Wine Lab Tools

Simple Calculators to support your daily work:

Brix to Sugar Calculator

Estimate sugar concentration in grams per liter from °Brix.

Enter a Brix value to estimate sugar concentration.
Formula: Sugar (g/L) ≈ Brix × 10
This is a quick estimate for practical winery use. Actual sugar concentration may vary depending on solution density and composition.

TA Conversion Tool

Convert titratable acidity between grams per liter and percent tartaric acid.

Enter a value to convert titratable acidity.
Formulas: % tartaric = g/L ÷ 10   |   g/L tartaric = % × 10
This tool assumes titratable acidity is expressed as tartaric acid equivalent.

SO₂ Adjustment Calculator

Estimate the grams of potassium metabisulfite (KMBS) needed to raise free SO₂ in wine.

mg/L (ppm)
mg/L (ppm)
Liters
Enter your values above to calculate the required KMBS addition.
Formula: grams KMBS = (ΔSO₂ × L) ÷ 570
Assumes potassium metabisulfite (KMBS) is approximately 57% available SO₂. This is a practical estimate for winery use.

SO₂ Stock Standard Calculator

Calculate the grams of sodium metabisulfite (Na₂S₂O₅) needed to prepare an SO₂ standard solution.

mg/L (ppm)
Liters
Enter your values above to calculate the required raw material.
Formula: grams Na₂S₂O₅ = (mg/L × L) ÷ 674
Assumes sodium metabisulfite is used to prepare an SO₂-equivalent standard.

Dilution Calculator

Calculate how much stock solution is needed to prepare a diluted solution.

mL
Enter values to calculate required volumes.
Formula: C₁V₁ = C₂V₂

Required Metabisulfite Calculator

Enter a desired SO₂ amount and calculate how much sodium metabisulfite or potassium metabisulfite is required.

grams SO₂
Enter a desired SO₂ amount to calculate the required raw material.
Factors used: Na₂S₂O₅ = 67.4% SO₂   |   K₂S₂O₅ = 57.6% SO₂
Values shown are theoretical SO₂ equivalents based on formula weight.

DISCLAIMER: These calculators are provided as helpful tools for estimation and general guidance only. While we’ve done our best to keep the math honest, real-world winemaking (and brewing) has a way of keeping things interesting.Astoria-Pacific, Inc. is not responsible for any outcomes resulting from the use of these tools, including—but not limited to—off-spec batches, unexpected results, or a beer that turns out… “experimental.”Always verify critical adjustments with your own methods, instruments, and good judgment. When in doubt, trust your process—and maybe double-check the numbers before adding anything to a 1,000- or 30,000-liter tank.

Laboratory Automation

API Building Main

Automate routine wine analyses with high-throughput systems like the rAPID-T.

API Building Main

The rAPID-T System simplifies wine testing by automating key assays such as Acetic Acid, Glucose + Fructose, L-Malic Acid, NOPA, Ammonia, and Total SO₂.
When paired with the Free Sulfite Sample Prep Station, it enables fast, accurate Free SO₂ analysis—improving lab efficiency and reliability.
