"Jesus, I had to laugh at the way he came out with that about the old one with the winkers on her, blind drunk in her royal palace every night of God, old Vic, with her jorum of mountain dew" (U12.1393)
'Mountain dew' is a slang term similar to 'moonshine' = home-distilled alcohol, especially where illegal. It is made from local products such as corn, potatoes, grapes, cane sugar etc. Irish mountain dew (aka as poteen), was potato based.
