So after many months of "preparation" I finally ran my first spirit run on my 50 lt alembics whisky still
2 wash runs of 12.5 kg distillers malt fermented with safspirit M1
38lts in the boiler @ 30%
collected 7 jars @ 250ml,20 jars @ 800ml- 78% down to 20%
collected & tossed first 250ml
initial take off 720ml/hr for first 1.7lts raised to 1.4lts/hr
slight tails evident @ 64%, jar 18 off the still
aired for 24 hours
kept jar 7 @ 78% to 17 @ 68%
observation
I had great difficulty determining heads / hearts cut , no nasty flavours or chemical/acetone in early jars
tails very distinct and in my view a large % of return
1.4lt heads
7.2 lt hearts
8lts tails
this still is difficult to run slow, with the worm & tub condenser I find it huffs in around 1 second pulses early in the run & settles under power & later in the run
have tried hot water in the tub & appears better than cold tap water @ 18 degrees
interested in your comments team ;-)
