Hi....from what I've been told Frontenac has very high acid levels if
you dont let them hang long enough......once fully ripe they need
another week or so for the acid to "drop" then the levels are more
acceptable ....that is if you're growning season is long
enough........myself I figure if one is not that concerned about
adding acid reducing additives they may be worth growing....they can't
have acid levels much higher than what I grow here in eastern Canada
now....valiants and minnesota78's......Andy J.,Fredericton
