Cameron and Katherine co-founded Avaline in July of 2020 with the aim of providing clean, organic and vegan wines. 

'My good friend Katherine Power and I were catching up over a glass— as the wine started to flow, so did our conversation about it,' the actress said. 'We kind of had that moment where we were like, 'God we love wine — what's in it?' 

'Can we really drink this? How can we drink more of it? We started asking questions about our wine; which is so crazy because I had never done that before,' she added when asked why she started the brand.

Katherine's response was: 'We're pushing for a way of living that is all things clean and organic. It never occurred to us that wine wouldn't fall under this category. 

'We were shocked to learn the ingredients that were added and the lack of transparency. The journey to learning more about the winemaking process and how to make clean, delicious wine led us to create Avaline,' she said.

The entrepreneurs were clear on their website that they wanted to prioritize the safe consumption of wine, noting that it starts with being transparent about ingredients.

'The wine industry has somehow gotten away with not having to be transparent or disclose what's in the bottle,' Katherine added.

'A lot of people might not care if animal by-products are used in the making of the wine, but we believe the consumer should be aware of that step so that they can make that decision for themselves,' she finished.
