The village consists of the Twice Brewed Inn, a combined YHA youth hostel and  Visitor Centre to the Northumberland National Park ('The Sill'), and also some farms.
One of the farms is a bit further away, and is called "West Twice Brewed" on the Ordnance Survey maps.

Both the Twice Brewed Inn and the youth hostel are popular sleeping places for walkers on the Hadrian's Wall Path and the Pennine Way.

The village of Iverton, which appears on 18th-century maps of Northumberland and latterly in two probate records from the 1830s, appears to have been coextensive with, or in very close proximity to, Twice Brewed.
 R. G. Collingwood, writing in 1921, identifies Iverton with Everton, a "ruined farm half a mile west of Chesterholm", or roughly the distance between Chesterholm and Twice Brewed.
 No farm of that name appears on Ordnance Survey maps from the 1920s or earlier, however.
 It is possible that the name of the Twice Brewed Inn gradually became attached to the buildings around Everton as the latter fell into disrepair.

The same maps place 'Forsten', another no longer extant Northumberland village, just across Bradley Burn from Once Brewed.
 Collingwood's identification of Forsten with Fourstones near Hexham thus appears to be mistaken.
