Mammoth Distilling Whiskey 750ML is a 100% corn whiskey bottled at 40% ABV (80 proof) and finished in Grand Cru Merlot wine barrels from northern Michigan. What distinguishes this expression is its dual-state journey — aged five years in Kentucky before a secondary maturation in once-used Merlot casks from Bonobo Winery in the Traverse City area, layering subtle red-fruit complexity onto a classic corn whiskey backbone.Quick Facts: ABV: 40% | Origin: Central Lake, Michigan | 5-Year Aged, Wine Barrel Finished | Distillery: Mammoth DistillingProduction & HeritageMammoth Distilling operates out of Central Lake, Michigan, a small community in the northwestern corner of the Lower Peninsula. The distillery has established itself as a serious player in Michigan's growing craft spirits scene, producing a range of whiskeys, ryes, and other spirits. This particular expression starts as a straight corn whiskey — with a mashbill of at least 80% corn — distilled and put to barrel in Kentucky for a full five years. Once mature, the whiskey is transported to Mammoth's Central Lake facility, where it undergoes a finishing period in once-used Grand Cru Merlot barrels sourced from Bonobo Winery, a respected Traverse City-area producer. This finishing step marries the sweet, grainy character of aged corn whiskey with the tannic structure and fruit influence of premium wine casks.Tasting NotesAroma: The nose opens with an elegant warmth of beeswax, followed by fresh shucked corn and a clear honey sweetness. There is a subtle undercurrent of red fruit — a likely contribution from the Merlot cask finish — that rounds out the bouquet.Taste: On the palate, the corn-forward character leads with a creamy, almost buttery sweetness. The mid-palate introduces soft tannins and a hint of dark berry from the wine barrel influence, giving the whiskey more texture and dimension than a typical unfinished corn expression. At its peak, gentle vanilla and toasted oak emerge.Finish: The finish is notably smooth and approachable at 80 proof, with lingering notes of warm honey and a faint, dry tannic grip from the Merlot wood. It fades cleanly without harsh heat, making it easy to return to the glass.How to Drink Mammoth WhiskeyThe wine barrel influence and moderate proof make this whiskey an easy sipper neat or over a single large ice cube, where the cold draws out the honeyed corn sweetness. It also performs well in cocktails: Old Fashioned — The natural sweetness of the corn base reduces the need for added sugar, letting the Merlot barrel complexity shine through. Whiskey Sour — Citrus juice pairs naturally with the honey and beeswax character, and the wine-cask tannins add backbone against the acidity. Manhattan — The red-fruit undertones from the Merlot finish complement sweet vermouth without competing, creating a cohesive, fruit-forward variation.

Mammoth Distilling is based in Central Lake, Michigan, in the northwestern part of the state's Lower Peninsula. The whiskey itself is distilled and aged for five years in Kentucky before being finished on-site in Michigan in wine barrels.What foods pair well with Mammoth Whiskey? Smoked pork pairs well with the honey-corn sweetness. Aged cheddar echoes the tannic, slightly fruity barrel character. Dark chocolate highlights the beeswax and vanilla notes. Grilled stone fruit like peaches bridges the wine-cask influence. Cornbread with butter is a natural match for the 100% corn mashbill.What sizes does Mammoth Whiskey come in?

Mammoth Whiskey positions in the mid-range craft whiskey tier, and the five years of aging combined with a secondary wine barrel finish represent genuine production investment that justifies its pricing relative to younger or simpler craft alternatives.Why Mammoth Whiskey?The defining feature of this expression is its finishing regimen in once-used Grand Cru Merlot barrels from Bonobo Winery — a step that adds genuine complexity rather than serving as a marketing gimmick. Five years of initial aging in Kentucky gives the corn whiskey a mature, well-rounded base that can absorb the wine influence without being overwhelmed by it. In a craft whiskey landscape crowded with young, under-aged releases, Mammoth's decision to source properly aged stock and then add a thoughtful finishing step demonstrates restraint and intentionality. For drinkers curious about the intersection of American whiskey and wine-cask finishing, this bottling delivers a clear, well-executed example of what the technique can achieve.
