What's up with this Minervois?

I recently bought a bottle of the 2005 Chateau de Miremont La Grande Cuvee V.V. and found a couple of favorable reviews on CellarTracker but nothing on Wine-Searcher. Doing a google search, it seems that the chateau is in the business of hosting receptions/birthday parties etc. but no mention of wine production. Do they own vineyards or just buy in grapes? Am I confusing this chateau with another that does produce wine? This bottle was imported by Jandell Selections.

Lots of places in France with same name (like Springfield or Greenville in US). The Miremont wedding hall that you googled looks to be in Auvergne, far to north of Minervois.
But if you google Miremont Minervois there are several hits (in French) referring to a 20 ha estate.
