Not sure how you brew but if you use dextrose or table sugar in your brew then substitute at the same ratio.
I have a mate that used to grow and crush his own and had a few of his beers and they have that very distinct molassas like flavour, a bit like the smell around a sugar mill. It wasn't offensive in any way and was a nice addition but it was definitely distinct and you wouldn't want to brew every beer with it- just one now and again fro something different.
