What is your best mineral whisky?

I honestly have not really detected this before.

Would there be a particular distillery that produces whisky of such a character on a regular basis?

I certainly know what you mean with the ardbeg 10. My 2014 uigeadail also has this characteristic. It's also very noticeable in the Ileach cask strength, although I do find that a little young and rough, but I think that minerally, flinty character can go along with quite young peaty whiskies a bit.

@Sengjc The obvious answer to your question is, in my own opinion, Ardbeg. In fact, sometime I find that some of the Sherry finish are just a waste of this nice minerality. I assumed, maybe wrongly, that it comes from the water. And sometime, I think some salty notes are coming from the water as well. I find that Amrut has a salty malt even on unpeated bottle and I assume it comes from the water and the grain. Of course for the flinstone, it's minerality and smoke.

I had a Craighellachie once, all in finesse, with minerality like a white wine. But I do have to go back to Ardbeg 10 again, I think it was 2010 or 2011 batch, it was like a great Chablis, a Wonder!

I have to stop now. I am becoming romantic...

@Robert99

Thanks - I am have an opened bottle of Ardbeg Ten at the moment - I am not sure what the batch code is but I think it is 2014 since it comes as part of the 'Escape Pack'. I'll have a shot at it and lookout for this minerality.

For me it doesn't get much more mineral-y than Talisker. The stuff tastes like rocks and limestone to me.

@Hunggar I encountered Talisker at the beginning of my journey inthe world of Whisky. At the time I was not impressed by it. But I think it is time that I give it a second chance. If I found in it a nice minerality I will be more than please, if not... I will mesure how Small or great is the way I travaled during that journey. In bot case, it will be educating.
