Keep your wine upright for about a week after bottling, this allows any residual CO2 to escape from the bottle. Then wine should be stored on its side, in cool and constant temperature. If you have to store your wine upright and it will last you more than 2 years, then you should use synthetic corks.
Rinse your wine bottles with hot water right after emptying them and dry them upside down. Store them in your boxes upside down until you come into come in to bottle again. It’s a good idea to wash your bottles in a mild bleach solution after every few uses. Beware of using a dishwasher to wash bottles, if you do it is best not to use detergent in the dishwasher as there will likely be residual detergent in the bottles.
Always make sure your bring your bottles in clean when you come to bottle your wine. You will sanitize them in our store right before bottling.
