Well, I tasted a swallow of it, and so far have survived to tell the tale.
When cold, that dark, weird smell is much reduced, and (I hope) may dissipate over time. The taste of the Sahti itself is surprisingly mild, and thankfully (finally) there's none of that over-sweetness I was used to in 2Red and the young BDBrown.
Somewhere between the smell and the taste I may actually "get" it, but it could be wishful thinking, too.
