England Corn Whiskey — Ice Glen is named for a famous Berkshire gorge where ice remains into summer; the corn whiskey reflects the region’s agricultural tradition. Both showcase what happens when craft spirits production takes its local sourcing seriously at every level.

Two Lanterns — The Collaboration That Bridges Beer and Whiskey

The collaboration between Berkshire Mountain Distillers and Samuel Adams began with a shared conviction: that the craft beer and craft spirits movements, which had developed largely in parallel, had more to say to each other than either industry had yet explored. Chris Weld and Jim Koch had both been pioneers — Koch brewing the first batch of Samuel Adams Boston Lager in his kitchen in 1984 and launching the American craft beer movement; Weld founding BMD in 2007 as one of the first wave of American craft distillers.

Two Lanterns American Whiskey is the most ambitious expression of what their partnership produced. BMD distilled Samuel Adams Boston Lager — the actual beer, fermented and then distilled rather than distilled from wort — and aged it for four years in vintage bourbon barrels. The resulting whiskey carries distinct notes of malt and piney Noble hop bitterness through the sweet fruity esters and barrel character of the four-year maturation. It is something that has never existed before: a whiskey that genuinely tastes like the beer it was distilled from, transformed but not erased by the barrel.

The Two Lanterns Story — Name, History, and the Complete Circle
The name: Two lanterns were lit at the steeple of Old North Church in Boston on the night of April 18, 1775 — the signal to the Sons of Liberty that the British were coming by sea to Lexington and Concord to capture Samuel Adams and John Hancock. The alert launched the American Revolution. Paul Revere began his ride. The battles of Lexington and Concord followed the next morning.
The beer: Jim Koch named Samuel Adams Boston Lager after the patriot the British came to capture in 1775. He brewed the first batch in his kitchen using his grandfather’s recipe in 1984, creating the beer that helped launch the American craft beer movement.
The whiskey: BMD distilled Samuel Adams Boston Lager and aged it four years in vintage bourbon barrels. Two Lanterns American Whiskey — named for the signal that saved the man the beer was named after — carries malt and Noble hop character through sweet fruity esters and barrel influence. SRP $120.
The complete circle: Once the bourbon barrels were fully emptied of Two Lanterns whiskey, they made the trip back to the Samuel Adams Boston Brewery to be used for a barrel-aged beer. The collaboration literally went full circle — beer became whiskey became barrel became beer again.

“After barrel aging for over four years, we can’t wait for drinkers to finally have the chance to enjoy Chris’ Two Lanterns whiskey distilled with Boston Lager,” Koch said at the release. “Chris is doing a lot of really cool things and it was fun and interesting for us to see how the ingredients and flavor in the beer influenced the final whiskey.”

Visiting Berkshire Mountain Distillers

Berkshire Mountain Distillers is located in Sheffield, Massachusetts — in the southern Berkshires, about two and a half hours from New York City and three hours from Boston. The tasting room hosts local bartenders who create seasonal cocktails from the BMD range, and the distillery’s community events — tastings, pairings, and regional celebrations — reflect Chris Weld’s commitment to the local community that sustained the business through its early years.
