There is nothing quite like Christopher's in Houston. The creation of the husband-and-wife team of Christopher and Donna Massie, this 6,000-square-foot, single-venue operation offers rare wines that sometimes are allocated by growers and importers to less than one case for the entire state of Texas. French wines are showcased here, as Massie himself has lived and worked in French vineyards and is a certified sommelier with more than 15 years of experience. Other countries and, of course, California are also represented. The inventory usually runs to about 50,000 bottles, so there is likely to be something for every serious oenophile. And the inventory is properly stored, a detail that unfortunately not many Houston wine retailers attend to with the required rigor. On Saturdays, "Customer Appreciation Day," there are tastings and lectures on the products for sale.
