The reviewed bottle, marked L10 152, has been open for over 2 years. It is 70% full. The flavours have changed relatively little over that time.
Nose: relatively strong intensity peat and smoke, medium and high pitched barley malt, muted honey, and some brine. Delicious.
Taste: excellent translation onto the palate; the flavours are pointed and attention-getting. Sweetness is in abundance, more so than in the nose. This bottle has gotten a bit sweeter with time open.
Finish: long and strong continuation of flavours from the palate. They stay the same over a good span of time.
Balance: if you like the "sweet peat/smoke and brine" style of malts, then you will probably like Ardbeg Ten. You don't get the wine finishes with this, but then again, most peat-lovers can do without wine finishes for their malts. Within the genre of strongly flavoured highly peated smokey malt whiskies, Ardbeg Ten is a solid performer and an excellent value for money.
Funny, I just reviewed Ardbeg 10 as well...I presume your bottle is the standard one that is currently available - and not the ancient relic pictured?
This L10 152 bottle of Ardbeg Ten is still a 92 point whisky, 6 1/2 years later. Delicious. I have been conserving this bottle and still have half the bottle remaining. My friend @Nock, who is something of an Ardbeg specialist, concurs that L 10 152 is an exceptional batch of Ardbeg Ten. If I had known how good this batch is, I would have purchased several additional bottles of it back in early 2011. I like most batches of Ardbeg Ten, but not to equal this one. .
