Oloroso Sherry, from Jerez and Montilla-Moriles, in Andalusia, Spain, is fermented from Palomino grapes and casked in a traditional, years-long oxidative aging process that yields a rich, nutty aroma and the dark spicy notes of Madera Noble (Noble Wood). Conviction Straight Bourbon Whiskey has been aged in one of these casks, infusing the bourbon with the warm, complex characteristics that make Oloroso casks among the most sought-after on Earth.
