Abstract
Until recently, there has been little information on the chemistry of hard cider derived from fruit sourced in eastern Washington. Only a few studies have been published concerning tannin tests for cider apple juices or hard ciders within the northwestern United States. Our current study examines apple fruit chemistry, including tannin assays, in which several common apple varieties were analyzed. These include dessert apples, three English apple varieties, and an �F1-hybrid crab� blend. Two trials were conducted in our study using apple varieties grown on an organic, low-density orchard and apple varieties grown on a high-density, intensively managed, conventional orchard. In both trials, at harvest, individual juice extracts as well as blended ciders were analyzed for percent titratable acidity (TA), percent sucrose (Brix), and percent procyanidins (tannin levels). The organic trial showed �Golden Russet� having the highest percent TA and Brix in juice. �Major� had the highest juice tannin level. The �Improved Red McIntosh�-�Golden Russet� cider blend displayed a high percent TA during bottle aging. However, �Improved Red McIntosh�-�Dabinette� cider had the highest tannin level during aging. The conventional trial revealed the �F1-hybrid crab� apple had the highest percent TA as well as the highest tannin level. The �Golden Delicious�-�F1-hybrid crab� cider blend maintained the highest percent TA during bottle aging. The tannin level was similar during aging between �Golden Delicious�-�F1-hybrid crab� and �Ok Red McIntosh�-�Dabinette� at one and six months of age. The most significant result in this study was that conventionally grown �Ok Red McIntosh�-�Dabinette� had higher tannin levels at both one and six months versus a similar varietal blend grown organically.
