Cellar architect Jay Rosen's love of wine developed as a necessary provision during college. Later, in need of a storage space for his growing treasure trove of wines, Rosen, who then renovated houses for a living, would bring home a couple of two-by-fours every day and nail them into his basement walls. Plank by plank, he completed his 1,500-bottle cellar over a period of several months, also installing insulation and temperature controls. The construction of this makeshift cave compelled Rosen to start building wine-storage areas for clients, and he soon launched the cellar construction company he owns today, Washington Valley Cellars. Wine Spectator's Esther Mobley explains.
