Old Potrero Straight Malt Whiskey Finished in Port Barrels

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.
