I agree with
@KCCam, that is a LOT of sugar. You'll get a very strong wine and it will likely have residual sugar.
@farmhorse62, it appears you did not record the original specific gravity (OG). If I understand correctly, the readings you posted are after fermentation started. Off hand, if the wine tastes ok at this time, you're probably going to get a successful batch. Jet fuel may be jealous of the potency of your wine, but as long as it tastes good!
Next time, change your procedure:
- Crush the fruit, press out the juice (this assumes you don't want to ferment on the skins).
- Check the SG of the juice. If it's between 1.080 and 1.100, you don't need to add sugar. If you need to add sugar, for 3 gallons of juice? Add a cup, stir well, check SG. Repeat until the SG is where you want it.
- I wouldn't add water -- I see recipes that call for adding water, but that dilutes your juice.
- Fermentation typically takes 5 to 8 days when the temperature is 65 F to 75 F. Once the SG gets below 1.010, you can rack and move to a carboy or other jugs. IF there is activity, leave a few inches of head space so you don't overflow the container.
If you want the wine stronger, add more sugar than I indicated {before fermentation}. If you want to back sweeten (scuppernong tastes stringent when dry, so a bit of sugar changes the taste), ferment it out dry. After the wine clears, add sorbate and sulfite (to prevent a renewed fermentation) and sweeten to taste.
