I'm a newbie also and after trying the yellow label a couple times at bars I jumped right into the single barrel selections from Binny's and TPS. Right now I have OBSV, OESO (both opened), OBSK, & OESK. (Both unopened). Both the OBSV and OESO are terrific. What I find strange is that I have to dilute the OBSV (55%) but can drink the OESO (59%) straight with no problem. Either way, these are among the favorites in my collection.
Agreed on the 1Bs. Last summer I picked up an OESO 12 yr and an OBSK 17 yr, both at cask strength, from the distillery shop.
The OBSK 17 yr was one of the top 5 whiskies I've ever tasted. Got about one drink left in the bottle, and then the cryin' starts!
