Alambique Serrano Altos Esteres High Ester Pot Still Rum 2nd Edition

Given its funky, high-ester profile and robust 63.9% ABV, Alambique Serrano Altos Esteres shines when used as a modifier in tiki drinks or tropical cocktails where its grassy, concentrated cane flavors add complexity, though adventurous drinkers can sip it neat with a splash of water to unlock its full aromatic range. This rum pairs beautifully with grilled meats, mole dishes, and aged cheeses, making it a year-round spirit that's especially satisfying on warm evenings when bold, funky flavors are most appreciated.

Nose: Intense aromas of overripe pineapple and fermented tropical fruit hit immediately, followed by funky notes of olive brine and green banana peel. There's a pronounced acetone sharpness typical of high-ester rums, along with hints of sour yogurt, fresh-cut grass, and white pepper. As it opens up, you'll find lighter notes of honeydew melon and a subtle mineral quality that speaks to the high-altitude terroir.

Palate: Bold and aggressive at full proof, delivering waves of concentrated pineapple juice, unripe mango, and tangy lime zest. The high ester character comes through with funky, almost savory notes—think green olives and sea salt. There's a grassy, vegetal quality from the fresh cane juice, along with white chocolate, cracked black pepper, and a slight bitter edge like grapefruit pith. The texture is oily and coating despite the lack of added sugar.

Finish: Long and warming with lingering tropical fruit esters that turn gradually more medicinal. The funk persists with notes of banana bread, bitter citrus peel, and a drying quality that leaves your mouth feeling clean. A peppery heat builds slowly, accompanied by hints of fresh sugarcane and that distinctive mineral character. The high proof leaves a pleasant warmth that spreads across the chest.

Alambique Serrano Altos Esteres undergoes an extended 25-day fermentation in pine tanks with ambient yeast, which develops concentrated ester compounds that give this rum its bold, funky character—think overripe tropical fruit meets nail polish remover in the best possible way. The Krassel family distills this juice from organic Java sugarcane grown at elevations up to 4,000 feet in copper pot stills, then bottles it at cask strength without dilution, preserving every bit of that wild, expressive personality.

• This rum undergoes a marathon 25-day fermentation in pine wood tanks, which is roughly five times longer than most rums—creating wild, funky esters that give it an almost wine-like complexity. Those pine tanks aren't just containers; they're actively shaping the flavor profile in ways stainless steel never could.
• The Krassel family grows their organic Java sugarcane at elevations up to 4,000 feet above sea level on steep Oaxacan hillsides, making this one of the highest-altitude rums in the world. The thinner air, cooler temperatures, and intense sunlight at that altitude produce sugarcane with distinctly different sugar compositions and aromatics than coastal varieties.
• Bottled at a eye-watering 63.9% ABV straight from the still with zero dilution or added sugar, this rum is basically the distiller saying "this is exactly what we made, take it or leave it." That cask strength preserves every ounce of those hard-earned high esters and terroir-driven flavors that would get muted in a standard 40% bottling.
