Context & source

Source-reported cluster weight for the named grape cultivar in its HortScience register entry. The source may give one value or a literal range, and may state trial location, treatment, tipping, approximation, or a lower-bound qualifier. Preserve the imported string exactly; do not parse a range, turn an approximate value into a point estimate, or imply a species-wide constant.
