I'm new to making wine I have 6 gal of pinot grigio frementing and 6 gal of lambrusco fermenting I want the lambrusco to be sweet we have been reading on the internet and asking friends when to put the lambrusco in a carboy. Is there a apecific sg reading we can use to know if we are ready to move to the carboy. Maybe a dumb question but just don't really know much about it
