Time to look at some Light Ales in more detail. That most unfashionable of styles.
There’s not a great deal of variation in the gravities: only just over 3º. Which isn’t a great surprise in beers of such a low gravity. Though there’s a way larger spread in ABV, due to hugely differing degrees of attenuation: from 66% to 91%.
This leaves alcohol levels varying from 2.6% ABV to 3.9%. Which, considering the beers were a similar price, means some were way better value than others. With the weakest being barely intoxicating.
A lacking of consistency is also evident in the hopping rates. The highest, 7.5 lbs per quarter (336 lbs) in the Adnams example, is Almost double that of Eldridge Pope’s beer. Though that isn’t totally reflected in the IBU level.
Speaking of which, the values in the table are calculated with brewing software and so should not be taken as gospel, more a general indication. As there are too many unknown variables in some brews, such as the variety and age of the hops.
Similar caution should be taken of the colours, most of which, again, are calculated via brewing software. Only the Boddington and Truman values were taken from the brewing record.
