I haven’t measured it before. Guessing around -10,-7C somewhere due to residual heat from our living room and the glasseed balcony being wind resistant.
Apple tree, pear, cherry are all cold resistant but obviously unfit for a grow bag on the balcony. I’ve heard there are are types of grapvine that can do swell in hardiness zone 5ish, not sure which kind yet conflicting info on the webz.

Where I used to live there are some grapevines that give big round passionfruit tasting grapes that resist at least -5°C
