Store Manager
Johns Creek

Jennifer grew up in Denton, Texas, before moving with her family to Georgia. She ventured out to college at the University of Nebraska in Kearney to study media, marketing, music, and design. Returning to Georgia, her career in alcohol sales started in 2007 in a retail shop in Suwanee where she promoted through the ranks to become the store manager. In these formative years, Jennifer studied wine under a renowned British sommelier. She also discovered a passion for bourbon during a trip through several distilleries on the Kentucky Bourbon Trail. Jennifer pursued her whiskey education and became a certified Stave & Thief bourbon steward in 2020. Before joining the Grapes & Grains team, Jennifer traveled throughout Georgia and South Carolina as a brand ambassador.  She truly enjoys introducing people to new and different whiskeys.

Kenneth Go

Wine Director

Born and raised in Queens, NY, Kenny took some left turns before happily landing in the wine industry. A graduate of the Air Force Academy & Florida State University business school, a military assignment in northern Italy introduced him to the mysteries of wine. A few restless stints in the military and government later, he found himself starting over as the manager of a wine & spirits shop in Knoxville. From there he spent over a half-decade at Green’s as their wine buyer, before joining the Grapes & Grains family as the wine director. A WSET IV Diploma holder & fan of all the NY teams that don’t win, Kenny resides in Adair Park with his wife, four children, and two slightly overweight cats.
