    Batch Primed for the first time today and forgot to take a fg reading first. How much would 180g in 18l raise the reading by .
    It's a brew ferm grand cru and that's the recommended "sugar 2b

    what was the reading after you put in the sugar? What exactly did you use to prime? EG Table Sugar, Dextrose, DME or?

    Opps. Thought I'd put that in. I used golden syrup and the fg was around 1.015 IIRC. Just curious about the effect as I feel that it'll be tenths of a percent which doesn't matter much in a 7.5% beer

    i m certainly open to correction but if i remember rightly priming generally adds half a percent to your abv ,obviously there are slight variations depending on what you use, how much you use etc.
    take a reading when its carbonated and add that half a percent to get your abv, i think this would work.

    Have a look at the attached there, I have this calculator on the phone for working out how much water or malt extract to add to achieve a desired gravity. I've used this in reverse (kinda) by putting your FG post priming , in as the desired Gravity and guessing the actual FG - If you had used 180g of liquid malt extract then 1.012 would be your FG.

    Problem is I don't think golden syrup has the same fementable attributes as LME so you might need to check that
