Had the opportunity to try this completely blind. I didn’t know if it was a blend or single malt, just an unmarked 2 oz bottle. I didn’t recognize it at all so I spent some time with it. I noted - leather and not much, if any, fruit and a healthy dose of peat. I poured a Laphroaig 10 beside to get a sense of the scale of smoke and it was maybe a third but definitely there and likely the dominant note. I listed round, rich and sweet in my palette notes. I listed finish as long (4 on a scale of 1 to 5). I liked it and I thought it was a lightly peated Islay at about 46 abv. Note that I didn’t pick up Caol Ila which is how I often identify Johnnie Walker Black or Green. Curious to know where Blue gets its peat from. Surprised that it was 40 abv, the richness of the dram means it doesn’t need to hide behind higher abv. Very good whisky.
