Yes, there's a professional version of fthe same idea (probably after
he dreamt up his approach) that uses Nitrogen. The only problem is that
every study shows a wine degrades once it's opened, pretty much however
it's treated afterwards. But otherwise, his idea (and Nitrogen) can
definitely a couple of days of life to almost any bottle.

As an aside, Andrea Immer has a fantastic wine buyers guide where she
tests the life of a wine after it's open. Amazingly, even without
complex treatment, wines last anything from a day to three weeks,
depending on the wine.
