If you are fortunate enough to have an old cellar with good thermal insulation for a constant temperature, you can store your wines without a care in the world. Old cellars are usually damp, and that is good for the wines, too. If you are not so lucky, you can build up a smaller collection with the help of electrical wine cabinets. Another alternative is to install an air-conditioning system in the cellar and fit cold storage doors or to install a cold storage room. Sometimes it just takes a minor structural modification. In other cases, it might make more sense to rent a small cellar somewhere. The bottles are normally stored in the horizontal position so that the corks do not dry out. When the cork is wet, it swells and forms an airtight seal in the bottleneck. According to a new school of thought, it is better to store the bottles at an angle. The argument is that this keeps the cork in contact with both the wine and the air bubble, which contracts and expands with fluctuations in temperature. This ensures that air and not wine seeps into or through the cork. In Terlano we store the bottles horizontally. You can see from the wines that have been laid down for 20-30 years that oxygen exchange takes place to a very slight degree as reflected in the reduced volume of wine when the bottles are re-corked after about fifteen years – and the complex aromas that develop with such maturity.
