Media Luna Vineyards Team


Nicole DeMeo and Jennifer Grayzar - Owners,  Wine Lovers turned Winemakers ~ Media Luna Vineyards
Nicole DeMeo is a relentless and serial entrepreneur, venture capital partner and technology business growth advisor during her day job. Growing up in the wine country, Nicole always dreamed of owning her own vineyard. By partnering with Jennifer Grayzar and purchasing Media Luna Vineyards from the Vines of Mendoza, Nicole was in a way able to steal back her childhood.

Jennifer is an Emergency Medicine physician who has a passion to help others. She finds great insight and peace during her long walks in the vineyard. Jennifer is an oenophile, and is always ready to discover new wines, even after a very long shift in the ER.

When it came time to name the vineyard it was clear. They had traveled extensively together for years doing cartwheels all over the world as a way to celebrate life. Since Media Luna means cartwheel in Spanish, the decision was obvious.

Cartwheels represent exuberance and finding joy in the little moments – something that reflects how they live their lives fully and create wines to help you enjoy yours!

"Media Luna Vineyards always brings me good memories. The vines in lot#12 have always managed to successfully tackle every critical stage in their development.

Media Luna and The Vines of Mendoza Project

In December 2004, Michael Evans (CEO) and creator of the featured book, Nada es Imposible (Nothing is Impossible) went to Mendoza for a long weekend of wine tasting and he never left. The magic and majesty of Mendoza, along with the chance meeting of co-founder Pablo Gimenez Riili, resulted in the creation of The Vines of Mendoza in the Spring of 2005.

Media Luna was one of the earliest vineyards purchased in 2007 and planted in 2008 as part of this incredible project that includes private vineyard estates, wineries, a world-class, five star rated resort and Francis Mallman’s Siete Fuegos restaurant. We invite you to join us at The Vines of Mendoza and Media Luna Vineyards in Mendoza Argentina.
