Upon one of my latest travels through the internets. I came across what is referred to as the ginger beer plant. Used for the traditional production of ginger beer (go figure), GBP is a composite organism consisting of Saccharomyces florentinus, and Lactobacillus hilgardii.
I had never heard of either organism, and them internets didn’t pony up much data. So, for science I decided it was my duty to attempt to cultivate said organisms.
The information that does exist about growing a GBP is unfortunately for the most part written by hippies. Generally very nice people, but have the habit of making OCPD brewers like myself cringe with the lack of reliable information. As an aside, I would like to say: hippies, the scientific method is your friend. Do not fear the method. It is a tool, not an ideology. At the very least, please list your ingredients in weight rather than in volume. If you don’t own a gram scale, you probably have a friend that does.
Using a recipe for a GBP starter taken from Wellness Mama, I extrapolated a 25ºp solution was built up over the course of a few days. The reason I assume for the stepped additions is due to the low nutrient environment for organism growth. I figured rather than waste time feeding the starter over the next 5 days, I would jump the gun and provide those lil’ organisms the proper environment for healthy growth. That is right, cocksucking beer wort! None of this white sugar - water solution shit. More FAN than you can shake a shaking stick at. Working with approximately half the plato (11.8ºp), but four times the volume (1.89 l), 6 pieces of ginger seemed appropriate. Granted, the requirement of 6 pieces was generally pulled out of my ass due to the original recipe.
I FUCKEN HATE PSYTRANCE ginger bug starter
1.89 litres 11.8ºp wort
513g grated ginger
can florentinus and hilgardii ferment maltose. find out next time, same shat-channel same shat-time?
Transferred sterilized mason jar, and took gravity. FG 2ºp
experiment verdict: SUCCESS!
Flavour: ginger spice, yeast bite, and lemon. Which ought to be pretty obvious.
