P.S. Just another thought. As a comparison, I'd say this wine mostly resembles the Casa lapostolle Cuvee Alexandra Cabernte Sauvignon as well as the Concha Y Toro Marques de Casa Concha Cabernet Sauvignon.
They sell for something like $15 to $22 and do range from about 88 to 91 points regularly. I am not good at assigning points, but the last glass balanced tension with the fruit still very well in evidence and the brambly character gone....yes I would put it in the 90-91 range.
