Heavy, woody, almost sherrycask like.
Something deeply synthetic/chemical arrives over time. Old socks, sweaty tshirts. Deeply unpleasant.
With water: green boiled potatoes. Artificial sweeteners. Disgusting.
The synthetic/chemical smell is back. Mouldy sweaty socks.
With water: the alcohol steps forward, but the horrible taste still lingers.
Luckily not the longest, sort of medium.
