What is a BTG program supposed to do?
A by-the-glass program has one primary job: create entry points that guide guests toward bottle engagement. It isn’t a product list. It’s not a safety net for guests who won’t commit to a bottle. It’s a discovery channel with a destination, a window towards a bottle on the table.
When a BTG program performs correctly, a guest who orders a $16 pour of something they’ve never tried before finishes the glass, curious about what else the list offers. The pour was good and the staff made a compelling suggestion. Now the guest is asking about the bottle. That is the BTG program doing exactly what it’s supposed to do.
If the BTG program is too wide, or when the most affordable selection consistently outsells everything else, the program is creating a stopping point rather than a pathway. Guests find a comfortable price and park there. Bottle sales flatten. The program is technically busy and operationally bleeding.
Patrick Wert identified this dynamic in the Uchi Austin wine list critique, where a wide BTG program with a low-priced Cabernet at the base created the conditions for exactly this kind of ceiling behavior. The same structural tension appeared in different form during the Callie San Diego critique. The mechanism differs but the outcome is the same.
Design the BTG program as a sales tool with a clear direction. Every selection should point somewhere.
