Interesting. I do not know this person, and have zero knowledge of her blog/Web site, but expect to see more of the same, in the future.
If the allegations of "play for pay" are true, it should bring down the site, and cast a very bad light on the reviews.
Wineglas1 mentions the Santa Margherita PG, but I have no knowledge of that review. Still, while the producers/importers claim that it is the "most popular PG in the world," I would postulate that it is only because of a giant advertising budget. I have never been even moderately impressed by any vintage of that wine, and see it on many wine lists, ranging from US $75 to $150 in price. I would not pay US $10 for a bottle, but that might just be me.
