Ultraviolet was started in 2009 by Samantha Sheehan of POE, when a friend of hers in St. Helena had a vineyard client drop out at the very last minute. He offered to sell the grapes at farming cost to Samantha, who could not pass up an opportunity for an exciting new project. Working with vineyards in Coombsville and St Helena, this winemaker is producing a Bordeaux style cabernet with all of the expression of the California terroir.
