Our Story
Founded by Master of Wine Geoffrey Moss, Lithica works exclusively with the wine industry. No agency dedicates their services to wine marketing as deeply as we do.

Many agencies provide compelling professional services. Our difference: we have unparalleled category knowledge, industry acumen, and passion. This is all we do, and it's what makes us such an effective long-term service provider.

Geoffrey Moss, MW
Geoffrey Moss earned his Master of Wine in Fall 2020, an achievement that tops his exploration of many facets of the wine industry. He was awarded the Villa Maria Award for his outstanding knowledge and understanding of viticulture and the Robert Mondavi Winery Award for the best performance across all the theory papers in the MW exam.

His resumé includes working with Don Triggs and family at Culmina Family Estate Winery and then as part of the team at the ambitious Phantom Creek Estates project, seeing the brand and winery emerge from start to completion.

Geoffrey founded Lithica Wine Marketing in 2019, a boutique agency that helps wineries develop effective, customer-centric business and marketing strategies. He runs the wine consulting business from Penticton in the heart of the Okanagan Valley.
