I've made a few batches of great tasting beer, and although I still consider myself a beginner, I've started really experimenting with different sugars, flavours etc. Yesterday, I made an Irish stout with dark malt extract, about 1.1kg combined of treacle and golden syrup, (yes I'm Aussie, therefore use metric) and today I checked on it, its one of my most active brews yet. There's a good ten litres of foam on the top, and it has readily reached the lid, which is the equivalent of 15 litres off the surface of the beer. I was wondering whether I should have used as much of the golden syrup, am worried I won't get the full bittersweet taste I was after, instead it becoming too strong to drink this winter, requiring storage until next.. any advice, apart from leave it and see how it goes?
