How Do All ,
Today`s beery delight is dramn from the basic information given in the source named below .
Unhapilly , the Diary of Brewing for 1858 doesn`t contain any attenuation or , Pitching
And Attenuation details , so I`ve used both research and period records to approximate what ,
I believe would have been the ` Missing Link ` in re the fine details .
One other point of note is , the use and calculation of the Black Malt proportions in the grist ;
Black Malt wouldn`t have had an Extact Poundage of say 86.7 Lbs/ Qr ;
So I`ve altered the grist proportions for the recipies calling for it`s use to reflect this ;
Given a Hypothetical Black / Patent Malt Lbs per Quarter of 48 - 50 , draging the proportions
To be used to a respectable 2.5 % on average accross all analysed brewings of Porter .
As some eagle eyed viewers will no doubt notice , I`ve included a ` Theoretical ` Malt ;
A FULLY DIASTATIC Brown Malt @ an average Extract @ 85 % Mash Efficiency of 250 L/D .
The information is drawn from the Courage Diary of Brewing 1858 @ ACC 2305 / 08 / 274 ,
Part of the Barclay, Perkins /Courage & associated companies archive ,
Cared for by the ever helpfull team on Northampton Rd at The London Archives .
