We are proud to say all of the vineyards we manage are sustainably farmed. As strong supporters of Fish Friendly Farming, we have recently been recognized as one of the few winegrape growers to have been certified for 20+ years. La Prenda Vineyards Management has also been certified by the California Land Stewardship Institute (CLSI) since 2020. We have also been certified by the Detox Project with Glyphosate Residue Free Certified Products. This certification verifies that food and supplement products do not contain the world’s most used herbicide.
