REPORT ON THE MALT LIQUORS SOLD IN THE UNITED KINGDOM:
WITH ANALYSES AND COMMENTS.
IV.—Mild Ale And Old Ale.
The kinds of malt liquor represented by the analytical results given in the following table differ very much from what is commonly known as pale ale or bitter beer treated of in the former report,* independently of actual strength or of the peculiar flavour and bitterness given to pale ale by the large proportion of hops used in brewing it. Mild ale is generally characterised by a sweetness more or less decided, indicating the presence of sugar. In old ale, this character is less obvious — partly owing to the presence of free acid, which masks the sweet taste. The difference between pale ale and these two kinds of beer is further indicated by the amount of extract in mild and old ale being, as a rule, larger, relatively to the alcohol, than it is in pale ale. This difference is chiefly due to the way in which the fermentation of the wort has been conducted, and to its being carried further in one case than in the other.
In regard to the actual amount of alcohol in beer of this kind, it varies in mild ale from 4.41 to 7.34 per cent, by weight, or from 1.1 to 1.75 fluid-ounces of absolute alcohol per pint, the average alcoholic strength being decidedly above that of ordinary bitter beer. In old ale, the amount of alcohol is still larger, varying from 6.2 to 8.41 per cent, by weight, or from 1.5 to 2.75 fluid-ounces per pint of the beer.
The amount of extract in mild ale varies from 3.58 to 6.81 per cent, by weight, or from 0.75 to 1.5 oz. per pint of the beer; and in old ale it is from 4.56 to 13.32 per cent, by weight, or from 1 to 2.75 oz. per pint.
The amount of free acid taken as acetic acid is in mild ale from .13 to .28 per cent, by weight, or from 10.5 to 24.7 grains per pint; in old ale, it is from .16 to .56 per cent, by weight, or from 14 to 49.4 grains per pint of the beer.
The quantity of malt used per bushel in the brewing of these samples of beer, as indicated by the estimated original gravities of the wort, varies in mild ale from 1.77 to 3.2 bushels per barrel, and in old ale from 2.69 to 4.5 bushels per barrel.
From the great alcoholic strength of some samples of old ale, they partake more of the nature of wine than of beer, in the usual sense of the term. They are, in fact, quite equal in that respect to most of the cheaper wine imported from France, Germany, and Italy; while, in flavour and general character, old ale such as that brewed at Burton and in Scotland is far superior to any wines of the kind referred to, which can be sold here at a price double that of the best old ale. This kind of beer, however, is but rarely sold at public-houses.

That first paragraph is very revealing. Particularly in regard to the differences between Mild Ale, Pale Ale and Old Ale. Notice one thing that isn't mentioned? Probably the first point that would me mentioned today were someone to describe the difference between Bitter and Mild. Colour. Because in 1870 all three types of beer were brewed from 100% pale malt (optionally with some sugar). Pale Ale, for which the best and palest malts were reserved would have been a little paler than an X Ale, but not a great deal.
