How it presents

WSU cider cultivar trials, Washington · 2002–2017 means

tannin0.1%under 0.2% → not bitter
acid0.64%over 0.45% → sharp
pH 3.46 · SG 1.061 · 14.6 °Bx

Computes as sharp. The analytical method is not stated, so it is not certain the 0.2% permanganate line is the right comparison.

Multi-year means across 2002-2017. Replicate counts and per-season spread are not published, and the trial ground is not the Olympic rain shadow. Analytical method for tannin is not stated, so it is not known whether the 0.2% permanganate threshold is the right one to compare against.

The legendary apple of Newark cider, described by William Coxe as the most celebrated of the cider apples of Newark in New Jersey, and traditionally blended with Campfield and Granniwinkle. Believed extinct until rediscovered at an old Livingston, NJ cider mill in 1976, it is now central to the American heritage-cider revival. Cidermakers use it for an exceptionally dark, rich cider with heavy mouthfeel, and its disease resistance makes it one of the safer heritage picks for the Olympic Peninsula.

Disease: Reported good resistance to fireblight, apple scab, cedar-apple rust and powdery mildew - an unusually clean tree, which matters on wet maritime sites. Upright, tip-bearing habit, so avoid heavy heading cuts. Excellent juice yield at 221 mL/lb.

Discrepancies: Class: nursery catalogs (Albemarle, Raintree) label it bittersweet, but WSU measured tannin 0.10% / acid 0.64% and classes it Sharp - recommended SH per WSU. Acid: WSU 0.64% vs MSU Montana 1.26% - recommended medium per WSU as climate-local. Biennial tendency was unknown from nursery sources; WSU records semi-alternate bearing - recommended moderate. Ploidy remains unresolved across every source checked.
