Conn. Gen. Stat. § 21a-142: (Formerly Sec. 19-276). Cleansing of containers.

Unclean bottles shall be exposed to a three and one-half per cent alkali solution of which not less than sixty per cent is caustic (sodium hydroxide), for a period of not less than five minutes at a temperature of not less than one hundred and twenty degrees Fahrenheit or to an equivalent cleansing and sterilizing process. The bottles shall be rinsed free of all caustic in potable water. No bottle shall be used on which the rubber part of the stopper may come into contact with the beverage. No person shall use as containers for beverages the “Hutchinson plunger” bottles or reuse any cap, crown or stopper. Caps, crowns or stoppers, before use, shall be kept in a device having a self-closing cover, and such caps, crowns or stoppers shall be placed on the bottles with an automatic capping device. All containers in which syrups, fruit juices, syrup fruit juices or flavors or other extracts are stored or prepared shall be constructed of porcelain, glass, glaze-lined metal or stone crocks, provided prepared syrups or extracts may be retained in the original containers in which they were delivered. Such containers shall be covered at all times.
