Hey Wellsy,
Looks like I read to much into the stripping spirit run comments lol.
I'm only a beginner, but I did the same thing - I read everything I could find about cutting, and stripping (and not the de-cladding type... I'm not that type of gal!) and have learnt a few things over the past weeks - my extensive distilling experience :D. I have a little 4L airstill - is that what Sam has? If not, this may not apply.
- Most of the time, heads don't seem to be make a diff, BUT the airstill can switch to tails very quickly on some runs. So I pay far more attention to tails than I do heads. Past 800ml I keep testing in small batches just in case. Sometimes goes sour/bitter at 800-900ml, other times ok to 1100ml (or occasionally beyond). I do test heads on spirit and final runs, but most of the time I use once I've checked smell (and taste if game!) against the next 500ml or so.
- Chillax when it comes to the stripping run. Just let it run, watch for real nasty tails, but don't stress too much. I tried both severe and small cuts for the stripping run but worked out it doesn't really matter. I just don't try to push it too far.
- I've accepted that a triple distill is required to get a decent neutral with 4L airstill. I dilute down to 20% ABV each run (I read on here "less flavour in, less flavour out").
- I started with Turbo Trio/Yeast (as per manufacturers instructions!) and it was terrible. TPW was heaps better, but still had a hint of tomato after triple distill and filter. WBAB was the best so far. It produced better than 'just drinkable' vodka - actually pretty good after triple distill. Have a FFV wash on now, but it'll be a week or so before I can report back.
I'm still using my ceramic saddles each run, just in case (my mother is a ceramic artists - perhaps I'll get her to make me a bunch more for the future!).
I hope that helps in some way. I'm grossly under-qualified to be shedding out advice but thought my "notes to self" might give others something to work with.
Cheers,
RR
