Batch 3 has a slightly sweeter flavor than the previous batch. On the other hand, Batch 2 could come across a bit spicier on the nose.
Overall, the two batches are very, very similar:
absolutely similar in terms of aroma, taste, aftertaste, only nuances shift here and there. Unfortunately, I don't know batch 1.
If you only want this Nc'Nean as a "drinking whisky", you can choose between batch 2 and 3 - in my opinion they are so similar that it makes no difference.
If you want to collect it, please ... there are enough (at least in German shops), Batch 4 is also currently being bottled; that makes about 20,000 bottles, so everyone should be able to get something. And the current price between 50 and 55 is 'humane' for the first release, even if that was split into several batches.

A balanced young malt, which is suitable as a pleasing soup, but reveals a very tense inner life on closer inspection. I like the fact that the 2/3 red wine barrel influence is very cleverly integrated, so that their influence is never overpowering, but instead a stimulating interplay of sour-sour-spicy moments and vanilla-sweet-creamy impressions is created, with the always very clear fruit alternates again and again between light windfalls and grapes. It's great how harmoniously these two sides combine to create a harmonious overall impression.
