Groth Vineyards & Winery believes that a significant portion of the magic in the bottle comes from what goes on out in the vineyards. Since 1996 Groth has replanted 90% of our vineyards. This major undertaking allows to take advantage of the strides that have been reached in the viticulture community over the last decade, and combine them with the history with the land, to give us the ultimate combination between the grapes and the wine that we eventually make from them.
