my 2 cents worth
...well more like a few bucks worth
I would not give up on Beet Molases based on one or two's comments about it being bad .
I have been making ( or trying to make ) Rum for a few years . Started with pissy brown sugar washes then ventured into sugar + cane molasses blend ( AKA Hook Rum and Pugi styles ) until finally 100% cane molasses .
I have used used various Oak from raw ,toasted , charred , both french and american white ....did I mention Home brew shop Oak chips ?...no...good
I have used Pot stills and Plated stills with a lot of variations of plate numbers and thumpers ....and then there were the cuts...and variations on cuts ...cuts , cuts , cuts ,cuts ,cuts , cuts
I'm not trying to blow my trumpet , just explaining the painful number of variables that can influence a drink
But the Main point I want to make is that most Rum I have made In My Honest Opinion tasted crap
....there has been very few Yummy Rums
And its not just my Rum , I have tasted a lot of other Home made Rum and again there is a huge variation in taste and smell
I have also tasted some absolutely excellent Home made Rums From Salt bush bill , and others on another forum...occasionally I even make one myself that's no half bad
So if I was to try a new Rum wash with something like Beet Molasses I would be foolish after one attempt to say it tastes crap .There are so many variables that can make the difference .
I say "go for it and don't give up"
. Remember , if it ends up tasting bad , stick it through a reflux still and drink it as a light Rum or Neutral ( if you can clean it up enough)
Re evaluate what you did . Try to hone in on why it tastes bad ...or if its better
...change things a bit next time and have another go .
For the record , I have never tipped out a Bad tasting Rum ...Whether mine or someone else's , I know the time and effort that goes into making this stuff .
...at the end of the day , they all work
Incidentally I remember in one of those old Rum making books ( circa 1900 IIRC ) references to making Beet mollases rum and nowhere can I remember it saying it tastes bad .
