Advanced Viticulture is proud of and thankful for the comments made by some of our clients:
"Mark is an important part of our team because he consistently produces results. His all around knowledge of climate, soil and viticulture has been invaluable to us. Especially at our most challenging sites."
Mike Benziger, Benziger Family Winery, Glen Ellen, CA
"We have been working with Advanced Viticulture for five years. We needed advice to bring our vineyard to a higher level of fruit quality and solve special plant/soil nutrient issues. We have found that Mark’s advice on vine nutrition, plant moisture management and trellising has enabled us to improve the fruit quality to the level we were seeking. [...] He is a strong proponent of using detailed scientific data on plants to confirm visual observation of plant nutrition issues which is a practice that we now regard highly."
Donald Hofer, Kiler Canyon Vineyards, Paso Robles, CA
"Advanced Viticulture has added value in making recommendations for operations that have resulted in improved vineyard health and increased production of high quality fruit.”
Bruce Conzelman, Conzelman Vineyards, Anderson Valley, CA
