Strip Runs
3l per strip run to allow for puking, collected to a volume of 1 litre. Due to work constraints I have to use a time based solution. (this was 4.5hrs) I have a 220v AC supply, this means my Airstill is operating at around 280w instead of the 320w with a 240v supply.
Managed to get 11 runs at 3 litres each. Final run was very cloudy but passed with no issue.
Stripped Quantity was 11 litres at approx. 22%.
Due to the constraints of the Airstill and wanting to follow Harry’s Glenmarongie Cuts I had to carry out a “spirit strip” run. Basically I charged my still with 3 litres of strip and distilled it, no cuts to an output of 10%.
This produced 1.40 litres at approx. 45%.
Spirit Runs
Using Harry’s guide I fully charged the still 4 litres - 60/40 with strip / spirit strip.
Again using a mix and match to keep as close as I could to the guide I wanted emulate I cut as follows:
Foreshot - 50ml
Heads – down to 75% ouput
Hearts – 75% - 60%
Tails – 60% and below
Heads and Tails from each run were immediately recycled into the spirit with the 60/40 being relaxed.
Final output was 2.00 ish litres at 67%
Aging
The spirit has been cut to 56% and is currently on oak. 10 grams per litre. It is taking on a beautiful amber colour with a distinctive vanilla smell.
It is my intention at monthly intervals to cut to 48, 44 and finally 40. The spirit will be left to rest at 40% for a further month before bottling and consumption.
Wrap Up.
Would I do this again? Certainly would. The output by volume is not large but the aroma is fantastic. Just because it's an Airstill doesn't mean you can't play with more than sugar and essence.
I didn't have a clue what to expect and I still don't know what the flavour will be like. From aroma alone it smells like an Irish Whisky more than a Scotch.
