THOMAS USHER & SON Ltd : PALE ALE 1936

 How Do All ,

Here`s a nice Session Pale Ale from Usher`s of Edinburgh from the 1935 - 1936 Brewing Book ,
Catalogue No : TU 6 / 1 / 7 , Part of the Scottish Brewing Archive ; Cared for by the helpful and friendly team at The University of Glasgow Special Collections & Archives on Thurso St , Glasgow .

I`ll be posting more about this brewery`s beers and history in the coming months ; 
Whilst I was sorting through the Usher`s photos I thought that this little belter of a Pale Ale would make a tasty session beer for you all to try out .
The Mashing regimen for Usher`s includes the Mash Heats but sadly omits the finite Liquor volume used  ; a feature present as Wort in the Coppering / Boiling , though as this beer is a Parti Gyle the Copper Lengths and Gravities are radically different for a ` Single Gyle brew ` ; So whilst the Initial Hop Charge Gravity is a Constant 1.031 ON BOTH BEERS , and the Liquor Back Gravity @ 1.039 are CONSTANTS , the major difference is the ammount of Liquor added to the Copper to Liquor Back to the required gravity @ *  ( * =  desired gravity ; allowing the addition of Copper Sugars )  . 
 Some of the Usher`s brewing records stipulate the individual Hop Charges , though a universal feature is the Hops / Qtr of Malt ratio , which in the case of this Pale Ale and it`s bigger brother in the Parti Gyle ; 60 / Pale Ale ( 1.040 ) was at a modest 6.5 Lbs per Quarter , Yielding 292.5 Lbs to the Copper and , 58.5 Lbs / 936 Ounces for Racking Hop Additions ; Though these vary in rate , from 2.5 Oz/Brl in 1936 for the Pale Ale to 3 Ounces / Brl in the 60/- Pale Ale of the same brewing .

I hope that you all enjoy the recipe ,
