1st class MGP is getting more and more expensive and hard to find. This is a 12 year old version blended from two different high rye mash bills. That information is right on the front label. The proof is 100. I like the transparency. Rich oak fragrances jump from the glass. I love sniffing this one. The taste is true to the nose but it's not particularly complex. Don't get me wrong this is a really good bourbon but it's basic good as opposed to 80 a bottle good. I have tried three Remus products over the last couple months and liked them all. I think the single barrel at barrel proof is slightly better and 15 bucks less. The base version is 94 proof and gives this one a run for the money. There are a lot of 40-50 bourbons that are readily available and equally good or better. I'm looking at you Rare Breed and Four Roses SiB
