KIRBY , WRIGHT & Co : PORTER 1865

 How Do All , 

Here`s a classy Porter from the earliest known commercial brewing record in a public archive from a Sheffield brewery , the Brewing Book of Kirby , Wright & Co 1865 @ SHW 6/1/2/1, deposited with the team at Sheffield City Archives on Shoreham St .

The brewing book of Kirby , Wright and Co does contain various details such as Malts & Hops used and Gravities , sadly it  doesn`t record brewlengths and only rarely does it record the initial liquor heat. 
a similar situation exists with the attenuation and yeast use records , though these are , sadly absent .
The records at the end of the book are from the time immediately before Septimus Ward`s purchase of the brewery outright in 1871 ; Happily these records do include ( occasionally ) some mashing and other details which have allowed me to extrapolate the brewlength yields and collection gravities used in the Kirby , Wright & Co beers .

 The Sheaf Island Brewery was established in 1837 by William Roper & John Kirby , with           George Wright joining the business in 1861 ; the partners were joined by Septimus Ward in 1868 .            Septimus Ward bought the business in 1871 and in 1876 , the entire concern removed  to the            Soho Brewery of Bradley & Co , shortly after it`s purchase in 1876,  it was Re Named
" The Sheaf Brewery " , continuing to brew until 1999  when it regrettably ceased brewing  . 

If any blog readers know of any Brewing Records from Sheffield or other South Yorkshire and other UK breweries ; I would really appreciate access to any surviving records , and where access is possible, please leave a comment below or a message through the blog contact form ,                                          I`ll respond as soon as possible .
