LOL I had to stop and think for a second on that.
Since I have 3 two liter bottles of a wine making experiment where you have balloons on top for the air-lock - when the balloon goes up, the yeast is working - when the balloon goes down, the wine is ready!
First thought was hey another balloon wine maker - wonder how it works for them...
My folks made wine that way. Welch’s grape juice concentrate, sugar, yeast, water. Into a big jug with a big balloon on top.
That was some wicked stuff. Sort of like Mad Dog 20/20 when it was done, LOL!
What I was talkin’ about:
‘This expression comes from World War I, when British artillery sent up a balloon to notify gunners to open fire, this visual signal being more reliable than courier or telephone. It was soon transferred to signal other kinds of beginning. [1915]’
I'm wondering if detailed instructions for the balloon method for wine are posted somewhere. I missed them if they are, I tend to get spells when I'm too busy to read this.
That used to be the preferred method for the home wine making IIRC.
