High value? I give, I'm not sure. Sebastiani ships by rail. The current warehouses ship all kinds of Napa Valley wine which is considered premium wine Were not talking thunderbird. For specific brands I dont know .As for what not to buy, first consided quality ,taste ,color. clarity. fragrance ,aroma and price not whether its traveled in a boxcar or not. When selecting a wine don't be afaid to swish the wine around the roof of your mouth and spit it out..
