Whats your output at the 85% and is the Abv dropping or sitting at the 85%?
My only thought was whether or not you've got a bit of flooding in your packed section from it being too tight? :think:
Hey Dan, Its was steady at 85%, but after the foreshots I have been able to get it to 90% and its pretty stable at that.
I reckon your right. I might have bumped the 500ml packed section when putting it on after the stripping run.
Output is about 2.5 litres a minute (drip drip dribble) for the foreshots and 2.7 litres for Heads etc (pencil line)

Glad your getting it sorted.. try slowing down to 2l/hr or below, you might get Abv a touch higher. :handgestures-thumbupleft:

I realise your most likely using the mesh as a retainer for the rocks, but i recon it would be worth your time to make that change possible
gawd i need a new keyboard, my r is shot

Its certainly giving me the sh**'s :text-lol:
I can possibly live with 85%, but its frustrating when I have never had an issue and I haven't changed anything.

Yeah blame the virus.. it seems to be the cause of all our problems atm, not the pollies. :laughing-rolling:

I can get 85% out of my 1" with 4" of scrubbie, try harder :))
Ned wrote:I noticed also wattage on the bottom element is down to 2200 watts (2400 watter) I only use the bottom one when doing a spirit run, not sure if this would make any difference,
might try putting the 2nd element on at 25% to see what happens

When i first built my bubbler i had trouble with a dropping Abv through a run, much like a pot still.
In the end it came down to not quite enough reflux and in part running it outside in the cold night air. Too much heat was getting lost. Needed more heat.
Now i run a 2400w element flat out and the other partially on with a volt controller.
Perhaps your element isnt doing you any favours here either?

Hey Dans.brew :text-+1:
Thats also been the train of thought as the element has lost 200 watts in punch, so might try the 2nd element at 25%. Just need to change one thing at a time otherwise you loose track of what the final result is. Couple of things to work on. Can't do much else until "Dan" opens up Victoria.
