Late 19th-century IPA

Where to go from early 19th-century IPA? Late 19th-century, surely. Examples plucked, once again, from brewing records. That most useful of resources. To increase the fun, a Canadian brewery us represented, in the form of Labatt.

The Whitbread beer is an outlier, a beer, us the name implies brewed under contract, presumably for export. They didn't brew an IPA for the domestic market for another three decades. Which probably explains why the hopping is so much heavier than in the other examples.

Talking of hopping, it's mostly 50%, or less, in terms of lbs per quarter of that in the early 19th-century IPAs..

On the whole, they look pretty similar to the 1840s analyses. The average OG is a little higher, balanced out by a much lower degree of attenuation. With the proviso that these are racking gravities and not the eventual FG.

Compared to the couple of brewing records from the early part of the century, the gravity is quite a bit lower - 6.6º. Though the earlier sample size is low.
