The Graine Ledger × Sobremesa
Integrated Brewing Roadmap (2025 – 2028) Prepared for executive sign‑off – June 2025
1. Purpose & Vision
Purpose
Transform Sobremesa Restaurant, Brewery & Banquet Center into the operational headquarters of The Graine Ledger (TGL), adding a beer utility to barrel‑token holders and showcasing Industrial‑Automation‑as‑a‑Service (I3AS) in a live hospitality environment.
Vision
By 2028, operate a sensor‑rich, largely self‑running 30‑50 bbl brewery whose production data immutably updates on Base L2, with revenue and product benefits delivered to token holders through a Centralized Autonomous Organization (CAO) framework.
2. Strategic Objectives & KPIs
3. Governance Model – CAO (Centralized Autonomous Organization)
Authority
Board‑approved management retains final decision rights; smart contracts automate pre‑defined actions only.
Smart-Contract Layer
  • TGL‑Barrel Token (2023) – unchanged.
  • TGL‑Brew Add‑On NFT (2025) – gated mint for existing tokens; combo tokens for new sales.
  • Redemption Contract – burns or decrements beer allotments, writes redemption hash to Base.
Automation Scope
  • Token minting/transfer
  • Allotment decrement & on‑premise POS reconciliation
  • Crowler & shipment claim verification
  • Revenue splits (Phase 3)
Human Oversight
  • Managing Director countersigns cap‑ex > $100K
  • Financial Controller batch‑reconciles on‑chain vs. QuickBooks monthly
  • Legal/Compliance signs off before any contract upgrade
4. Roadmap Timeline
1
Phase 0 – Pre-Close (Jun-Jul 2025)
Core Deliverables:

Cap-Ex Funding: —

Phase 1 – Pilot (Aug 2025-Jan 2026)
Core Deliverables:
  • Install 5 bbl brewkit + temp, gravity, pH, CO₂ sensors
  • Launch "Brewer's Dozen" benefit (12 pints or crowlers/yr/token)
  • Deploy live IoT ➜ Chainlink ➜ Base batch feed
  • Token‑gated banquet booking portal alpha
Cap-Ex Funding: $125K TGL treasury
3
Phase 2 – Community Collab (Feb-Dec 2026)
Core Deliverables:
  • Quarterly Collab Brew Ballot (run internally, results written on‑chain)
  • Batch‑specific NFTs with art + brewing telemetry
  • DTC shipping (NM only) via ShipCompliant webhook ➜ Base hash
Cap-Ex Funding: $80K (Add-On NFT sale proceeds)
4
Phase 3 – Distributed Production (2027)
Core Deliverables:
  • 3 contract‑brew partners (alternating proprietorship)
  • Smart‑contract escrow splits wholesale revenue ➜ token wallets (ETH/USDC)
  • Traveling Barrel program: age beer in emptied TGL whiskey barrels
Cap-Ex Funding: $200K (50% retained earnings, 50% bank line)
5
Phase 4 – Automated Flagship (2028)
Core Deliverables:
  • Robotic grain handling, CIP, canning
  • On‑chain HACCP & QC logs
  • Visitor Innovation Lab tours
Cap-Ex Funding: $4-6M (60% SBA/CRE loan, 25% operating cash, 15% strategic investor)
5. Token‑Economics & Holder Utility
Eligibility
1:1 free mint for each existing Barrel Token during 60‑day window; new investors purchase combo token (Barrel + Brew) thereafter.
Annual Allotment
12×16 oz pours or 12×32 oz crowlers (redeem on‑premise or ship where legal).
Transferability
Fully transferable; remaining allotment travels with NFT.
Secondary Fees
2.5% to TGL treasury; 1% to artist; enforced at contract level, payable in ETH (Base).
Expiration
Allotment resets every 365 days; unredeemed balance burns.
Future Income Share (Phase 3)
Optional opt‑in staking of Brew NFT to receive % of contract‑brew revenue; treated as income‑sharing token (Reg D).
6. Tech & Automation Stack
7. Marketing & Community Engagement Plan
T-60d (Jun 2025)
Holder Announcement
"From Barrels to Brews" email + video teaser showing IoT sensors writing to Base.
Take-Over Week (Aug 2025)

Monthly
Short-Form Video
