Hi all, I am new to wine making and new to the forum. Currently I am making my first batch. I have a Master Vintner kit and the instructions say during primary fermentation to add yeast nutrient when the SG reaches the range of 1.04 to 1.05. When I used the thief to put some fluid in the test tube it seemed as though there was a lot of gas dissolved in the wine. After placing the hydrometer in the tube the initial reading was about 1.045. But gas appeared to fizzing out of the wine and the hydrometer reading was increasing fairly fast. Should I use the initial reading or wait for the reading to stabilize?
