Welcome to AD Rob.
Bakers yeast is fine.
Yield calculations are difficult without knowing the alcohol content of the wash but assuming something like 10% that gives you 2.5 litres of alcohol to start with and given you can’t recover all the alcohol from the wash then what you have seems about right.
I would suggest reading the thread on cuts in Newbies Corner to help you get better results as not everything you collect will be useable; you’ll see the terms “fores”, “heads”, and “tails” mentioned and these are important to learn about.
“Generations” is where you take the remaining liquid left in the still after a run (aka backset) or the yeast bed left over from fermentation process (aka trub) and use them to start the fermentation of the next batch to produce a more flavourful result. You would usually add more of your ingredients on top of this and yes there could be dead yeast in there.
You would normally not add a flavouring as you would age the product on oak for a good enough length of time to introduce the colour and flavour you desire. Having said that, it seems like you’re trying to make whisky with a reflux column. This will not be terribly successful as reflux columns are designed to strip flavour so you’re not getting the benefit of the grain flavoured wash. Some folks have added flavourings then oaked the flavoured results but I’ve not had any experience with that as generally I don’t make brown spirits.
A stripping run is where you take a wash and run it hard and fast through pot still to create what are called “low wines”. You generally run it until it becomes no longer viable to do so; some people stop at %20 others a bit lower or a bit higher, that’s just personal preference. It is used as part of a strip/spirit run strategy and can improve the quality and quantity of your hearts in the spirit run, especially if you combine the results of two stripping runs to create a larger still charge for the spirit run.
Hope this helps.
