Nose: Oatmeal cinnamon cookies! A little candied orange peel accompanies a slight alcohol bite. Dark red plums, cherries, and even some sweet raspberries. Another interesting red fruit pops out - strawberries, but more like fresh ripe strawberries rather than the stewed fruits I'd expect. Nice vanilla and spice on the end, specifically clove and cardamom - another rarity. Somehow reminds me of vanilla cake batter as well.
Palate: Spice and oily sweetness! Cinnamon, clove, maple? Small amount of other spices as well - anise and nutmeg. Sweet fruit syrup and wildflower honey. Warm, buttery maltiness that keeps coming in waves, slightly changed each time. Tingling on the middle of the tongue. Is that even some milk chocolate?
Finish: Long and mouthwatering! This lasts and lasts. That initial spice oatmeal cookie note is prominent in the finish as well, continually coming back between waves of baked cinnamon peaches and vanilla oak.
Adding water dulls the spices quite a bit and brings out much more vanilla and honey scents along with more fresh orange zest. It feels much thicker and sweeter at first, though the spices are actually more obvious on the taste than before, contrary to what the nose suggests. Much more like sweet sugar cookies with a dusting of cinnamon and some light raisins. Still lasts and lasts though - wonderful.
Conclusion: Wow! Absolutely stunning... This is one of the best whiskies I've ever poured. The original Redbreast 12 is my go to answer for when anyone asks what my favorite whiskey is, but this cask strength has just taken that spot.
