Holy Mountain Sin Nanna Anniversary Bourbon Barrel-Aged Imperial Stout

Few imperial stouts command attention quite like Holy Mountain Brewing’s Sin Nanna Anniversary release. That a monumental, bourbon barrel-aged expression from one of Seattle’s most celebrated and boundary-pushing craft breweries. Born from a culture of meticulous barrel program curation, this limited anniversary edition represents the pinnacle of Holy Mountain’s dark ale craft, drawing its name from the ancient Sumerian moon deity and delivering a beer that feels genuinely mythic in character and depth.

A Masterpiece of the Barrel Room

Sin Nanna is an Imperial Stout aged in bourbon barrels. That a process that imparts extraordinary complexity to an already formidable base beer. The extended contact with charred American oak allows the spirit’s character to fully integrate with the stout’s dense, roasted foundation, producing a seamless marriage of grain and wood. Anniversary editions from Holy Mountain are produced in deliberately small quantities, making each bottle a genuine collector’s piece rather than a casual find.

Tasting Notes

In the glass, Sin Nanna pours an opaque, obsidian black with a tan crown of fine foam. The nose opens with generous waves of dark chocolate, vanilla bean, and toasted coconut, underpinned by rich caramel and a whisper of dried dark fruit. On the palate, expect a full-bodied, almost viscous texture carrying flavours of:

• Bittersweet dark chocolate and espresso
• Bourbon-soaked oak and warm vanilla
• Molasses, fig, and dried cherry
• A long, warming finish with subtle roasted grain bitterness

Rarity and Collector Appeal

Holy Mountain releases anniversary variants on an extremely limited basis, with allocations reaching European markets in very small numbers. The combination of provenance, production method, and release exclusivity places Sin Nanna firmly in the upper tier of American craft stout collecting.

This exceptional bottle is available at Wines & Spirits SA, Switzerland’s trusted source for premium and rare craft beverages. Then priced at CHF 75 — a remarkable opportunity for discerning collectors seeking a world-class American barrel-aged stout.
