Hi, Apologies if this has already been asked/answered before - the advert at the top of the page is overlapping the search box meaning that I can't search the forums! Is there a simple way of calculating the final alcohol percentage if I have added water part way through the process? I'm currently making Elderflower wine, and the recipe I was following got me to top up with water after the first racking. I started with an SG of 1.152 (9 litres of water), and yeast added at this point. At the first racking, it was 1.100. 8 litres of water then added, making the SG 1.040. When fermentation fully ceased, and after the next racking, it was at 0.90. I've not the foggiest where to start with this - there'd obviously be some alcohol in there from the first fermentation, but I've then diluted it. This is only the fourth batch of wine that I've made, and the first where I've 'tinkered' with the wine part way through! Many thanks in advance.
