How Do All ,
To finish off the series of Mild in May recipies , here`s a beaut of a Scottish Mild Ale recipe from the Edinburgh brewery of T & J Usher . It`s taken from the earliest known T & J Usher brewing book ,
TU 6 / 1 / 1 : Brewing Book 1885 - 1893, which forms part of the internationally important Scottish Brewing Archive , Cared for by the ever helpfull team at The University of Glasgow Special Collections & Archives on Thurso St .
The firm of J & T Usher had been brewing at the Cowgate Brewery , Campbell`s Close in Edinburgh from 1831( Previously operated by : David Aikman & Co 1817 - 1828 and by Hutchison & Aikman 1828 - 31 ) .
The brewery , founded by James Usher and a Mr Cunningham continued as a partnership until 1839 , when the business was styled Usher & Co and by 1843 , the firm was known as J & T Usher .
The company continued at the Cowgate premises until 1860 when they removed to The Park Brewery on St Leonards St and was registered in March 1895 as Thos Usher & Son Ltd to aquire the business of J & T Usher .Thos Usher & Son Ltd continued to brew independently until 1959 when they were purchased by Vaux of Sunderland who changed the name to Usher`s Brewery Ltd in 1972 , with the Park Brewery being operated by Lorrimer`s from 1976 until the brewery was bought by Allied Breweries in 1980 ; With brewing ceasing in the following year , bringing to an end 121 years of Usher`s beers at the Park Brewery.
The brewing books from Usher`s do have a great deal of valuable technical information therein contained , though annoyingly no Liquor used in the mash expressed in Barrels ; so the Mashing and Sparging perameters are , my own based on period practice and personal interpretaion of the records, as are the attenuation perameters ; On an allied note , I have altered the racking gravity to suit a modern container type .
