The first time I tried the HP10, I didn't love it. In hindsight, my disappointment sprang from the fact that it didn't quite seem like HP to me, lacking the dark fruit and lovely peat of the 12 and 18. Having just tried it for the second time, my opinion has changed.
The HP10 is different, but very good in its own right. Yes, it's lighter and more citrus in nature, but the interplay between the smoke and the fruit is classic HP. It's also somewhat complex. Most interestingly to me, the combination of fruitiness and oak give it a note that comes straight out of Speyside.
This may never be my favorite HP, but it's interesting, enjoyable, and a bargain to boot.
