I made a stout up the other week, its about 8% which is where I wanted it, just a fairly simple question. If I wanted a less sweet one, without losing any alcohol content, could I stir in say a few hundred grams of treacle after the initial kilo, adding new yeast with each addition? Would I need any yeast supplement? Would the addition of me stirring it in cause any possible infection, due to too much oxygen? (the latter of which I thought of additional yeast). If it does become infected, should I leave it in primary, taking note of the fact I only have the one, ir bottle it? Would the bottles preserve any imperfections until such a time I drink it, leaving me with food poisoning (or the equivalent)? Am I worrying too much? What if say I wanted a strong stout, alc about 15%. Could I add all the sugar straight off, and not worry, or would it poison the yeast, leaving it useless after about 10%? Also, would it be too sweet to drink, leaving me with a sweet white wine kinda taste? My mixtures are well aerated, usually have a few inches of froth on top, which I then sprinkle the (dry) yeast on top of. Would stirring the yeast through provide any additional benefits?
