Not once. I actually figured it was the most responsible alcohol choice because it was made with fermented grapes," the Charlie's Angels actress shared in a press release at the time. "But I had no idea of the process. One of the first conversations Katherine and I had about making a cleaner wine was ‘what are we going to add to it?’ We soon learned it wasn't what you added, it's what you didn't add.” “We learned most wine is not made with organic grapes and that it can be manipulated with over 70 additives. This completely changed the way we thought about it," Power added. "When we started asking for clean or organic wines in grocery stores, hotels and restaurants, all we got were eye-rolls." The brand later hit retailers like Whole Foods, Sprouts and Target. Close
