Default Chaptalisation and ABV calculation

I tried searching for this as I thought it must have been asked before, but could not find any posts that answered me....

I started my second kit tonight -- a WE Choco-Raspberry Port. This kit has a chaptalisation packet --- so I am wondering how I need to calculate the ABV of my finished wine.

With my first kit, I used the (OG-FG)*131 = %ABV
with the chapt. step, I am adding in more sugar that then gets fermented into Alcohol content -- so this is what I am thinking

OG = original SG
FG = final SG
PG = "Primary" SG (after ferment, before Chaptalisation)
CG = "Chaptalisation" SG (after adding the Chapt. pack before continued fermentation

( (OG-PG)+(CG-FG) ) = %ABV

Do I understand what is going on and have my calculation correct?


What I have made...
