#1 OBSV Glass: Glencairn, rested 15 minutes. Color: Medium amber. Nose: Lots of bright fruit, some floral notes. Palate: Sweet clove coats the tongue, some baking spice. Finish: Long length with medium heat. Splash: No new flavors are revealed. Overall: 7.5/10 - This is a nice recipe, but lacks some of the classic bourbon notes (vanilla, cinnamon, etc.) A good place to start, #2 OBSK Glass: Glencairn, rested 15 minutes. Color: Medium amber. Nose: Caramel and vanilla, with some earthy notes. Palate: Cinnamon and baking spice coats the tongue, some sweet clove. Finish: Long length with medium heat. Splash: A dry oaky note appears, and complements the other flavors well.

Palate: Oak and baking spice. Finish: Short length with medium heat. Splash: No new flavors are revealed. Overall: 6.5/10 - The nose is fantastic, but it left me wanting more. #4 OBSQ Glass: Glencairn, rested 15 minutes. Color: Medium amber. Nose: Caramel with some light fruit and floral notes. Palate: Cinnamon, clove, baking spice. Finish: Medium length with low heat. Splash: A dry oaky note appears, and complements the other flavors well.

Nose: Butterscotch, caramel, vanilla. Palate: Baking spice and oak, followed by cinnamon and clove. Finish: Medium length with medium heat. Splash: No new flavors are revealed.

Nose: Sweet with fruit and floral notes. Palate: Baking spice and clove. Finish: Medium length with low heat. Splash: No new flavors are revealed. Overall: 7/10 - The baking spice and clove notes are nice, but this is somewhat one-note compared to the others. #7 OESK Glass: Glencairn, rested 15 minutes. Color: Medium amber. Nose: Vanilla, caramel, toffee. Palate: Baking spice, clove, cinnamon. Finish: Medium length with medium heat. Splash: Sweet clove notes become more prominent. Overall: 8/10 - This is hitting most of the classic bourbon notes. A longer or hotter finish would be nice. #8 OESO Glass: Glencairn, rested 15 minutes. Color: Medium amber. Nose: Banana bread with honey and nuts. Palate: Tons of sweet clove and baking spice. Finish: Medium length with medium heat. Splash: A mild minty note appears. Overall: 9.5/10 - This is wildly complex, and surprising at every turn. So far, my favorite of the set. #9 OESQ Glass: Glencairn, rested 15 minutes. Color: Medium amber. Nose: Caramel and vanilla with some butterscotch notes. Palate: Cinnamon, sweet clove, baking spice. Finish: Long length with medium heat. Splash: No new flavors are revealed.

Nose: Butterscotch, toffee, caramel, vanilla. Palate: Clove, baking spice, oak tannins. Finish: Long length with medium heat. Splash: A mild minty note appears. Overall: 9/10 - Another with classic notes and a great finish. On par with OESQ. Average of all ten: 8.2 (not factoring in cost). If these were offered at a bar, I'd expect to pay more per shot. At $125 for the set, it's a fun experiment, but not all recipes are equally good. I'd buy the single barrels of the better ones, and leave the rest.
