ok i am staring a mini vineyard in my back yard....will have 5 rows of 4 vines and i would like 5 different grapes. I have Chadonell and White Niagra right now. Was at Lowes yesterday and the have some pretty healthly 1st year Catawba grapes on sale for $10. Are these grapes any good for wine? (not that White Niagras are the greatest wine grapes)
