This is a large wine bottle with a globular body, short tapering neck and an annulated neck ring. Bottles like this and often larger, were made over a long period of time and were probably for moving liquids, including wine in quantities larger than one could in a standard bottle. We have not (yet) measured its capacity, but would expect it to be about 4-6 bottles. Such bottles are sometimes known as 'carboys' or 'demijohns' - a name today given to large bottles often used for fermentation.
The bottle is dark olive-green and has a large broken (i.e. not polished) pontil. We feel the bottle dates from somewhen betwen 1750 and 1830 but the wear to the base suggests a date in the earlier part of our dating, say c.1780.
