Tell us a bit more bout your surup. Where'd ya git it?

"Has it been pasturized or does it contain any asorbic acid or the like?

Did he send you enough to run multiple batches and therefore enough to collect and/or age some dunder?

I recon a gallon of surup per 20 liter total volume. I'd run first batch with out any nutes and a good bit of yeast (sept for a squeeze of a lemon) to see how well she ferments. You could add a bit of tomatoe paste as yeast like nitrogen.

I run panela (condensed cane juice) and don't really need anything added. She don't go crazy but it is good and steady.

Save your dunder and add back to the next wash. I use about 25% dunder and never have any ph issues.

Gets a very nice floral nose on the 3rd or 4th generation IMO."

"Hi Potszer.
Ok so I'll preface my thoughts with the fact that I have not been able to run a rum batch with any thing other than panela. Molassas is too spendy. That in conjunction with the fact that I am committed to my recipe has kept me glued to staying with this cycle. I want to dial this thing in and get it as good as it gets. I have only run rum ( prolly rhum agricole) for the last year. And my still is specifically built to accomodate this kind of,,,,,,,,,,,,,,,,,,,obsessive behavior.

I do not use a measuring tool to figger exactly what the starting SG should be. I recon I should. Everything is by taste. A mentor has helped me figger that 10lbs of panela can offer the same SG as 8 lbs of table sugar. Could be wrong,,,could be right. Don't care as my still fixes everything just so. And low abv washes make for really nice ferments and really clean runs.

Lots of nutrients in the cane juice. Not sure about your ""syrup"".

Put together the first wash according to what I have mentioned and let it ferment. 4 oz of yeast. I know its alot of yeast, but it will help power through the ferment.
I would recommend that you do get a measuring tool and and try to dial your wash in at 8% to 10% abv. I taste mine (and spit) and am looking for a drywine kind of mouthy feel. Don't swallow any aged dunder wash!!!
Next use 25% of the total volume from your dunder (spent wash) for the next ferment.

So thats 25% dunder
gallon of syrup
4 oz fleischmans dry active yeast ( can use a good ale yeast when you get her dialed in better).
for a total volume of 20 liters.

If your tring to get a faster ferment you can use more nutes or try a yeast starter.
I personally do not care bout speed as my drinkin stock is perty good and plentyful.

What kind of still do you have as the stilling process can help a bunch with rums.

Great thing about rums is that there is plenty of room for your interpretation.

Sorry for sounding so scatter'd but i get excited bout rum."

"Some gents don't like to use distilled water as all minerals and such that can be benificial to the yeast are removed.

You have to be mindful of the clorhine in tap water. Boil first or set out a bucket full for a week (or so).

Depending on the pollution in your area, there is anecdotal evidence that suggests snow and rain water can be benificial for a ferment.

I use water from my well that's put through my household filtration system."
