How Do All ,
Today`s recipe is a beautifull Porter from 1894, One drawn from my recent trip to
The Oxfordshire History Centre in Cowley ; An analysis of , The brewing books of A J Baily
whilst he was brewing at Brook Street from early 1894 , Until early - mid 1897 .
This recipe comes from the only one of the trio of books to contain attenuation records , the earliest of the set which only covers the period between January and October 1894
@ B 33 A 13 1 .
The original grist for the mash was relatively simple , containing imported Russian barley ,
Malted in the UK @ 8 Quarters; And a malt entered as " Gray " at 4 Quarters ; then 3 quarters
Each of both Crystal and Black Malts .The Sugars originally used wer a blend of Graton`s ,
" Caramelised " ; and a common ingredients in quite a few stouts & porters of the period , Caramel .
The Hops used were a blend of both UK ( Sussex 1893 , and Falmouth Kents 1893 ) ;
And at the start Of the boil , Oregons 1893 .
Cheers All and Happy Brewing ,
