I spend a few seconds each day riddling. My current science experiment is these two bottles of homemade champagne. Champagne starts with fully fermented wine, before it's bottled and before you put in chemicals (potassium metabisulphite) to stop the fermentation for good. Put the wine in a sturdy Champagne bottle, a little sugar (the dosage), a little yeast, then seal it up and set aside for in-bottle fermentation. After the yeast has done it's stuff (made lots of carbon dioxide for bubbles) you begin the task of riddling. Riddling involves storing the bottle at a downward angle (a plastic bucket in this case) and giving it a small turn each day. The goal is to get the yeast sediment to all slide down into the neck of the bottle.
Stay tuned: next month, disgorgement!
So I wrote a little tune, it goes like this...
Biogas Hillbillies
(with apologies to Flatt & Scruggs)
Come 'n listen to my story 'bout a man named Fred
A poor Vermonter, barely kept his family fed
And then one day, he was a-milkin' the herd
And out through a cow come a gaseous turd
Methane, that is, beano gold, cut-the-cheese
Well, the first thing you know, old Fred's a bioengineer
Kin folk said, Fred, think anaerobic plug-flow digester
Said, sellin' back to the grid is the place you oughta be
So he loaded up the fermentin' bags and started generatin' AC
Alternatin' Current, that is, spinnin' motors, lightin' streets
Well, now it's time to say goodbye to Fred and all his gas
He would like to thank you folks for kindly droppin' past
You're all invited back again to this locality
To have a heapin' helpin' of compost, free
Highly processed, that is, no smell, sweeter than feet
Y'all come back now, hear?
