How Do All ,
Apologies for the lack of posts recently ; I`ve been finishing an analysis project of a Yorkshire brewery`s Brewing Book from the pre Great War era , more of this soon !!!
(The sole surviving Brewing Production Record to my knowledge
Anyway , enough badinage , Here`s another superb recipe from an Edinburgh brewery ,
Drybrough & Co Ltd at Craigmillar , which was built in the early 1890`s on a greenfield site .
Sadly none of the early ( Pre 1906 ) Drybrough brewing records have survived in public archive from the company`s operations Tollbooth Wynd or , after the move to the North Back of Cannongate in 1782 , or after the expansion into the neighbouring Craigend Brewery in 1874 , so if you`re able to help locate these rec ords ( If they Survive ) please get in touch , I`d love to hear from you .
This recipe comes from the Drybrough & Co Brewing Book 1906 - 1910 @ D 6 / 1 / 1 / 1 ; Held in the internationally important Scottish Brewing Archive at Glasgow University Special Collections & Archives , Thurso St .
