Acids to help the yeast

Post by W.S.C.beachman »

Their was a section I was reading about different acids to help to yeast convert sugars. I was wondering in regards to rum. What could I use to help my yeast convert more of the unfermentables to fermentables. If this is even possible. For instance my SG=1.14 then FG=1.08. I would really like to get the FG down abit. Is there any thing I can use? Phosphoric acid maybe??

Hi Beach,
I believe this to be a worthy experiment for the sake of understanding how unfermentables impact the flavor of our rums. But it is the unfermentables that give us the familiar rum notes/flavor.

Are you hoping to aquire more yeild? Will using a sourse of cane that has fewer umfermentables on a ppm basis be of any assistance?

as LWTCS explains what does not ferment becomes flavor,molasses has caramelized sugars
that does not ferment,to change that you need enzymes not acids,Beno is one.

Oh ok,
Yah I was just thinking that my FG should be lower but it never is and I know it has to do with the unfermentables. I just did not understand that those unfermentables is what gives rum its flavor. I should be happy then that I have flavorful molasses. Ill just add more sugar I guess. Thanks for the tip Dnder.

I have no idea what ABV of wash your shooting for,but more sugar you use the less flavor you have as sugar has little flavor,that goes for all recipes not just rum.its all over net /news,sugar is empty
calories,,,,,in the case of a wash/mash its empty alcohol.

Yeah,,, . 8 or 10% is just fine really.

If you are trying to enhance yeild or more specifically production volumes,,,,just get your self another fermenter or two going..

And so far it has been my experience that,,,,(if you can't get to the stilling cuz life gets in the way),,,,,,aged rum washes/beers are pretty dern good....Takes more than a single run to get it past that weirdness.... but two runs or more and it's really good stuff (so far).

I'm going for a 10% wash. I got it down now how much sugar I need to use. All my other washes(UJSSM,Gerber) would start at 1.08...ish, but would finish at 1.0 or less and that is why I thought some thing was wrong. :) Its all good though!!! To day I will hopefully do a cleaning run for my last batch and tomorrow do my next run. I'm doing one 5 gallon pail at 1 gallon per wash. So I get (5) 5 gallon washes out of it. Then rerun every thing I have collected about 3+ gallons. I collect down to 10% to make sure I get the rum oils like Pugi does. Ill post up to let every one know how it goes for the finish run!!
