The ONCE label is reserved for wines made in conjunction with some of the world's most respected Sommeliers. Eric Lilavois, COO of the Thomas Keller empire (French Laundry, Per Se, etc), is involved, as is Danny Meyer, known for Union Square Cafe. Mark Williamson of Willi’s Wine Bar and Maceo in Paris is an investor and Willi's was the first location to offer ONCE wines.

Larry Stone of Rubicon and Daniel Johnnes of restaurant Daniel in New York (and premiere Burgundy event in the US , Le Paulee) are involved in ONCE. Current ONCE wine selections include Pinot noirs made by Raj Parr of Michael Mina and Daniel Johnnes, and a Cabernet Franc made by Bernie Sun of Jean-Georges (Vongerichten) of New York . Paul Roberts, formerly of The French Laundry, was also involved.

 From the winery: "ONCE a year we sit down with the nation’s best sommeliers to discuss and blend their version of a perfect wine for their restaurant’s specific cuisine".
