the ringbolt 18s were surprisingly really good for a young wine. Not one you can keep beyond 5 years IMO. At $12 is amazing. Dunno the vintage but most likely 19s. If only you could find the vintage. No knowing the vintage is part of the reason I've never bought from BB before.
I ordered a couple of weeks ago and got 17s (along with wynns black 15. Jackpot!!)
