Due to requests from several of our clients, Osorno stocks a number of chemicals used in wine production in our warehouse. Making good wine requires a lot of patience and knowledge. The additives listed below help balance taste, regulate alcohol content, clarify, and preserve wine.
Calcium Lactate: Widely used in food processing, calcium lactate removes harmful concentrations of oxalic acid, which is particularly important when processing fruit such as rhubarb. Calcium lactate is a powder sold in Osorno Store in 500 g jars.
Citric Acid: Naturally present in most fruits (especially lemons and raspberries), citric acid is comparatively inexpensive. However, it can impart a pronounced sharp acidic taste. For this reason, tartaric acid is often preferred. Citric acid is a fine crystalline powder sold in Osorno Store in 1 kg jars.
Fructose: A natural sugar with a sweetness factor of 1.2, fructose ferments less easily than glucose, and for this reason, is preferred for raising residual sweetness. Fructose is a fine crystalline powder, sold by Osorno in 1 kg jars.
Fumaric Acid: Fumaric acid provides a fruity-acidic taste, and is best used in combination with tartaric acid. Fumaric acid is a fine crystalline powder, sold by Osorno in 1 kg jars.
Glucose: A natural sugar with a sweetness factor of 0.6, glucose ferments very easily, and therefore should be available to yeast in a sufficient quantity at the beginning of the fermentation process. Gluscose is a fine crystalline powder, sold in Osorno Store in 700 g jars.
Sulfur Dioxide: When sodium metabisulfite or sodium hydrogensulfite are added to wine as a "stabilizer", sulfur dioxide is produced. Our product replaces the commonly used Campden tablets. The sulfur dioxide generating solution is sold in Osorno Store in 1 litre bottles, of which 1 ml is used for 1 litre wine, producing 50 mg/l sulfur dioxide.
Tartaric Acid: A natural fruit acid with a clear and neutral fruit acid taste, tartaric acid is the dominant acid in grapes. For this reason, it should also be the preferred acid in making fruit wine. Tartaric acid sold in Osorno Store originates from Italian wine, and is sold as a crystalline product in 1 kg jars.
Yeast Nutrient: Osorno's Composite Yeast Nutrient is a blend of several food-grade substances for optimal yeast development. Our product does not contain potentially harmful urea often found in other yeast nutrients. Osorno's Composite Yeast Nutrient is a powder, sold in Osorno Store in 50 g jars.
