Garage Enologists of Sonoma County

Sonoma County, California

GENCO was formed to provide a forum for the exchange of ideas and  information, and to promote viticulture and production of quality wine within the membership. We share information on experiences, successes, failures, and pitfalls in making wine and conduct tastings of member wines for evaluation and enjoyment.

At each meeting we explore a subject of particular interest to our members regarding home winemaking or grape growing. We have an open discussion at some meetings and at others we have a knowledgeable guest speaker. We share in the purchase of winemaking supplies (bottles, corks, carboys, supplies, etc.) to obtain larger lots for better pricing.

GENCO meets once a month in or near Healdsburg. The group shares ideas, problems, and wine, and is not only informative, but fun. We have beginner and experienced winemakers. If you are interested in joining or would like more information about GENCO, please contact us at

Speaker: Bruce Hagen

Topic: Troubleshooting Fermentations

Harvest is happening! By the time we meet in September, many of us will be in the thick of it, picking grapes, crushing, pressing, managing fermentations, or even pressing finished wine. 

So, it may be of value to review standard winemaking practices, step-by-step, and look at critical stages, where mistakes are commonly made. There are a number of experienced winemakers in our group who have made wine for years and dealt with these thorny issues, so this open discussion will be an opportunity to share what you’ve learned, talk about what you’re fermenting, quality of the grapes in terms of ripeness and acidity, and how things are going. You could also offer your thoughts about the harvest, the yeast(s) you used, etc. If you’re having problems such as a sluggish or stuck fermentation, or reduction (stinky sulfides) you should be able to get some sound advice. If you just want to know what to do next, here’s your opportunity to get an answer. Also, if you’re still in the market for grapes, maybe someone there will give you a promising tip. 

I’ll be leading the discussion, but will be relying on the experienced members to provide their thoughts, comments, suggestion views, and advice. Afterward, we’ll sample some wines outside. It if you got medals from the competition, or have a wine that punches above its ‘weight class’, bring ‘em’ to share with the others.

We’ll provide the appetizer

In the absence of Mary Lou Marek,  Joan Griffin will officiate the meeting.
