Our Services

CUSTOM CRUSH

We offer a home for your wine. Custom Crush is the epitome of fostering a community in the winemaking world. A Custom Crush arrangement is where one leases space, equipment, and provides labor for other winemakers. Over the years, we have outfitted our Sonoma County winery with a wide variety of custom and specialized winemaking equipment and infrastructure. We are pleased to offer a limited amount of our space for other winemakers to craft their wine.

This Custom Crush environment not only offers a place for others to make wine, but also fosters a fun environment and winemaking community for everyone involved. We designed a home for us to make, analyze, and bottle wine—and extend this to the industry we love.

BOTTLING

Designed and operated by winemakers. Winemaking is about details, and bottling is the culmination of months or years of work in grape growing and winemaking. When it comes to this critical step, we want to be in complete control of the final process. We designed our Gravity Mobile Bottling line to meet our high standards as winemakers, and are pleased to offer it to our in-house and offsite customers.

Contact us to learn more about our bottling line and discuss bottling dates. We’ll be happy to share our approach to bottling.

LABORATORIES

Be close to your analysis. We believe in a total understanding of the winemaking process. This means offering a full range of analysis for our customers that make wine with us, as well as other wineries just seeking analysis. We provide quick turnaround on needed analysis to assist with winery decision-making. Operating a high-tech laboratory also means working alongside skilled enologists that can interpret data and offer suggestions based on results.

CONSULTING

Winemaking requires skillful interpretation of a vineyard site into the vision of where you want to go.

Our core winemaking philosophy is that the best wine is made at the intersection between careful monitoring and minimal intervention, favoring informed, early decision-making. Gravity Consulting consists of an experienced winemaking and management team that can provide comprehensive industry expertise. Many times over, Gravity has produced wines of international acclaim. Our winemaking is complemented by vineyard and marketing expertise to make a strong partner for your industry needs.

Philosophy

Wine has a way of bringing people together. We are a team, brought together while pursuing the craft and study of winemaking. Yes, we are a Sonoma County-based custom crush facility. We provide fermentation and processing, barrel aging, a full array of analysis, consultation, and in-house bottling.

But at our core, we are a thoughtful, experienced team of winemakers driven to understand everything about wine and the methods to craft it.

Our Facility

Our facility and every single piece of equipment here are very special to us.

Wine production spaces are complete with a sorting table and delicate de-stemmer, tank or basket press options, open and closed top tanks with hot and cold glycol, gentle Waukesha pumps, Blue Line winery hoses, Bulldog Pups, and much, much more.

Our laboratory is equipped with a broad selection of fine-tuned and precise equipment: spectrophotometer, Anton Paar Alcolyzer, densitometers, autotitrator, centrifuge, turbidimeter, carbodoseur, and more.

Then to our bottling line. The term well-oiled machine never applies so much as here. A DS-12 by US Bottlers, filler & valves by 4-D Machine, cork, screw cap and foils all applied with Bertolaso’s wonderful range of machinery, Impresstik for labels—all work together to offer a finished package.

Enology

Winemaking is often said to be an art. True. But modern wine quality is high because of science, and the studious approach our industry has taken to understanding soil, grapevines, farming, weather, oak barrels, microbiology, wine, and sensory chemistry, among other fields.

These are the areas of focus we love.
