make any difference to the ethanol. What will make a difference is
if there will be enough depth of liquid pooled on the bottom of your
boiler to prevent scorching and hot spots. Once the ethanol
is 'made' in the fermentation sequence, you can add any amount of
water to make up the depth you require.
You could scale it up easily enough. Just be sure to only fill the
boiler about 60 percent if you intend to distill on the grains. Or
else you will encounter a foaming problem clear up into your lyne
arm. No matter how full you fill the boiler it will foam up. Even if
you take the wort off the grains it will still foam up.
Only fill your boiler up to near capacity if you are working with
liquid that has already been distilled.

for cleaning purposes, it should work just fine. As you know, when
you mash grains, it becomes a thick porriage at one point. Also
after the fermentation, all of the grain that went in has to come
back out. Cleanliness of the boiler will have the largest effect on
your fermentation success.
if you intended to distill on the grains, the main question that I
would have a firm understanding of the answer is: 'how am I going to
get the grains back out and then clean the boiler'.

ferment in the still,by dissconecting the copper union on the lid and inserting a air lock=====================================I passed on this query to Ian, and his reply is copied belowMike N--------------------------------------------------------------------------He'll have to scale the recipe up to at least 50 gallons, just running a few inches on the bottom is not a good idea. Also, with a pot still he'll want to strip the batch before he does the final spirit run. A 30L batch of mash yields only 20L of liquid to be distilled, and that 20L only yields about 3.5 or 4L of low wines for the final run. The 3.5 or 4L would definitely be to small in a 100 gallon pot still for doing a spirit run.As for mashing and fermenting in the still boiler, this would work, but he'd have to keep in mind that he would need to aerate the mash before he puts the yeast in, and he will have to separate out the solids before he can strip it. So, he will definitely have to move the mash from the still after the fermentation is finished before he can run it. If he tried to strip the mash with the solids in place with a propane-flame heat source he'd scorch the grain solids on the bottom of the still boiler.RegardsIan
