You bring up a good point. I can’t recall a single fund-raiser in the past decade that was held at a brewery or distillery. I believe the context here is that wine establishments are where intellectuals would meet and discuss matters....and distillery/brewery operations are where the non-intellectuals would gather.
If Warren made some cheap shot about cheese-sniffing "Chardonnay Liberals" being Buttigieg's base, then she deserved to be tied to the stake and roasted for it, now.
