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:

  • Asset purchase & license transfer packs (NM ABC, TTB)
  • Sensor retrofit BOM finalised
  • Brew Add‑On NFT smart‑contract draft on Base testnet

Cap-Ex Funding: —

2

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)

Soft-Opening

Token-holders + 1 guest, first mash-in livestream; crowler pick-up.

Monthly

Short-Form Video

60-sec reels of sensor data visibly updating NFT metadata; cross-post X/Instagram.

Quarterly (Phase 2)

Collab Brew Ballot

Internal poll (SurveyMonkey) – results hashed to Base; winning recipe brewed + NFT art drop.

Banquet Center
