I select the wines for the core program once a year. I just finished doing so for the 2020 list.
I tasted over 330 wines in December and January and narrowed them down based on our guest preference, trends in the market and price point. Our core program consists of about 35 wines by the glass and an additional 70 by the bottle. The remaining 50-90 selections are selected by the local management teams.
This allows for local guest favorites, wines not available in all states, and wines that the local teams enjoy.
I find that this affords a sense of ownership in the list and keeps the teams engaged more so than a completely mandated list. In addition to the selections, the local teams determine pricing based on their market. I still approve their selections and pricing choices.
