RB15 an ode to the 12, bourbon and oloroso sherry makes a much anticipated return for a rich and intense experience. The aromatics—very bright and acidic, notes of citrus and a woody influence poke through. The maturity of the casks definitely provide a more in depth aromatics. The taste—scotch, scotch, scotch, very interesting flavor profile, floral earthy tones, feel peated, but “unintimidating” this mellow/rich experience is smoky, woody, and spicy work in tandem for an mellow cascade of balanced matured sweetness with a long lingering spice. Definitely enjoyed this pour, although, the 12 remains the favorite, this should not be slept on—this would make a very enjoyable single malt and comparatively it could hold its on in terms of upfront notes of smokiness and juicy spice, which provide a memorable tasteful experience.
