That hasn't stopped League Two newcomers Bonnyrigg Rose being rewarded with a big tie against fellows Lothians side Hibs, a repeat of a 2017 Scottish Cup clash. The Easter Road side ran out 8-1 winners that day at Tynecastle Park.
They are joined by Greenock Morton, Falkirk and Clyde.
Aberdeen, having avoided the group stage with consistent European qualification, are competing in it for the first time since the reconstruction of the League Cup. They will have a local encounter with Peterhead, as well as matches with Raith Rovers, Dumbarton and Stirling Albion.
The teams will face their group rivals once with the eight group winners and three best runners-up joining Scotland’s five European entrants – Celtic, Rangers, Hearts, Dundee United and Motherwell – in the last-16.
