I took a tour of St Pete Cellars recently, and I’m pretty sure that Biodome engineers are less concerned with climate control than they are. I kid you not, I legitimately caught their Sommelier showing cute pictures of puppies to a 3-Liter of Chateau Petrus when he thought no one was watching. That being said, my experience with other serious wine professionals leads me to believe that this is standard protocol in all world-class wine cellars. Go see for yourself. Seriously.
