Beer and Liquor Analysis

Independent Testing for Alcohol Quality, Safety, and Disputes

Phase 4 Services provides third-party laboratory testing for beer, spirits, and other alcoholic beverages. We help breweries, distilleries, and regulators evaluate product integrity, detect contamination, and resolve labeling or quality concerns.

We serve clients in Massachusetts, New York, Maine, and throughout the U.S.

What We Test

Alcohol Content Verification

We analyze alcohol-by-volume (ABV) using validated instrumentation to confirm label accuracy and compliance with state and federal standards.

Contamination and Adulteration

Our lab detects microbial contamination, chemical adulterants, heavy metals, and unknown substances that may affect product safety, shelf life, or taste. We support investigations of off-flavors, spoilage, and consumer complaints.

Label and Regulatory Compliance

We provide analytical chemistry testing to support regulatory filings and ensure products meet TTB, FDA, and state-level requirements. Our reports are suitable for both internal QA and third-party audits.
