Venture a Venturi
Another technique to expose fermenting wine to oxygen is with the above process and device. A Venturi tube, in a wine cellar, serves the purpose of suctioning air into a line to expose the traveling wine to oxygen. After draining a tank of its juice, this Venturi tube is connected to a hose at the bottom. The juice is then fed back to the top where a sprinkler distributes it over the fruit. A very interesting relationship wine has with oxygen. Dependent on it for its young life, but in bottle or barrel it needs very little. Then at the time of consumption, it relies on the exchange again.
Enough about technique. This is hard work! My biceps are growing by the minute, and I'm constantly amazed at how much there is to do in what's considered a medium-sized facility. Even on a slow day we can put in nine hours, and the evening crew still needs to repeat every action from the day.
I'm ready to do some tasting.
