Palate-friendly hybrid

vignoles

Six Mile Creek is in the town of Ithaca, right on 79.

Six Mile Creek Vignoles 2007
Varietal: Vignoles (also known as Ravat 51)
ABV: designated as “table wine” so between 7-14%
Price Point $9.75
Notes:
Looks: Mild yellow, kind of like a light vegetable oil
Nose: Right away there’s pear and creamy component kind of like baby food (like mashed bananas or something). Perfumey floral aromas are present, too, with touch of sulfur off-aromas* on the back end.
Palate: Fresh acidity with a little sweetness. Very enjoyable, I would drink this a lot, especially for the price.
Rating: 3 corks corkcorkcork


Six Mile Creek is the closest winery to Ithaca, and they have some decent wines. They also have grappa (made from distilled grape skins), limoncello, vodka, and gin, all distilled from grapes. Usually I’m not too big on hybrids, but I really liked this wine.

Science!
I’ll talk about hybrid grapes like Vignoles another time (basically, they’re cold-hardy crosses between European-native {vinifera}, and Native American grapes.)

Hey, dudes, do you smell me?

Now though, I’d like to talk about sulfur. Sometimes called “reduced” aromas or “sulfur off-aromas”, things like rotten egg, garlic, old cabbage, etc., can invade wine under certain conditions. For example, if the fermenting {must} doesn’t have enough nitrogen content, the yeast will metabolize the amino acids cysteine and methionine (the two sulfur containing amino acids) to create other amino acids and nitrogen compunds like nucleic acids. The result of this metabolism is the creation of hydrogen sulfide (rotten eggs, also one of the active gases in flatulence (Ref: Oghe et al., “Effectiveness of devices purported to reduce flatus odor”, American Journal of Gastroenterology, 2005, interesting read actually) and mercaptans (cabbage, onions). The human nose is actually quite sensitive to these compunds, detecting them at around 1 part per billion. This problem can be treated by copper fining, but winemakers have to be careful not to exceed the legal limit of copper. I’ve heard that if you have a pre-1982 copper penny, you can drop it in and remove some of the sulfides, never tried it though. A better way to get rid of sulfur off-aromas, especially hydrogen sulfide, is to aerate the wine, e.g., in a decanter or a pitcher, or heck, even a blender!
Other fun mercaptans include ethyl mercaptan, added to natural gas (which is odorless), so you know when you’re about to blow up. And 2-butenethiol is secreted by skunks. They’re not all bad, though. Grapefruit and passion fruit aromas (3-mercaptohexanol) are also mercaptans. If you’ve got too high a concentration, though, it will smell like B.O.
