Ultimate Wine SG Chart: Discover the Perfect Specific Gravity for …
2024年12月29日 · Grape juice transforms into wine through fermentation, a magical process affecting specific gravity (SG). Winemakers must keep track of SG because it directly impacts the quality and characteristics of their vintages.
Fruit Data: Yield, Sugar, Acidity, Tannin @ Improved Winemaking
SG refers to the Specific Gravity of the juice extracted from the fruit. Such juice is as low in non-fermentable suspended solids (SS) as possible. Where there was known to be a high level of non-fermentable SS in the juice, the SG is quoted as x (less than x) where x is the SG value obtained with the SS present.
Checking the Specific Gravity and Racking - Winemaker's Academy
2012年10月29日 · After the primary fermentation has slowed down (after about 7 days) it’s time to check the specific gravity. What this tells us is how the density of the wine compares to that of water. Grape juice is more dense than water. Thus before we fermented the grape juice the specific gravity was over 1.0.
Grape juice density - kg/m 3
Density of Grape juice is 1054 kg/m 3. Volumetric mass density of Grape juice (Food, Beverages, non alcoholic (including soft drinks and juices)) in other popular units: = 1.054 [ kg/L ] or [ g/mL ] or [ g/cm 3 ] or [ t/m 3 ]
Freshly expressed grape juice consists of 70 to 80% water and many dissolved solids. These soluble solids include numerous organic and inorganic compounds. The important group of compounds, from the winemaking point of view, include the following: In grapes, a large portion of the soluble solid is sugars.
What Specific Gravity is in Wine Making! (Get The Research!)
After the first fermentation in your wine has abated, which occurs at about seven days, it’s time you measure/check the specific gravity. This will help you figure out how the density of the must/wine compares to that of the water. Fact: Grape juice is denser than water. Let’s take a look at some numbers.

2024年12月29日 · Specific gravity readings provide invaluable information about the sugar content in your must (unfermented grape juice). If it’s too high you can either dilute it with water or adjust acidity levels according to your desired taste profile.

Brix is defined as the percentage of total solids in solution, in grams of solute per 100 grams of solution and is the most used unit for sugar content in Wine Industry. Specific Gravity is the weight of 1mL of solution divided by the weight of 1mL of distilled water at 20C.
Must Weights - Savvy Wine Studies
2021年3月19日 · Baumé (Bé°) is a hydrometer scale used to measure the specific gravity of liquids. It’s convenient because it gives winemakers an estimate of finished alcohol levels. Both Baumé (Bé°) and Brix (°Bx) scales give us a measure of soluble solids in grape juice. Plato (°P) is a scale that expresses the density as the percentage of sucrose by weight.
Grape juice concentrate is generally at 65 -68 Brix, this being close to the limit of solubility of glucose and fructose in water. There is a misconception amongst some winemakers that 68 Brix concentrate contains 680 g/L sugar. IN FACT, IT CONTAINS 908 g/L! The specific gravity of this concentrate is 1.336 so according to the formula above,
