42227Re: beano in the mash
- Apr 4, 2012To be honest, I don't see what the fixation is with potatoes. Maybe it's just popular belief? They are just a source of starch. So is flour, and any number of grains. Which were all used to make vodka in centuries gone by. Potatoes were only used as a last resort when the others were not available, or countries/regions couldn't grow grain.
Same as potato starch was used to make bread when grain crops failed. Bit of trivia for you there (longtime baker here before I was a distiller). :)
No matter the starch source, you still have to convert it to sugars. Then those sugars have to be converted to the simple sugar glucose before yeast can use them at all.
Methinks the simplest no-fuss solution is to start with a sugar source in the first place! By all means, play with starches later if you've a mind to. BUT, only when you understand what the hell it's all about and what you can expect (low yields & a lot of work & failures for example).
Think about this...commercial spirits producers would use sugar sources in a heartbeat, if not for laws preventing them.
