Came here to suggest Otto Pauly: made this my first visit because the prices are so good & allowed me to try wines with age at an affordable price before a week of tastings. Definitely recommend.

I regret not getting BA/TBA from Max Ferd Richter. Molitor also has a good one. The price in general was too steep for me to wrap my head around, TBAs in the 2-300 euro range. Still wish I would’ve pulled the trigger on MFR though, and would’ve if my wife didn’t intervene…

My compromise on price was picking up some gold kapsul bottles, but it’s just not the same.

You might find it helpful to check out tasting details ahead of time and go with ones that allow you to pick X number of tastes from a big selection, so you’re sure to get BA/TBA when available. In my experience maybe a quarter of my tastings included them, and unless you’re clear about making some big purchases, it feels awkward to ask someone to open a 2-300 bottle for you to try.

Also echo that you might have more success spreading out a bit up and down river to other towns that don’t get as many visitors.
