Single cask, ex-bourbon matured, bottled for the state of Oklahoma, nearly 60% ABV. I haven't previously tried any Penderyn. The nose is green apple, cotton candy, banana, pear tart, creamy custard. On the palate, the proof hits hard. I hardly ever find whiskies to be too hot, but this one is. A little water to tame the Welsh dragon. Now pear juice, ginger, honey, banana, tropical fruit, coffee. The finish goes fairly bitter. There are some appealing flavors in here, but it's probably too young and the balance is off. Without water it's much too hot, and with water it finishes with too much bitterness. This was a Christmas gift, so I have no complaints for the price to me, but if I'm spending my own money I'm not a buyer at what appears to be over $100 locally, and this isn't piquing my interest in spending on their other offerings.
