The difficulties of getting alcohol from a starchy substrate is one of the reasons that brewing is much more complicated than wine making. When the vital
malting stage is factored in it's a long and involved process. Sake
making doesn't involve malting but is just as convoluted.
There is however another, simpler, way of getting fermentable sugar from starch that is used to make
Chicha de Muko: chewing grains and spitting them out. Not the most appetising way of making booze but saliva contains an amylase enzyme so the science is sound. I decided to give it a go.
I got a load of corn on the cob when they were reduced in the supermarket and separated the kernels.
Then I got on with the chewing and gobbing stage.
You're then meant to make balls of the chewed maize into cakes and leave them for a day, but I hadn't let the grains dry out enough so it was quite sloppy. I left it for a day and after that it smelt like it was starting to ferment already. I added hot water until the temperature got to 65°C to hopefully help any starch breakdown complete. This made things more dilute than I would have liked with a gravity of 1.020. I guess I should have heated the mash.
When it had cooled I pitched some brewing yeast and after a day there were small but definite signs of fermentation.
A day later they'd subsided though so I guessed it was time to drink it.
My first attempt at scooping out the liquid left me with more bits than a North Eastern IPA so I poured it though a sieve.
This gave me something that I wouldn't have to chew again. The taste was slightly sour and decidedly savoury. I had a couple of glasses which went down easily enough, but there wasn't enough alcohol to have any noticeable effect. I really should give it another go and try and make it stronger but I'm not sure it's worth the effort.
