Use this oenology calculation to document or plan a defined fermentation, blending, adjustment, stabilization, aging, packaging, sensory, or cellar operation from measured wine parameters.

Bottle volume (L)

Filled wine volume in the package.

Dissolved oxygen (mg/L)

Dissolved oxygen measured at the filler.

Headspace (mL)

Air trapped under the closure.

Add dissolved oxygen at the filler to the headspace contribution for the total package oxygen of a sealed bottle. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

TPO (mg/L)

Total package oxygen expressed per liter of wine.

• Wine chemistry and microbiology depend on temperature, pH, alcohol, sugar, matrix, measurement method, microbial state, legal limits, product formulation, and bench-trial response. Generic doses and thresholds are not production instructions for every wine.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Confirm measurements with calibrated winery methods, run scaled bench trials, record additions and lot volumes, check local regulations and supplier specifications, and obtain professional laboratory advice for faults or stability risks.

• Dissolved Oxygen at Bottling Checker

  Compare the filler dissolved oxygen reading against the cellar's bottling specification.

• Bottle Headspace Oxygen Inventory Calculator

  Calculate the gaseous oxygen inventory in a headspace from its volume, oxygen fraction, and oxygen density; this is not a prediction that all headspace oxygen will dissolve into the wine.

• Bottle Fill Height Check

  Check a measured ullage against the fill height band for the bottle format in millimeters of headspace.
