Your Wine Expert

One of the most wonderful aspects of our Celebration of Wine River Cruises is the opportunity to sail with an experienced wine expert. Their refined palates will allow your clients to swirl their glass and discover the unique notes of each varietal they sip, gain pairing recommendations and get answers to their questions about viticulture and more. Our Wine Hosts proudly bring bottles from either their winery or their favorite winery to conduct tastings and stimulate discussions on board. Most often sailing with members of their wine club, these hosts focus on highlighting the growing conditions and production techniques that create the unique characteristics of their wines as well as the differences between their bottles and those of the Old-World regions we sail through.

Kevin Bersofsky
Owner/Winemaker, Montagne Russe Wines, Healdsburg, CA

Kevin Bersofsky was born an East Coaster but now makes his home outside of San Francisco in Marin County. The closest his family ever got to wine was nice cold gallon jug of screw cap California Chablis on the second shelf of the family fridge. It wasn’t until Kevin went to Cornell University for Engineering that the world of wine would be discovered. In his senior year he was lucky enough to attend the wines class and a new universe opened up to him. Kevin would attend culinary school on the weekends when home from consulting assignments.

In 2005, Sutter Home gave Kevin a front row seat to winemaking, learning the ropes of the wine industry. The wine makers took him under their wing and taught him the basic skills to make wine. Starting around that time he invited 12 friends to make a barrel of Syrah with him in his garage. From that group grew Montagne Russe. The group continued to increase in size until 2013 when he and 130 people were making wine in his Napa garage. Unfortunately Kevin’s neighbor Ross didn’t share in his enthusiasm for wine and called Alcohol Tobacco and Firearms on him in October of 2013. After much legal wranglings Kevin found a loophole in the law, poured 4 barrels of wine down the drain and lived to continue on, starting Montagne Russe for real in 2015. His first pinots scored 94 and 95 pts from Robert Parker. So its no wonder his winery is called Montagne Russe (Roller Coaster in French).

Owner, Texas Hills Vineyard, Johnson City, TX

Prior to starting the journey into the world of grape growing and wine making, Kathy and her late husband Gary owned and operated a community pharmacy for over 20 years. In 1995, they relocated to Johnson City, Texas and bought land for the vineyard and winery. Always a lover of wine, Kathy's background in pharmacy involved studies in organic and biochemistry which made for a natural progression into being a part of the art and chemistry of wine making. As one of the first wineries in the Texas Hill Country, Texas Hills Vineyard matched the climate to the grape varietals by planting Pinot Grigio, Syrah and Sangiovee in the vineyard. Receiving recognition for their Pinot Grigio in 1997 and followed with many more accolades including winning a Gold medal for his Kick Butt Cab at an International Double Blind wine tasting competition. The Texas Hills Vineyard philosophy for making wine is: “Make wine that tastes good, not just follow what others are doing, follow your own sense of quality and good taste”.
