Consulting Services

Winemaking. Brewing.
Spirits. Mead.

Four disciplines. One consultant with the scientific background and production experience to work across all of them.

The Approach

Consulting rooted in chemistry and craft

Joe's consulting philosophy is simple: understand the science, respect the craft, and give producers the specific knowledge they need to make better decisions — faster. Every engagement begins with listening, followed by honest, data-driven analysis, and concludes with actionable recommendations you can actually implement.

Consultations are available for acute problems (something went wrong), proactive improvement (how do I make this better), and ongoing production support throughout the season or production cycle.

In the Lab

Every diagnosis
starts with data.

Joe's chemistry background means your production problems are evaluated analytically before any recommendation is made. Whether it is a free SO2 measurement, a pH drift, or a complex fermentation fault, the lab answer comes first.

01
Winemaking

From harvest to bottle

Whether you are trying to correct a problem, optimize a process, or plan your next vintage from scratch, Joe provides the expertise to guide your winemaking at every stage — with a chemist's precision and a winemaker's palate.

02
Beer & Brewing

Science behind every pour

Brewing is chemistry. Joe's scientific background gives him the tools to evaluate your process at a technical level that many brewing consultants cannot match — whether you are scaling up a recipe, diagnosing inconsistency, or launching a new brand.

04
Mead & Specialty Fermentation

Fermentation without boundaries

Meadmaking combines the sensitivities of winemaking with the unpredictability of honey as a fermentable. Joe has worked with mead producers on nutrient management, flavor development, and problem-solving for some of the most challenging fermentations in craft beverage production.

05
Viticulture

Great wine starts in the vineyard

As a faculty member in SRJC's Viticulture program, Joe brings current academic and field-based knowledge to vineyard consulting. His work bridges the gap between the growing season and the cellar — because the decisions made in the vineyard drive the options available at crush.
