No other size bottle of spirit quite has the presence of a 4.5L bottle. These bottles are great for parties, events and get-togethers and can be quite a talking point. A 4.5L bottle is also known as a Rehoboam and is equivalent to approximately 6.5 standard 70cl bottles. The name 'rehoboam' comes from the Biblical story of King Rehoboam, who is said to have ruled over the Kingdom of Judah in the 10th century BCE. According to the story, Rehoboam was offered the advice to 'rule your subjects with a light hand' but instead chose to rule harshly, leading to a revolt and the division of his kingdom.
