Automated Supplier Safety for Craft Breweries & Hops
Protect brand integrity and prevent catastrophic batch recalls from grain to glass. Evidlane automates craft brewery raw material quality: gating maltster vomitoxin (DON) to eliminate beer gushing, monitoring hop storage index (HSI) degradation and pesticide MRLs, verifying yeast STA1 diastaticus-negative PCR assays, and streamlining FSMA 507 spent grain compliance.

Core Compliance Infrastructure
Engineered for Commercial Craft Brewing Quality
Craft brewing combines biochemical enzymatic mashing with microbiological fermentation. Even minor raw material variances create irreversible off-flavors, stuck fermentations, or packaged product recalls.
Malt DON, Hydrophobin & Gushing Gating
Automated OCR extraction of maltster CoAs: deoxynivalenol (DON < 0.5 ppm), extract FGDB (>80%), Diastatic Power, and Friability. Preventing catastrophic primary beer gushing and stuck mashing.
Hop Alpha Decay & Pesticide MRLs
Track ASBC Hops-6 alpha/beta acids, oil fractions, and Hop Storage Index (HSI < 0.32). Automate first-order cold storage degradation calculations and screen 400+ pesticide residues against EPA tolerances.
Yeast Purity & STA1 Diastaticus Gating
Enforce mandatory supplier certification of negative STA1 glucoamylase PCR assays to eliminate secondary fermentation and exploding cans. Monitor lactic bacteria (LAB) and anaerobic wild bacteria.
TTB Formulas & FSMA 507 Spent Grain
Manage TTB formula approval certificates for fruit purees and botanical adjuncts. Document sanitary spent grain (BSG) holding tank procedures under FSMA Animal Food rules (21 CFR Part 507).

Hop Storage Kinetics & Real-Time Bitterness (IBU) Precision
Hop bittering acids (alpha acids: humulone, cohumulone, adhumulone) degrade over time via oxidative cleavage into hard resins. The rate of loss depends directly on temperature and the Hop Storage Index (HSI). Evidlane models real-time alpha acid decay to enable precision recipe bitterness compensation.
Formula 1: First-Order Hop Alpha Acid Degradation Equation
Where α_0 is the harvest alpha acid %, t is storage duration (days), and k_decay is the temperature-dependent rate constant. At 20°C ambient storage, alpha acids degrade 4× faster than at -4°C cold storage.
Formula 2: Dynamic Wort Bitterness (IBU) Compensation Model
Where U(time, SG) is the utilization factor based on boil duration and wort specific gravity. Evidlane dynamically updates W_hop requirements so the head brewer maintains exact target IBU across aging hop lots.

Frequently Asked Questions
Expert Guidance on Brewery Safety & Quality
Detailed answers to complex brewing science, regulatory, and supplier compliance questions.
1. How does Evidlane monitor barley malt mycotoxins and prevent beer gushing?
Fusarium species infecting brewing barley produce hydrophobic proteins (hydrophobins) alongside deoxynivalenol (DON/vomitoxin). Hydrophobins act as carbon dioxide nucleation sites, triggering violent spontaneous gushing upon opening packaged beer. Evidlane parses maltster CoAs via AI OCR, enforcing strict thresholds (DON < 0.5 ppm / 500 µg/kg per EU 2023/915) before bulk pneumatic grain silos are loaded.
2. How are hop pellet alpha acids, storage index (HSI), and pesticide residues verified?
Evidlane extracts ASBC Hops-6 alpha/beta acid percentages, essential oil profiles, and the Hop Storage Index (HSI target < 0.32; values > 0.40 indicate oxidized bitter acids). It matches multi-residue pesticide analytical screens against US EPA 40 CFR Part 180 tolerances and EU MRLs, ensuring imported hops comply with clean brewing standards.
3. How does the platform screen commercial yeast pitches for wild yeast and Saccharomyces diastaticus?
Saccharomyces cerevisiae var. diastaticus produces extracellular glucoamylase, which hydrolyzes non-fermentable dextrins in packaged beer, causing dangerous package over-pressurization (exploding cans) and off-flavors. Evidlane requires yeast propagation labs to provide certified negative STA1 PCR gene assay results and lactic acid bacteria (Lactobacillus/Pediococcus) counts < 1 CFU per 10^7 cells.
4. What regulatory obligations apply to brewer spent grain under FSMA 21 CFR Part 507?
When spent brewer grain (BSG) is diverted to local farmers for cattle feed, breweries fall under FSMA Current Good Manufacturing Practice for Animal Food (21 CFR Part 507). Evidlane documents sanitary holding silo maintenance, clean transport agreements, and guarantees that toxic processing chemicals, CIP cleaners, or glass contamination do not enter livestock feed.
5. Does Evidlane verify malt Diastatic Power (DP), Friability, and Kolbach Index?
Yes. Evidlane indexes maltster technical specifications: Fine Grind Dry Basis extract (FGDB ≥ 80%), Diastatic Power (DP ≥ 120–140 °Lintner for North American 2-row), Friability (≥ 80%), Kolbach Index (38–45%), and beta-glucan (< 140 mg/L) to prevent stuck lautering and haze instability.
6. How are nitrosamines (NDMA) controlled in roasted and specialty malts?
N-nitrosodimethylamine (NDMA) forms during direct-fired malt kilning when grain amines react with combustion nitrogen oxides (NOx). Evidlane verifies that maltster CoAs confirm NDMA concentrations remain below US FDA action levels (< 2.5 µg/kg / ppb) and European Brewery Convention (EBC) standards.
7. How does Evidlane assist with TTB formula approvals for specialty brewing adjuncts?
For craft beers containing fruits, spices, botanicals, or natural extracts, the TTB (Alcohol and Tobacco Tax and Trade Bureau) requires formula approval prior to label submission (COLAs). Evidlane links TTB formula approval IDs directly to raw material lots and supplier ingredient declarations.
8. Can Evidlane calculate hop alpha acid degradation during warehouse cold storage?
Yes. Using first-order degradation kinetics based on temperature logs and initial Hop Storage Index (HSI), Evidlane calculates real-time alpha acid decay for stored hop boxes, enabling head brewers to dynamically adjust boil and dry-hop dosing to maintain consistent recipe IBUs.
9. How does Evidlane connect with craft brewery ERP systems (Ekos, OrchestratedBeer, SAP)?
Evidlane provides open RESTful APIs and real-time webhook listeners. Inbound grain and hop purchase orders in your brewery ERP trigger automated CoA parsing in Evidlane, writing back QA release tokens or placing non-compliant lots into automated inventory quarantine.
10. How fast can a regional packaging brewery or brewpub chain implement Evidlane?
Implementation typically completes within 10 to 14 business days. Evidlane includes pre-loaded specification templates for base malts, roasted specialty malts, T-90 and cryo hop pellets, liquid yeast pitches, brewing salts, finings, and fruit purees.
