Fermentations!

September 20, 2012

Several exciting things are happening now in the cellar. For one, we have inoculated the 2012 Belli Chardonnay with yeast and put it down to barrel to ferment.

Fermenting Chardonnay in barrels gives the wine much greater body and depth, as well as adding nuances of butterscotch and toast, which are derived from contact with the oak itself.

The little devices sticking out of the tops of the barrels are ‘fermentation bungs’. These allow carbon dioxide, a by-product of the alcoholic fermentation, to leave the barrel while preventing air from getting in.

One of the little pleasures of making Chardonnay this way is getting to hear the little ‘blip blip blip’ of gas escaping out through the fermentation bungs. It’s always nice to hear them going in the mornings, it’s a sign that the fermentation is healthy and strong!

Additionally, we have ended the cold-soak on the Monte Rosso Zinfandel, and inoculated it with yeast as well.

To inoculate the crushed grapes, or ‘must’, we add a little bit of juice and a little bit of hot water to a bucket. We then add the freeze-dried yeast culture to the bucket and gently mix it until it has a smooth consistency. Almost immediately, the yeast wake up and begin to ferment, forming the cake of foam you can see in this picture. Once the yeast are rehydrated and happy, we pitch them over the top of the tank and let them go to work!

We estimate that this wine will have just around 15% alcohol when it’s done, so we chose a strong fermenting yeast that can handle alcohol in that range known as K1. This yeast is known for its’ clean character, and for its’ ability to suppress wild yeasts that can cause off-characters during fermentation.

Everything is looking great so far, and we’ve only just begun! Be sure to check back to see how we’re doing!
