so ive started my first batch of hard cider, yes im yet another beer guy crossing over in to the cider world. but my question is when i added brown sugar following a recipe it didnt raise my gravity as much as i had hoped it would. my og before adding 2 lbs of brown sugar in to a 5 gallon batch was 1.060 and after was 1.065. ive been thinking about it and i didnt wait for the sugar to dissolve or any thing, i stired it really good but not long enough to fully dissolve. so would undissolved sugars not read correctly on my hydrometer? and if not not any guess on how much it should have raised my og. thank you for reading this mess and any feed back would be great.
