I have been meaning to compare these 2 for a while. I bought the Confederation reserve upon release and the last time I had the Double Barrel was well over a year ago. I have many small sample bottles of the DB free when I got my usual bottles of the Barrel Select. The Confederation Reserve is prices $10 more than the DB at $70CAD.
Nose: Very big difference here. The Confederation has a soft balanced wood with some mild citrus, pickle juice, as well as a few darker fruits. The Double Barrel is sharper, spicier and bolder. A type of marinating sauce and a sweeter note has lemon tarts and butterscotch.
Palate: Confederation has mild spices and a big oak that is not overwhelming. I cant put my finger on what the sweetness is, some type of fruit. Also potato chips. Double Barrel has a similar vanilla that the Barrel Select has, them comes the rush of bourbony spices. A custard creaminess comes through as well.
Finish. The Double Barrel seems longer with spices. Confederation is medium long, milder with toasted oak.
After I made notes on the nose of the Double Barrel, I was sometimes offended by the sour notes in it. Perhaps having the Confederation after has something to do with it. Its not not a bad thing...sometimes it turns to lemon zest and sometimes oranges.
I barely remember the DB being like this but I trust my nose more that I did 2 years ago. Compared to the Barrel Select the DB seems very unique.
I am favouring the Confederation tonight. I was liking the wood notes. At times its freshly cut lumber, other times its wet campfire, then sometimes its a big soft oak that many older whiskies have dominant.
If you want to know about prices to tastes, yes I am willing to pay $10 more for the Confederation. It really showed me its complexity tonight.
