Cells report odds ratios with delta-method standard errors in parentheses. Significance: ***p < 0.01; **p < 0.05; and *p < 0.10. The East/Other regional dummy is dropped from the ordered-logit model because too few wineries in this group are positioned in the Iconic tier (quasi-separation); the qualitative pattern of the remaining coefficients is unaffected.
