Got a Belgian dubbel on to brew today. Not a style I've gone for before and I used 150g dark Belgian Candi sugar from Maltmiller with a 3kg base of pilsner malt. This was for a 10l batch. Brewday was smooth enough but the colour of the wort was much lighter than I expected. At first I thought perhaps the candi sugar hadn't dissolved but the OG was spot on so it must be something else. Beersmith predicted around 30ebc but if I was guessing I would say it's come out about 15/20 ebc max. The Candi sugar is supposed to be 450 ebc and I've never had any issues with the prediction of ebc on beersmith before. What am I missing? I'm not too concerned as it should still be decent, just not as expected. Thanks!
