I think if you doubled everything but the yeast it would last longer. If I remember right the yeast multiply until they run out of oxygen, then the stop reproducing and create CO2 among other things.
The yeast slows production of CO2 when the alcohol percent reaches deadly levels, and they start to die off, so if you have the same amount of yeast but twice the amount of solution they should be able to live longer.
Now that I think about this I’m thinking about changing my one bottle system over to a two bottle system but with half the yeast in each, and have a tee connecting the two before the tank. And in effect make them last twice as long, if not close to it. |
