Not quite - Bruichladdich, whilst good, isn't peaty.
> It's not worth paying £100 for a single bottle. It really isn't any better than a standard 10 or 12 year single malt. Once matured at 10 or 12 years, keeping it longer doesn't improve the taste or quality any more.
You've been criticised for saying this, but the truth is it depends who's drinking it.
Different people have quite different sensitivities to tastes and smells, and some people will savour (or hate) components and depths to something which another person won't even detect.
As someone with virtually no sense of smell, I can really appreciate a good peaty malt (and have much less interest in those with less forceful flavours), but I often won't notice the small variations between different expressions.
So, for me (and for many others), there's every chance a £200 bottle will be no better than a £60 one, but that doesn't mean it won't be much better to someone who can appreciate it properly.
That said, if going for a special present, it's almost certainly best to go a step up from the standard, £30-£40 expressions - you can get something that, if not actually better, is as good but also a bit
different.
I recently finished a wonderful bottle of this:

better than Ardbeg 10 year old, but it's delicious and not like anything else. I see it's a bit over budget now, though!
