Brettanomyces 4-EP Risk Checker
Classify measured 4-ethylphenol against caller-supplied noticeable and high thresholds; sensory response varies with wine matrix, other volatile phenols, and the assessor.

Brettanomyces 4-EP Risk Checker: Classify measured 4-ethylphenol against caller-supplied noticeable and high thresholds; sensory response varies with wine matrix, other volatile phenols, and the assessor.
When to use Brettanomyces 4-EP Risk
Use this oenology calculation to document or plan a defined fermentation, blending, adjustment, stabilization, aging, packaging, sensory, or cellar operation from measured wine parameters.
- High threshold (µg/L)
- Concentration at or above which the result is high.
- Noticeable threshold (µg/L)
- Concentration at or above which the result is noticeable.
- 4-EP (µg/L)
- 4-ethylphenol measured in the wine.
How Brettanomyces 4-EP Risk works
Classify measured 4-ethylphenol against caller-supplied noticeable and high thresholds; sensory response varies with wine matrix, other volatile phenols, and the assessor. 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
- Risk level
- One of low, noticeable, or high.
Limitations and assumptions
- 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.
Alternative or Complementary approaches
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.
