Williams Seylem is an institution. The original cult pinot negociant in America. For pinotfiles this place is a mecca. Since then it has changed hands (and by that I mean about a decade ago). The juice is still superb, sourced from the best vineyards in the area, and service wonderful. Though you've got to be on the mailing list to visit. Appointment required: yes, and you need to be on the list, or find someone who is.
