Why Yeast-Based Nutrients are Better than DAP: Organic vs. Inorganic Nitrogen
Why Yeast-Based Nutrients are Better than DAP: Organic vs. Inorganic Nitrogen
Learn why organic yeast nutrition is an important part of wine quality wine production and helps to ensure reliable fermentation.
What's the Difference?
Diammonium Phosphate (DAP)
Inorganic Nitrogen
Inorganic nitrogen is supplied as ammonia (NH3). The most common winemaking source is diammonium phosphate (DAP), which can be found as a standalone nutrient or can be part of a blended nutrient (DAP with inactivated yeast).
Yeast-Based Nutrients
Organic Nitrogen
Organic nitrogen is supplied as amino acids. Common winemaking sources are nutrients derived from autolyzed yeast. These nutrients supply up to 19 different amino acids as well as naturally occuring vitamins and minerals from yeast.
Why Choose Yeast-Based Nutrients
Although yeast like DAP, it is akin to junk food. Yeast use it quickly and have a metabolic response much like a "sugar rush." Yeast based nutrients are more like a balanced meal, providing sustained nutrition over a longer period of time.
Reliable Fermentation
Yeast-based nutrients help avoid the "DAP crash" meaning fewer temperature spikes, a more even fermentation curve, and a quicker finish to fermentation.
Better Aromatics
Yeast-based nutrients better support the production of aromatic compounds. They also help avoid yeast stress induced by the "DAP crash" that can lead to the production of off-odors (H2S and VA).
Healthier Yeast
Research has shown that yeast-based nutrients lead to healthier yeast that exhibit fewer stress markers. Additionally, the healthier the alcoholic fermentation, the healthier the malolactic fermentation.

About
Scott Laboratories Inc. (USA) and Scott Laboratories Ltd. (Canada) are privately held companies specializing in value-added products and services for the North American wine, craft brewing, and distilled spirits industries.
Our predecessor firm (the Berkeley Yeast Laboratory) was founded in the weeks prior to the end of Prohibition in 1933. Our vision is to provide the best customer service to the specialty beverage community. Our mission is to advance the long-term success of the specialty beverage community by providing best-in-class products and services. We believe in education, honesty, and doing the right thing.
Our first products were lab services and yeast. In the years that followed the needs of our industry customers led us first to cellar supplies, then to packaging and finally into processing and bottling equipment. It has been a 80+ year evolution driven by the concept of adding value.
Our current product portfolios include some of the most famous names in the wine, craft brewing, and spirits industries. In some cases, we have our own proprietary products (such as ScottPlus Dry-Steam Natural Cork and ScottCart filters) while in other cases we work with the industry's leading vendors and suppliers. You can check out virtually all of our offerings on our website at www.scottlab.com.
As of 2020, our companies have 90 employees. Our headquarters are in Petaluma, California and Pickering, Ontario. In addition, Scott Laboratories USA has locations in Healdsburg (Sonoma County) and Paso Robles.
