Karmijn de Sonnaville is a variety of apple bred by Piet de Sonnaville, working in Wageningen in 1949. It is a cross of Cox's Orange Pippin and Jonathan, and was first grown commercially beginning in 1971. It is high both in sugars (including some sucrose) and acidity. It is a triploid, and hence needs good pollination, and can be difficult to grow. It also suffers from fruit russet, which can be severe. In Manhart's book, “apples for the 21st century”, Karmijn de Sonnaville is tipped as a possible success for the future. Karmijn de Sonnaville is not widely grown in large quantities, but in Ireland, at The Apple Farm, it is grown for fresh sale and juice-making, for which the variety is well suited.
