O.G when adding more things to mash

[Brew2Be]

Hi there!

My question is: If i make a batch of something, in this case wine, and i do a gravity reading, what should i do in regards of calculating ABV if i add more sugar or some water a week later? Or if i add a starter?

Thanks!

Well, you can just add the ingredients to your OG. Or you can take the SG before you add the sugars and then take the SG after, and the difference would be added to the OG.
