just finished our first run at growing fruit in the bottle. after heavy winds this year, we have one apple and one pear. they are still on the tree and ready for picking. I need to wash fruit and bottle with k-meta im sure, but what needs to be added to preserve for years to come without rotting, or re-fermenting and blowing the cork. I have a previous pear wine that I cranked up to 17 % . usually my pear and apple wines are 8 to 12 % depending on year.
