Botte, (plural ‘botti’) Italian term defined by Nicolas Belfrage MW as a large wooden cask or ‘wooden barrel of wide-ranging capacity, from around 10 to 100 hectolitres or more; traditionally chestnut [‘castagno’], or, more recently, of oak from Slavonia, more recently still of oak from France,’ and presumably from the same root as butt (Oxford Companion, 2015).
