An extra bottle for the iSi Twist'n Sparkle Virtuoso makes it possible to have one bottle chilling in the refrigerator while the other is in use. It is a practical arrangement since the carbonation effect is stronger the colder the drink is. The same carbonation rod is used for both bottles and is only changed when it is time to fill the next round.
The bottle holds 0.95 litres and is made of PET plastic with a silicone sleeve. It is compatible with both the Twist'n Sparkle Virtuoso and the older Twist'n Sparkle. It is suitable for cold drinks such as water, juice, tea, wine (at your own risk) and spirits, but not for hot or thick liquids. Hand wash only.
The extra bottle is available in four finishes: Onyx, Sage, Lilac and Ivory White. Different colours in the household make it easy to keep track of whose drink is whose.
