Comments
The small berry size of 'Magnolia' relegates it to the juice category. We found it to perform similarly to 'Carlos', with no real advantages over 'Carlos', and it has a wetter stem scar than Magnolia grapes on vine 'Carlos'. Because it is not superior to 'Carlos' we do not recommend planting of 'Magnolia'.
