Tannins are a big piece of the large puzzle when balancing many styles of wine. It’s important to understand ways to increase or decrease their presence when that balance leans too heavily in one direction or the other.

Troubleshooting Malolactic Fermentation

MEMBERS ONLY

Well, it’s tough to say what would make one cloudy and the other clear, except for the fact that they may not have been identical coming from your fermenters. If you did blend/homogenize after pressing, then it’s possible you’re seeing the cloudy wine (pH 3.77) going through the MLF (malolactic fermentation) a little more quickly

Maturation Intervention

MEMBERS ONLY

No matter how much attention we give a wine, sometimes it will disappoint when tasted for the first time during aging. It may not be faulted, just lacking a desired characteristic. That’s when it is time to intervene. Qualities like flavor, aroma, body, color, or even tannins can all be improved with a little help.
