ROBERT MEIKLEJOHN & Co : 72 / - PALE ALE 1873

How Do All ,

Here`s another tasty recipe from Scotland for you all to try ; taken from records in the collections of,           The Scottish Brewing Archive at Glasgow University Archives Special Collections                                   Website Address : https://www.gla.ac.uk/myglasgow/archivespecialcollections .                              I`ve interpreted the recipe from notes in The Brewing Notebook of Robert B Wallace 1873 - 1884 @ MJ 6/1/1 .
This notebook contains not just brewing notes and calculations relating to Meiklejohn`s 
(*Though annoyingly no attenuation details for the Pale Ales ! ) ,  but also other details with quite a few notes on Irish breweries ; such as analyses of X Porters from both Findlatter & Co and Phoenix Breweries in 1884,
Findlatter`s X Porter : Original Gravity @ 1.057.9 ; 5.9 % A B V 
Phoenix X Porter :      Original Gravity @ 1.058.2 ; 6 .0 % A B V  

Anyroad , without further delay ; Here`s the recipe ( With my approximation of attenuation points )🍻
