Old Potrero Straight Malt Whiskey Finished in Port Barrels

Very limited-release expressions: a Straight Malt Whiskey Finished in Port Barrels. 100 percent rye mash aged in new American oak barrels and finished in port casks. No age statement. Bottled 57.3 percent alcohol by volume.

Appearance: A darker than average, reddish-brown amber almost like a red ale.
Nose: A whiff starts out of with a burst of caramel, but the aroma quickly broadens out into a fruit pastry-like bouquet, dominated by an earthier caramel and sweet cooked apples with notes of pear and spices. A few moments later, the aroma took a turn for the worse by developing into an unflattering combination of bitter baking chocolate, port, and a touch of licorice.
Palate: Taking a sip, the Port-finished single malt puts forward a tastier version of what I found distasteful in the nose – dominated by a richer but sweeter chocolate alongside a mellower port with spicy rye notes. As it sits on the tongue, it develops sweeter caramelly notes that are evened out by more pronounced touches of ginger and clove.
