Sorry I'm late in replying:
Adding wine to the sauce is strictly optional. You can add small amounts of sugar to offset the somewhat bitter taste of the sauce--if it tastes bitter to you. If you used too much sugar, you can add a little garlic powder.
Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
