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.
Citrus-fresh aromas, tart grapefruit. Behind it powdered sugar / cotton candy sweetness.
Batch 3 is also quite floral again. The grape note from the STR wine barrel is also there.
Batch 2 seemed a bit more spicy, although Batch 3 also has spicy flavors, so they are a tad less for me.
here the oak is full again. In the first few seconds there was also an umami note, but it quickly evaporated.
Again good peppery, but the taste is a little more sweet than in Batch 2.
When I exhale through my nose I now have notes of vanilla, which I didn't have in Batch 2 (?).
Also quite short. The peppery (oak) spice tingles on the palate for a while.
