Whisky / Whiskey / Bourbon

I know next to nothing about whisky, I've got a couple of bottles on the go at the moment, one is a Balvenie Doublewood which is pretty nice, very sweet and very easy to drink. The other one is a 10 year old Talisker which is almost the exact opposite, very smokey and spicy, but very nice in a different way. I'm right at the end of the Talisker, are there any recommendations for similar whiskys? I want to try something new but I'd like something a bit more fiery than the Balvenie, to give me a bit more choice and variety.

There aren't too many others that I would say have the peppery, fiery quality of Talisker; it is what makes Talisker so unique. But for smokey I would seek out a Caol Ila 18 if you can.

Otherwise, as people have said, Ardbeg is good quality and value. Laphroaig 10 is pretty sharp, and I prefer the quarter cask, but really any Laphroaig is good to me. But it was an acquired taste.

Lagavulin would be the other Islay whisky that I think really fits that peaty, smokey profile. Very well rounded and lush.

I'm a big fan of Ardbeg 10, but it's a very unique one (salty and vigorous), as is Lagavulin (rich and complex... "the aristocrat of Islay"), as is Laphroaig (smelly and brutish). Three distilleries on one road but different flavours. All lovely by the way, but very specific. I wouldn't rush to recommend any of them of the brief is 'something a bit like Talisker'. What about Bowmore? For an Islay it's relatively soft and a good introduction.

I drank a lot of Bunnahabhain (sp?) over Christmas. It's the only unpeated Islay whisky and is really nice. Very easy going. Thoroughly recommended.

Actually I've got a little 20cl bottle of the Oban unopened so i might give that a go next, avoid spending money I don't have.

Probably ideal actually, a nice all-rounder with lots of fruit and spice IIRC.
