Yes, you can substitute KOH, potassium hydroxide, (potash lye)(NOT
regular sodium lye) which should be locally available as generic
brand liquid drain cleaner. Please be careful with this stuff. I
don't know the exact proportions, (a teaspoon per 15L?? depending on
strength) but it will be similar, probably less??? Check the
ingredients, there should be no sodium hydroxide and it should be
nearly clear. For experimenting only, use lab grade KOH if you are
going to drink it. Remember to adjust the final Ph to about 6.0 with
citric acid before pitching the yeast. [This is a VERY strong base
and will soapify your skin on contact.] I have also used potassium
vitamin supplements but not exclusively and the amount required is so
great that it won't be inexpensive (they usually come in 99mg pills)
for large batches. Yeast needs for K are on the order of 4500mg per
15 liter, that's a lot and is equivalent of one cup normal molasses
or 1/2 half cup blackstrap molasses. Molasses is loaded with K.
I must warn you that the acid should be added to the sugar solution
first and then the potassium. (especially if you already added the
DAP first by mistake). You can make small adjustments either way when
the PH is closer to 6PH. Kind of a catch 22 I know.
I'm sure I will be chastised for suggesting drain cleaner. But it is
a convenient economical source of K for testing purposes only cause
we don't know what else may be in it.
