Introduction
Beer brewing is as much an art as a science. Finding the right blend of delicate grains, hops, malt, adding just the right flavoring agents, boiling for exactly enough time to release the tannins, starches, humic acids from you wort, these are all skills that take a lifetime to master. Perfect beer is meticulously planned and carefully crafted.
Screw that.
You’re six days into a 2 month expedition, and if you were lucky enough to not be on a dry ship, it’s de facto dry by now anyway. You’re eying the ethanol stores, the crew is eying each other, and all hell will break loose if y’all don’t get some sweet water soon. This is no time for artistry.
This is not, as a rule, a terribly good beer (though, with a good brewmaster on board, it can be). This is a beer to pass the time. I can guarantee that if you are careful, it will be at least as good as the cheapest commercial alternative.
