Micio: For a FUN experiment, run your REFLUX still twice with the
same amount and type of wash. One run with the column insulated,
one run without. Adjust the reflux for the same product collection
rate for both runs (maybe 200 ml/hr?) Cut a sample of each to 40%
abv and conduct a taste test.
I've done this multiple times. I'm convinced that an insulated
column gives me a better tasting product at a given collection
rate. I don't know why - and I don't care why, but Harry's
explaination sounds right. Now, maybe at lower power settings
column insulation might not matter.
But lower power settings reduces the collection rate AND the vapour
speed. And I'm convinced of an optimum vapour speed - above which
or below which the product quality suffers. MN has shared his
thoughts on this - and again I've conducted a number of experiments
by making runs at different power settings. For MY still and MY
taste buds, I've found a power input and reflux rate combo that I'm
