Strategies for a Chaptalization Mistake

Balancing Wine’s Structure: Techniques to add and remove tannins
FREETannins 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 ONLYWell, 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
Cures To An Oversulfited Wine

Maturation Intervention
MEMBERS ONLYNo 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.
Properly Adding Copper
FREEAh yes, the classic “I sunk a bunch of pennies in my carboy” tale. Forgetting for a moment that modern pennies contain very little copper, there’s a reason that most winemakers I
Oxygen Ingression
MEMBERS ONLYDon’t worry, it’s happened to the best of us! If you can, check your pH and your VA (volatile acidity) to try to get a handle on whether or not this air intrusion caused any chemistry-altering damage to the wine. What I mean is, sometimes when we have an oxygen incursion it can mean an
Overcompensating With Copper
MEMBERS ONLYAh yes, Monday morning quarterbacking is always tough when it comes to wine. Adding a complex yeast nutrient (a mix of nitrogen, amino acids, and other micronutrients) is something I do with every fermentation. I have the luxury of being able to send my musts and juices to a wine lab to measure their amino

The Tale of the Stuck Fermentations
MEMBERS ONLYA fermentation is “stuck” when it fails to reach the desired conversion level of sugar, usually coming to a halt somewhere below 10 °Brix. It does not refer to a failure to start, which is a different issue. I used to have a lot of stuck fermentations at home but really haven’t had a problem for

Troubleshooting Off-Odor in a Viognier

Knocking Down Rot On Grapes
MEMBERS ONLYThat’s a great question as we approach the harvest season. Though I don’t expect 2019 harvest to be like 2011 or 1998, many of us all over the country, from Oregon to Pennsylvania, will have to deal with some kind of rot or Botrytis close to harvest time. When I’m potentially faced with it, I
Pressure in the Home Vineyard: How to measure and mitigate fungal disease
MEMBERS ONLYAll photos courtesy of Shutterstock.com It is not lost on the well-informed winegrower/winemaker that fungi — ancient, single-cell organisms that have been on this planet hundreds of millions of years longer than humans — are our best friend in the winery and our worst enemy in the vineyard. How is that possible? Yeast are fungi,
Softening The Wine
MEMBERS ONLYBefore I launch into my information about gum arabic and related products, do take a minute to think that gum arabic may not give you the result you’re looking for. Gum arabic can smooth out the perception of tannins in some wines, but I’ve found that sometimes it can make the problem seem worse. If
