This is a depressing day for grapes and Cumberland College.

On this day in 1916, the Georgia Tech college football team smashes Cumberland College 222-0. That score still stands as the most lopsided game in college football history…and for Cumberland Collage, the most depressing.

That brings us to our Wine Word of the Day: Crush

Yes, it is a wonderful time of year. It’s football season AND the wine harvest is on! That means we hope our favorite teams crush their opponents, and that our favorite wineries crush our favorite grapes.

Although we’ve all heard the wine term “crush” before, it seems some folks are still a little unclear as to exactly what that means.

Generally, wine makers will refer to late Summer and most of Fall as “Crush Season”. But if you are a grape grower, to you, this is “Harvest Season.” The act of crushing is mainly done with red grapes these days. What happens is the grapes clusters are harvested, then taken to the winery. There they are put into a machine that does two things at once: destemming and crushing. The wine industry, in an attempt to confuse people, though, calls this machine the destemer/crusher.

This efficient, technological wonder quickly removes the grapes from the stems. The grapes then pass through soft rubber rollers that gently break their skins to release the juice into a fermenter. The stems are typically discarded. Yeast is then added to the fermenter where it eats the sugar in the juice and converts it into alcohol. Keep in mind the skins of the grapes are still in the fermenter to give red wine its color because almost all grape juice is clear.

After the yeast converts all the sugar to alcohol, the juice is put into barrels. However, about 20% of the juice is still attached to the skins. Winemakers, being a greedy bunch, will press this juice out of the skins using another machine. That device is known by industry insiders as the “press”. White grapes usually go straight to the press after harvest. Their skins aren’t needed, so the juice is pressed directly into barrels or tanks for fermentation.

In the old days, grapes were crushed by foot. The foot is an excellent crusher because it is heavy enough to break the skins, but soft enough not to break the grape seeds. If you break too many seeds, the wine will be very bitter. Kinda like the rivalry between Georgia Tech and Cumberland College, or Lucy and the Italian woman in the grape vat.

September 20 – “Sugar”

Today’s word puts us in a sticky situation.

On this day in 1969, the Archie’s “Sugar, Sugar” hits #1. Its syrupy-sweet and vapid beat can stick in your head for days and certainly disrupt your sleep.

So let’s not dwell on it and get right to our Wine Word of the Day: Sugar

Without sugar in the grapes, there would be no alcohol in your wine. And what fun would that be?

Yeast is our best friend when it comes to doing the job of converting the sugars into alcohol. They’re pretty good at it, too. When yeast eats sugar it converts about 55% of the sugar into alcohol. The process is called fermentation (but you probably already knew that). So, if a winemaker wants a dry wine to be about 13% alcohol, they will harvest when the grapes ripen to a sugar content of about 24%. That’s a pretty sweet fruit. To put it in perspective, table grapes like Thompson Seedless are picked at 17%
sugar.

If the winemaker wants to make a sweet wine, they have to stop the fermentation before the yeast eats all the sugar. This is usually done with refrigeration. If the winemaker wants to leave 1% residual sugar in the wine, he will chill the wine to almost freezing. This kills the yeast before it can finish eating the sugar. The result is a semi-sweet wine with a slightly lower alcohol level.

If a winemaker wants to make a dessert wine, he’ll pick the grapes when they are much riper, say, 35% sugar or even higher. These are typically known as late harvest wines. Many people blame hangovers on these wines. But my guess is that dessert wines are usually served by overly sweet hosts that insist you have just one more “nightcap” after you have already plenty of wine for the evening. And, I’d agree those headaches can be every bit as bad as the ones the Archie’s could give you!
