Four Roses Distillery](https://www.fourrosesbourbon.com) is adding a chestnut wood-finished bourbon to its limited-release lineup, announcing Experimental Series No. 003: Chestnut as the third entry in a series that has already worked through Mizunara and honey-seasoned casks. The expression goes on sale November 20 at the distillery's two Kentucky visitor centers — Lawrenceburg and Cox's Creek — at an SRP of $55 per 375ml bottle, positioning it squarely as a high-consideration holiday purchase for bourbon collectors and on-premise gift-trade accounts.
The Liquid & Production Protocol
The base spirit is Four Roses' six-year-old OBSK recipe — one of ten distinct bourbon recipes the distillery produces by combining two mashbills with five proprietary yeast strains. Mature OBSK was transferred into 250-liter barrels constructed from chestnut wood grown in Japan, with each barrel carrying a different toast and char specification. Finishing times ranged from five to eleven weeks; the distillery sampled each barrel individually and emptied it once it hit target flavor profile rather than pulling the entire lot at a fixed date. That barrel-by-barrel protocol is a meaningful production differentiator for a limited release, as it limits the window for over-extraction and preserves batch-to-batch consistency within a very small pool of cooperage.
Bottled at 104 proof (52% ABV), the finished expression opens with apricot and soft vanilla on the nose. The palate is described as rounded and creamy, with vanilla bean, pear, and ripe cherry notes alongside sweet toasted wood and baking spice; the finish extends with delicate fruit and brown sugar. Master Distiller Brent Elliott noted that chestnut's distinct character complemented OBSK's inherent spice and complexity without masking the underlying recipe — an important consideration for a brand whose identity is built on recipe transparency.
Route-to-Market Implications
The 375ml format and direct visitor-center rollout means this SKU bypasses the three-tier system entirely at launch, with no wholesaler involvement and no off-premise planogram placement announced. That DTC-at-distillery approach is common for ultra-limited Kentucky bourbon expressions and keeps depletion figures tightly controlled, though it caps volume potential to foot traffic and the distillery's own e-commerce or will-call capacity. For on-premise accounts and independent retailers hoping to stock the expression, availability will hinge on whether Four Roses elects to allocate remaining inventory through its distributor network after the initial release window — a move the brand has made with prior Experimental Series drops when supply permitted.
The holiday timing is deliberate. Limited-edition bourbon SKUs historically index well in the gift trade during Q4, and a 375ml format at $55 hits an accessible premium price point — well below the four-figure secondary market territory of Four Roses' annual Limited Edition Small Batch releases while still commanding meaningful shelf premiums over the core portfolio. For distributors and retailers tracking the super-premium bourbon segment, the Experimental Series functions as a proof-of-concept vehicle: low volume, high visibility, and a signal of where Four Roses' wood-finishing research may migrate into broader production runs.
Four Roses, established in 1888 and operating distilling and warehousing facilities in Lawrenceburg and Cox's Creek respectively, distributes its core portfolio globally. The brand has received top-tier recognition at major spirits competitions, including World's Best Single Barrel at the World Whiskies Awards. The Experimental Series sits at the apex of that portfolio, serving the collector and enthusiast channel that increasingly drives depletions in the spirits manufacturing and innovation space.
