Either will be fine. I would make a dark version of Golden syrup by just cooking it a bit longer, because it is quite fun to make. As Nicks90 points out there will be some differences between the approaches, but perhaps not much.Planning on brewing a dubbel tomorrow, recipe is looking like
Pilsner
Munich
Belgian caramunich
Special B
Noble hops
Yeast wlp530
I was planning on making some candi sugar but could I achieve the same by using dark brown sugar
