From the perspective of someone who worked in some very popular wine-centric restaurants in New York and went from a pretty liberal corkage policy (no stated max number of bottles, $45 (I think), corkage waived with purchases), to a hard 2-bottle/table limit at a higher price ($65 by 2019, no waiving), the answer is simple, and disappointing:
We wanted to do wine service right, and I think most who did visit agree that we did, despite not being a fancy, big restaurant. Having a corkage policy that inspired people to come and also buy of the list was part of that. But as our reputation grew, the generous policy was abused by people (who should know better). “Wine VIPs” would show up with bags full of decades old bottles that needed chilling, decanting, rounds of glassware (Zaltos of course), linger forever etc. As nice as it is to be known for good wine service, if 6 guys show up unannounced with 2 bottles each that need top level service, every decanters and stem in the house - it does drag the whole restaurant down. It doesn’t really matter how nice the wine is or if they pour generous pours for the sommelier, the rest of the staff and tables is getting shafted.
My personal horror story was putting down 180 stems on a single ten-top, serving 18 bottles that were 20-50 years old, while I was the lone sommelier working a 200-guest evening. Sure, the wines were fantastic but I can’t remember a single one, I was so stressed and I wasn’t much use to the rest of the team, or 90% of the dining room. I was wrecked. Also, imagine being the glass polisher who’s there hours after service ends working a really thankless task (who by the way, cannot take part in tips)…
Another thing to consider: At another restaurant, in our first year of business we replaced Zaltos for over $20,000. Was a majority broken by BYOers? Probably not, but trust me when I say that a vast proportion of breakage happened during big wine dinners where guests have multiple glasses in front of them (and get hammered). We also had two full-time glass polishers - there’s a cost to that. And again, those polishers don’t count as front of house employees - not eligible for tips.
If I ever get into the restaurant business again, here’s how I’d formulate a corkage policy:
- Priced around the most inexpensive bottle on the list.
- Fee waived 1:1 for purchases off the list.
- Anything ABOVE 2 bottles/table must be communicated and approved ahead of time so extra staff can be brought in, glassware purchased/rented etc, and is most likely converted into a “sommelier & glassware” fee instead of a per bottle fee so your table can get the actual service needed and the rest of the dining room doesn’t suffer.
- Anything above 2 bottles should be delivered prior, ideally day before if it’s old wine that needs to settle, get to the correct temperature etc without unnecessary stress.
- The “can’t BYO something on the list” rule is a nice idea, but is basically unenforceable in reality. But maybe it’ll force some people to actually look at the list.
Also, I saw another thread recently where someone was upset about not being comped the corkage fee because he poured the sommelier a glass. 1. In most cases, sommeliers can’t make that call. 2. Most wine brought in as corkage is terrible, and it comes at a time cost. The number of times I’ve had to stand at a table pretending to be interested in hearing about someone’s wine collection while trying not to barf swallowing down a “generous pour” of The Prisoner. yeah…
