ProofLogic provides calculator tools for production planning, estimation, and workflow support. By using the service, you acknowledge and agree that all calculator outputs are estimates and must be independently verified before being relied upon for production, compliance, tax, labeling, reporting, inventory, safety, or operational purposes.
ProofLogic is not an official compliance system, tax filing system, government recordkeeping platform, or substitute for approved gauging procedures.
Calculator outputs are provided for informational and planning purposes only. Results may vary based on input accuracy, instrument calibration, temperature, measurement method, rounding, table interpretation, production conditions, and other variables.
You are solely responsible for confirming all proof, volume, weight, water-addition, tax, labeling, reporting, inventory, and compliance values using appropriate instruments, approved procedures, and applicable legal requirements.
You must independently verify all calculator results before using them in any production, compliance, tax, labeling, reporting, or business decision.
Do not rely on ProofLogic as your sole source of truth. Final production and compliance decisions should be based on your own verified measurements, required records, applicable laws, and professional judgment.
Never add the full estimated water amount at once.
Water should be added gradually. Mix thoroughly, agitate as appropriate, allow the batch or sample to homogenize, recheck proof, and repeat as needed until the target proof is reached.
Actual water-addition requirements may vary due to proofing behavior, temperature, dissolved solids, barrel influence, sugar or flavor additions, measurement method, instrument calibration, and production conditions.
Certain calculators may use or reference TTB Gauging Manual table-based methodology, including materials from TTB Publication 5110.6 and related federal gauging guidance.
The use of TTB table logic does not mean that ProofLogic is approved, endorsed, certified, or operated by the Alcohol and Tobacco Tax and Trade Bureau or any other government agency.
ProofLogic is not a substitute for a DSP's required records, approved gauging procedures, tax determinations, formula requirements, label approvals, reporting obligations, or compliance practices.
ProofLogic does not provide legal, tax, compliance, accounting, engineering, safety, production, or regulatory advice.
You should consult qualified professionals, regulators, or compliance advisors where appropriate, especially before making decisions that may affect tax liability, regulatory filings, label claims, product release, production records, or business operations.
You are responsible for: - Providing accurate inputs; - Using calibrated instruments; - Confirming measurements under appropriate conditions; - Understanding the limitations of calculator outputs; - Maintaining required records; - Complying with applicable federal, state, and local laws; - Making final production, compliance, tax, safety, and business decisions.
ProofLogic is provided on an "as is" and "as available" basis. We do not warrant that calculator outputs will be error-free, complete, current, suitable for your specific use case, or accepted by any regulatory authority.
To the fullest extent permitted by law, we disclaim all warranties, express or implied, including warranties of accuracy, reliability, merchantability, fitness for a particular purpose, and non-infringement.
To the fullest extent permitted by law, ProofLogic, its owners, operators, affiliates, employees, contractors, and service providers are not liable for any damages, losses, penalties, regulatory issues, production errors, tax consequences, business interruption, or compliance problems arising from your use of the service or reliance on calculator outputs.
This includes, but is not limited to, issues related to proofing, dilution, volume measurement, weight conversion, production records, tax reporting, label claims, inventory records, product release, safety, or operational decisions.
By using ProofLogic, you acknowledge that calculator outputs are estimates, that independent verification is required, and that you remain solely responsible for all final production, compliance, tax, reporting, labeling, inventory, safety, and business decisions.
