New Maker's Mark?
According to a few of the forums I frequent, and with confirmation from the master distiller himself on the comments section of this post, there's going to be a new expression of Maker's Mark coming out soon.
It looks like they're adding toasted oak staves the barrel, and increasing the bottled proof. Pretty cool, considering the variations of MM have been really limited (I like the mint julep version, since I can't make an actual mint julep to save my life). Not sure when the ETA is for stores, but I'll definitely check it out.
