Maintaining wine balance in a changing climate Climate change is reshaping the wine industry. In many wine regions, each year seems to set new records for the hottest or driest growing season, followed by the earliest harvest dates yet. Such accelerated ripening is disrupting grape physiology; phenolic and aromatic development fall out of sync, sugar levels soar, and acidity drops away (1). So how can we adapt and build a more resilient wine sector? The answer to this question is multifaceted. In the vineyards, grape growers are rethinking their management practices, adjusting canopy architecture, introducing shading or optimising irrigation (1,2). Some are reaching for higher altitudes or moving further from the equator in search of cooler conditions (1). Others are trialling alternative heat- and drought-tolerant varieties, from long-forgotten cultivars to newly bred plant material. In the cellars, winemakers may turn to pragmatic solutions such as dilution or blending strategi

The nutritional health of yeast can determine the success – or failure - of the resulting wine. To get the most out of your yeast, a high-quality nutrient product is essential. “High quality micronutrients are essential to the healthy development of the yeast and a robust fermentation,” emphasizes Bill Merz, Gusmer Enterprises Inc’s Director of West Coast Beverage Sales and a winemaker himself. “The solubility of those nutrients is also key to yeast cell access. That’s exactly the kind of scientific research Gusmer has done and the superior products it provides.” Gusmer Enterprises, Inc., a leading manufacturer and supplier of fermentation and filtration products for the beverage, food and pharmaceutical industries since 1924, specializes in the distribution of yeast nutrition developed to ensure healthy, vigorous and clean wine batch fermentation, vintage after vintage.

Mastering Yeast Nutrition  How to Make a Fermentation Nutrition Plan Proper yeast nutrition during fermentation is key to preventing sluggish/stuck fermentations, preventing off-odors, and maximizing aroma. Scott Laboratories has always recommended making three nutrient additions at specific time points and our fermentation nutrition planner helps determine the right nutrient and dosage for each stage. READ GUIDE When to add Nutrients and Why Yeast Rehydration This nutrient addition helps get yeast into "first gear," supplying necessary vitamins and minerals required to adapt to the new environment and begin growth.  2-3°Brix Drop This nutrient addition "steps on the gas pedal." It helps yeast multiply during their growth phase and reach the maximum cell count that will finish fermentation.  1/3 Sugar Depletion At this stage, yeast have reached their maximum cell count. This nutrient "tops up the gas tank" and helps yeast sustain and com

The 2024 wine grape harvest began on time in August, with Napa and Dry Creek Valleys starting in the first week and Livermore's white grape harvest beginning mid-month, two weeks earlier than last year. Other regions have also reported their season starts as the weather shifts from cool to hot, putting vineyard managers in a race against the clock to avoid sunburn damage. “With the California harvest well into picking what seems to be a beautiful harvest year, wineries are deeply into harvest preparation,” notes Eglantine Chauffour, the Director of Enology at Bucher Vaslin North America (B.V.N.A.). “By now, I’ve usually started hearing about specific challenges from our winemaker customers, but there have not been many this year beyond a few cases of sunburn. The harvest looks great, and when the vintage is perfect, as it's looking so far, we recommend a few things to optimize it.” A good time to think about replacing sulfur A successful vintage i
