Hope this is not too elementary but I am working on my first batch. Followed the instructions on the fruit wine base lable, yesterday was add yeast, today is stir gentely and repeat daily until SG lowers to 1.040 (four or five days). When I uncoverd the primary fermenter today I observed an off white froth or foam on the top of the contents, is this what I should have seen? Also I just keep reading more and more on the internet then ordering more supplies, do you ever get to the point where you think you have everything you need? My wife is starting to hope so.
