@veryred Sorry for the late reply; been busy.
Hunter Valley. I love hunter valley and they are famous for their white wines made from the
SEMILLON Grape.
Traditionally semillon has been (and still is) one of the 3 grapes that go into making white bordeaux wines (yes there are white wines from bordeaux).
It is in the Hunter Valley that they are famously made as a 100% wine without other grapes. They are fresh, zippy and lemony when young but they have a very interesting characteristic when they age. They can age marvelously and the best ones can easily go up to 20 years.
At about the 8-10 year mark, the good semillon lose a bit of the lemony-ness and zip but they gain in body, texture and toasted notes which is quite unique as a traditionally they are not fermented and matured in oak barrels; they
naturally become toasty over the years (if you have patience).
For reds, Hunter Syrah (shiraz) has grown in leaps and bounds recently with a more elegant style of shiraz rather than the stereotypically over-ripe aussie fruit.
