I visited Save the World brewing last month and had their Biere de Garde and it was excellent. I know may years ago New Belgium offered it. I don't see that style on the shelves here in Texas often or at all. Maybe I'm not looking hard enough, but what brewery offers that off the shelf in Texas?
Although you might not be able to find it on the shelves, Jester King's Repose is "labeled" a BdG, though it appears as if it doesn't really fit the description well. https://www.beeradvocate.com/beer/style/127/ https://www.beeradvocate.com/beer/profile/24018/159551/
