Unusually sober South Africans (5)

I believe the answer is:

boers

'south africans' is the definition.
(Boer is an example)

'unusually sober' is the wordplay.
'unusually' is an anagram indicator.
'sober' with letters rearranged gives 'BOERS'.

(Other definitions for boers that I've seen before include "Robes for S African rebels" , "Afrikaners who fought two wars against Britain" , "Dutch-descended South Africans" .)

I've seen this clue in The Globe and Mail.
