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

Bore diameter (mm)

Inside diameter of the finished neck bore.

Cork diameter (mm)

Diameter of the cork to be inserted.

Maximum compression (%)

Largest acceptable diametral compression.

Minimum compression (%)

Smallest acceptable diametral compression.

Calculate diametral cork compression in a bottle bore and compare it with caller-supplied minimum and maximum limits from the closure and bottle specifications. 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]

Compression (%)

Radial compression the cork undergoes on insertion.

Fits bore

Whether compression sits inside the supplied limits.

• 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.

• Charcoal Color Fix Dose Calculator

  Convert a selected activated-charcoal treatment rate into total mass and compare it with a caller-supplied product, trial, or regulatory limit.

• Fructose-Glucose Ratio Checker

  Calculate the fructose-to-glucose ratio and compare it with caller-selected watch and fructose-dominant thresholds; the ratio alone does not diagnose a stuck fermentation.

• Lightstrike Risk UV Exposure Checker

  Convert exposure duration and measured bottle transmission into equivalent unfiltered light-hours, then compare that value with caller-supplied lightstrike thresholds.
