In Scotland there would still be a number of pubs around which have a jug bar. It is usually a small area screened off from the rest of the bar with its own door to the street. There is a small hatch in the panelling to the bar staff on the other side.
Jug bar? Where you send the child with the jug to be filled up with "heavy" for drinking at home. And while in the jug bar the child cannot see all the sinning that is going on in the main bar!!!
In Scotland too there are other terms for their beers: 60 shilling, 70 shilling, 80 shilling and very very occasionally 90 shilling. This refers to the ammount of tax levied (long long time ago) on a barrel of beer depending on its strength.
60 shilling or "light" is actually very dark in colour - almost like Guinness but light in alcohol content about 3.2% 70 shilling or "heavy" is the equivalent of an English bitter but not so bitter usually; about 3.9% alcolhol. 80 shilling is like an export or India Pale Ale - IPA is the only beer that was able to last the trip out to India to water the troops in days gone by! It would be about 4.5% alcohol And then 90 shilling. Very rare, a bit like a winter warmer. Strong and quite sweet at about 7% alcohol.
Wow! all this info on Scottish beer from and Irishman!
