Underground storage in a thick-walled (vibration-free) brick building by the Hudson River keeps relative humidity at around 70 % and temperatures are controlled at 55 deg F. Charges are based on either open storage, private 18-, 36- or 72-case lockers, and custom-built lockers holding between 100 and 1,000 cases. Open, inventoried storage costs $5 a case (for up to 99 cases) a month, which includes insurance, while private lockers come in at $70, $130 and $225 a month respectively, so it ain't cheap. On the other hand, CWS say they have 'tasting areas and staging tables so our clients can enjoy the experience as a hobby or connoisseur. There's plenty of room to enjoy working on their collection or sharing a glass with another client or my staff. Most of my staff is formally educated in wine fundamentals' – all of which makes it sound like one big party. There's also a sophisticated online system, including maturity advice.
