I brewed a belgien white not long ago and realized when I took a hydro I was really low on my goal OG. I realized my mistake right away. The recipe called for only a 30 min boil and I still used 6 gallons of water. When I racked it to the secondary I took a second hydro and emptied the sample in a glass to taste. It was very thin for the lack of a better word and that doesn't tickle my fancy in the slightest bit. I have some malto dextrin but is it to late to use? I have never used it before and I'm not sure if I can use it at bottling or it should have been done at the boil. I have no idea how much to use either...
