Chardonnay anyone? At this point the primary fermentation is done and the unfinished wine is transferred from the primary fermenting tank to the carboy (that’s a fun word isn’t it? It’s just a big jug). I first tested the specific gravity with my hydrometer. It’s supposed to read less than 1.010 before you can start the next phase. My sample read about 1.000 so it was fine. Specific gravity is a measure of the density of a liquid. The more alcohol, the lower the reading, so you can tell about the progress of the fermentation by the specific gravity. End of science lesson. You can read more about the hydrometer by clicking the link at the bottom of this post.
This step is simple, you just transfer the wanna-be wine from one container to the next, leaving behind the heavy sludge at the bottom of the primary fermenting tank. This is made up of dead yeast cells and the oak wood chips that you put in during the primary fermentation.
You don’t need to add any chemicals or anything at this point. I put an airlock in the top and let it sit at around 72 degrees Fahrenheit for two weeks. Yawn, boring. The next steps get a little more exciting.
