This was married as it went into the barrel, meaning the malt whiskies and grain whiskies spent the full maturation period (in sherry casks) together. 50/50 grain and malt, unchillfiltered and no coloring.
This is the best blended scotch whisky I've tasted to date (beating Chivas 25). It's a blend that definitely tastes like a blend, but in a great way -- the grain whiskies in here work well, increasing the overall flavor experience and adding complexity. Generally, this is mostly a big caramel number, with sherry notes fluttering about, and a lovely, oaky finish (I don't ever use the word "lovely" so that means a lot). Sweetish, with vanilla, and a mix of red and white fruits. I'm just blown away by how well the whole package works, it does what it does excellently. Yes, please!
Figgy sherry on the nose with some glue. Moderately sherried but then opens up into some bourbony corn flavors, coconut, and spicy wood notes. As Adam noted, the grain really adds some positive complexity and yields a unique experience. Nice work.
