MAPPIN`S OF ROTHERHAM : CORONATION BEER 1937

  How Do All , 

Some folks have been asking if I`ll be posting a special recipe to mark the occasion of the Coronation  
Well the simple answer is yes , and here it is.

A beautifull Coronation Ale from Mappin`s Old Brewery in Rotherham from 1937 , I hope you all enjoy the recipe ; It`s taken from 1937  brewings , Transcribed from the original records by a former brewer and  copies of brewings of this , B B ; S.B , Mild and I P A kindly sent to me some time ago by a Yorkshire based historian .

The original beer used Malt from local Maltster`s Robson`s ; Mild , Pale and Californian Malts &
 2 Quarters of Flaked Maize in the grist; with an addition of Malt Extract @ 2 Cwts(224 Lbs/1 S Qr ) then to the Coronation Beer 8 Cwt / 4 Qtrs No 2 Invert which equates to 1.009.25 degrees . 
( From a total No 2 Invert weight used in this brew of 12 Cwt / 6 Sugar Quarters ) 
The Hops in Copper were a fairly typical make up of Kents " Edwards K 35 & Piper K 35 " with a mysterious interloper in " Haywards? S 36 " and a surprise in the shape of the inclusion of " Styrian 36 " as a Copper Hop towards the end of the boil ; this Hop is also the Racking Hop , Originally at a whopping 3 / 4 Lb Per Barrel ( 12 Oz ) 

I hope you all enjoy the recipe , I`ll be posting a few more from this source in the next week or so ; though there`ll be a break in the Yorkshire Beery History posts with a special recipe for you all on Tuesday from Scottish Brewing Archive source materials .
