Winemaking & Vineyards

Kimberlee Nicholls WINEMAKER at markham vineyards

Kimberlee Nicholls


“It’s so invigorating to be in Napa Valley or at this beautiful winery. When it smells like harvest, you can smell the grapes, it’s alive and it’s fantastic. It’s a fantastic job.”

Kim is a chemist full of energy and life, with a long history in Napa and a deep love of Merlot. As one of the first female winemakers in the Napa Valley, she is highly respected in the area. With three decades of experience under her belt, we are thrilled and humbled to have her on our team. Her food-friendly winemaking style is fueled by a love of cooking and the connective ritual of pairing lovingly prepared food with artfully made wines. Kim is an integral part of Markham’s story and has greatly contributed to our countless accolades and enduring place as one of Napa Valley’s great wineries.

Winemaker Abi Horstman

Abigail Horstman

Assistant Winemaker

An avid traveler, Abigail has worked harvests from Napa to Italy to Israel. She first joined the Markham cellar in 2017 as an enologist, and returned to the winery in 2021 to become our Assistant Winemaker. Her favorite thing about winemaking at Markham is the innovation and willingness to try new things and, of course, how food-friendly the wines are.

Patricia Sciacca ENOLOGIST at Markham Vineyards

Patricia Sciacca


A Napa Valley native, Patricia grew up on Atlas Peak high in the Vaca Mountain range that forms Napa Valley’s eastern edge. She earned her degree from Cal Poly SLO, where she developed a fascination with the effects of chemistry on the sensory aspects of wine. When not immersed in the cellar or lab, she enjoys spending time outdoors, hiking or fishing with her husband … or relaxing with a glass of wine alongside her tiny grey kitten Murphy and not-so-tiny rottweiler Magnum.

Taylor Abudi

Taylor Abudi

Viticulturist & Sustainability Manager

Taylor discovered her passion for science at an early age, and pursued a degree in viticulture & enology at UC Davis – which combined her love of science and the outdoors. After graduating, Taylor worked the vineyards of New Zealand, France, Australia and Oregon, where she learned that it always comes back to ensuring the land is well cared for. In her day-to-day, Taylor is focused on water conservation and building soil health through techniques like composting and the use of cover crops.
