Picked up a Longrow Red (11 yrs) which is finished in Cabernet hogsheads for the last 4 years.
It's unique and somewhat challenging. Very sweet, and the wine flavors show through prominently. Loads of peat, too. If you don't like finishes on your Scotch, you'll hate this - because the wine finish is very prominent. And it's different than Sherry or Port (or other fortified wines), this is just sweet red wine, grapes and tannins with a huge peat/smoke finish. Really rich and flavorful - but I could totally see how some folks would absolutely hate it. I don't!
