Crab · 2 trees planted · confidence low
A small red-fleshed crabapple with deep cranberry skin, dark red flesh and a sharply tangy, mildly astringent juice, used to add acid, color and some structure to blends — small additions push finished cider toward a rosé hue. Trees are small (12-16 ft mature), precocious at 2-4 years, and midseason blooming, so they need another midseason variety as a pollinizer. This is the weakest-documented entry in the set: no WSU, Cornell or other university trial data exists for it.
Disease: Nursery sources claim good general disease resistance and strong cold hardiness, but there is no extension or trial data behind this. Treat scab resistance as unverified in a wet maritime site.
Discrepancies: Absent from the WSU cultivar database (77 cultivars) and from all extension sources — every attribute here rests on nursery and produce-catalog copy, which is the bottom of the preference order. Sources also disagree on tree size: Trees of Antiquity calls it a very small tree at 12-16 ft, while crabapples of this class are commonly vigorous. Recorded vigor as weak per the only source that addresses it, and tannin as medium inferred from described astringency rather than measured. Name is ambiguous (Red Vein vs Redvein) with no accession standard, so the orchard's trees cannot be confirmed against any reference. Confidence held at low-medium for this reason.
