I think it’s just Atlantic Brew Supply’s thing. Their event is only open to women and non-binary homebrewers or those that are interested in homebrewing but I see no reason it can’t spread to other areas and open it to any homebrewer interested in supporting the cause.
Otherwise, buy some Pink Boots hops and they’ll donate to the cause for you. I’ve bought the Veteran’s blend hops for a couple years now. The blend is a bit different each year and they donate to a different vet org each year.
