Checking Those Sulfurs

Posted on

Sulfur Dioxide is a chemical compound with the formula SO2 and is responsible for the wording on wine labels “contains sulfites”.

One of the most important things to do in the wine making process is to make sure the sulfur is at the appropriate level in the wine. There are a few ways of checking this and I use the A/O method. I adjust my SO2 levels depending on the pH level in the wine. The test only takes 10 minutes per wine.

Here are a couple of reasons to add sulfur to wine:

First, it is a microbial agent which helps curtail unwanted bacteria growth. Second, it helps keeps the wine fresh and protects it from browning. We don’t want the sulfur levels too high though. That’s when you smell that burnt match smell. So it’s important to keep good notes and write down everything you do in your wine makers notebook.

Traveling From Tank to Stainless Barrel

Posted on

I hope you had a wonderful Labor Day weekend…it has been a great start to the 2012 Passaggio Wines…

I took the 2012 Chardonnay and Pinot Grigio off of cold settling and racked them to stainless barrels and tank.  Tasting the juice before fermentation…what a great day!  This is the beginning….this is it – gotta get this right!!!  What’s the pH…?  What’s the TA…? What’s the ML…?  What’s the YAN…? What’s the Brix…?  Whew!!! – here we go…yeast and nutrient are lined up and ready for the next step.  Stay tuned for more…
