WILLIAM TETLEY & SON : DUBLIN PORTER 1833

 How Do All ,

Today`s recipe is taken from the the earliest known Tetley`s Brewing Book ; the tome covering the period from 1833 - 1835 contained within  ACC 2412 Box 57 , Part of the larger Tetley`s archives , cared for by   the ever helpfull and friendly folks at West Yorkshire Archives , Morley .

The brewing book merely contains the gross weights of ingredients used , barrels & gallons of Wort and Beer ; Usually with the average Original Gravity stated in the individual brewings . On occasion this is absent which meant I had to use the average whole gallons of wort & gravity of each ` Copper ` in order to derive the gravity ; Original or otherwise and the ` Barrels & Gallons ` of wort at Collection in Copper and in Fermenting Vessel .as a whole gyle in the case of this beer which is only entered once in the entire period covered by the 1833 - 1835 Brewing Book ; which was written up by the Grandson of William Tetley and son of Joshua, Francis William Tetley .

I hope that you all enjoy the recipe , It`s one for 22.230 Wort Litres to the F V and 21.600 Beer Litres to the Maturation Vessel ON Primings .

I`d appreciate it if readers could help with a current project ; 

One my research projects is trying to trace ( & Access ) production records from defunct breweries formerly located in the North of England which are in private and corporate archives , 
This is to gather materials for a book on the beers, brewers & breweries of the north of England from the earliest Commercial producers to the period up to 1968 - 1970 . 

If you`re able to assist with my research , get in touch with me @ beerhistorybloke@gmail.com

Cheers All and Happy Brewing ,
