Notes

Constable McGrath was a fine officer in Thursoe Scotland who I met on a single track road in the northern highlands. After a motor accident where I was run off the road, he helped me and got me on my way. I will always be grateful to him and his fine and generous character. God blesses you, Constable McGrath.

Adding Brett Bacillus and old stinky cheesy smelling hops to a classic ESB Recipe....The BrettBac was barm from a previous batch of Belgian Bretty Boop which I fed and nurtured for a couple of weeks. Hoping it turns out like a 17th-18th Century tavern ale....but how would I know....oh well.
