OK, so it was late in the day, a couple of hours before closing, and the tasting room was packed, but we'd just come from wine-tasting at Chateau Grand Traverse down the road and Chateau Chantal suffered from the comparison. Yes, the views of Grand Traverse Bay are, well, grand (their location straddles the spine of the Old Mission Peninsula so there are magnificent views of both West and East Traverse Bay), but the wine quality was decidedly mixed despite the clever names they have for their blends. Some of the whites, and especially their sparkling wine was quite good and we bought a handful of bottles, but the reds were not of the same quality and one was completely undrinkable as in spit it out after one taste undrinkable. Our server seemed intent on getting us served whatever we chose from the tasting list without actually having to engage in conversation or provide any advice, recommendations, or oenological tidbits about their wines. The topper came when she announced that they had run out of one of our choices, which of course can happen, but she didn't say it like they had completely sold out of the vintage; it was more like they had finished their quota for the day, which struck us as odd.
Bottom line: Chateau Chantal is a very scenic spot to visit and enjoy the views from their patio with a glass of wine, provided you don't have very high expectations about the wine or the service.
