{"product_id":"knob-creek-quarter-oak","title":"Knob Creek Quarter Oak 100 Proof Kentucky Straight Bourbon Whiskey 750 ml","description":"\u003cp\u003e\u003cstrong\u003eKnob Creek Quarter Oak is a bourbon finished in quarter casks — smaller barrels that increase the ratio of wood surface area to liquid, accelerating oak extraction and creating heavy oak notes that are then batched back with Knob Creek Straight Bourbon Whiskey to balance the intense oak with the traditional sweet notes of dried fruit and brown spice, producing a bourbon that is simultaneously bolder and more structured than the standard expression.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eQuarter casks are smaller than standard 53-gallon barrels — typically 13 gallons — meaning the whiskey contacts proportionally more wood per liter of liquid. This accelerated extraction produces heavier oak, more tannins, and more pronounced wood character in a shorter period than standard barrel aging. Knob Creek uses a minimum of four years in quarter casks before batching the wood-forward result back with standard Knob Creek Straight Bourbon to achieve balance — the heavy oak of the quarter cask component integrated with the vanilla sweetness and brown spice of the standard bourbon produces a more complex and structured whiskey than either component achieves alone.\u003c\/p\u003e\u003ch3\u003eTasting Notes\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e \u003cstrong\u003eNose:\u003c\/strong\u003e Heavy oak and charred wood from the quarter cask with the underlying caramel and brown sugar of the Knob Creek base\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePalate:\u003c\/strong\u003e Bold oak leading into dried fruit and brown spice, balanced by the sweet vanilla and caramel of the base bourbon\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFinish:\u003c\/strong\u003e Slightly sweet and charred oak with lingering dryness from the quarter cask tannins\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e \u003cstrong\u003eDistillery:\u003c\/strong\u003e Jim Beam, Clermont, Kentucky\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eStyle:\u003c\/strong\u003e Quarter Cask Finished Kentucky Straight Bourbon Whiskey\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFinish:\u003c\/strong\u003e Minimum 4 years in quarter casks, batched with straight bourbon\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eABV:\u003c\/strong\u003e 50% (100 Proof)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eSize:\u003c\/strong\u003e 750ml\u003c\/li\u003e \u003c\/ul\u003e\u003cp\u003eBrowse all \u003ca href=\"\/collections\/whiskey\"\u003ebourbon at Wooden Cork\u003c\/a\u003e.\u003c\/p\u003e\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"What do quarter casks do to bourbon?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Quarter casks are smaller than standard barrels — proportionally more wood contacts each liter of liquid, accelerating oak extraction and creating heavier oak, more tannins, and bolder wood character.
