AFAIK the 12yr CS was not available for public tasting in Leiden. There was only one bottle which got popped open and I was asured I was the first to have this new dram on the mainland.
It was the first malt I was tasting at the event, so my palate wasnt really open yet. But it indeed needs a bit of water to open up. At 57.2% and a whole festival in front a wise thing anyway
My initial note had smoke and earthy tones without water, and with water more fruit and sweeter tones. But I really should give this expression more time later for a proper note. Wasnt bad at all though
