Let's Brew Wednesday - 1845 Reid Keeping Double Stout

OK, you went for 1830 to 1860. So here you go. A beer from smack in the middle of that period.

This and the previous beer are a great example of the difference between Running and Stock versions.

In most respects, the beers are identical. The grists are identical: 112 quarters of pale malt, 18.375 quarters of brown malt and 5.625 quarters of black malt. The only tiny difference is that the pale malt quarters were 340 lbs rather than 344 lbs.

This similarity extended even to the mashing scheme. The quantities of water and strike heats for the two mashed were identical. The only differences are the tap temperatures, which are lower in this case. That could be because the ambient temperature was 7º F cooler when the Keeper was brewed.

Mash number barrels strike heat tap heat
1 296 165º F 144º F
2 282 178º F 158º F

The one area where there were significant differences between the two Double Stouts was in the hopping. As you’d expect, the Keeper received more copper hops. 28% more to be precise. Exactly the same types of hops as in the Runner: English from the 1843 and 1844 harvests.
