What a Microbrewery actually does
Converts a brewer's 3-bullet sensory log into tasting notes and daily Instagram posts, then powers a Lovable tap-list app that replaces Ekos for under-300-bbl operations.
A microbrewery is the sub-300-barrel-per-year scale — often one or two people, a single tasting room, very limited wholesale, and an operations stack where Ekos ($200–$500/mo) starts to feel like enterprise software for a garage-scale operation. At this size, the real time bleeds are: Instagram and Untappd for each new batch, taproom event copy, and the never-ending FAQ ('are you open today?', 'got hazies on tap?'). A Lovable tap-list + tasting-note app with a public 'what's on tap' widget covers the same functional ground as an Untappd for Business subscription for $25/mo, and Claude Haiku 4.5 writes batch tasting notes in 3 minutes from a brewer's sensory bullets.
The honest verdict at sub-300-bbl scale: Ekos is overkill. Spreadsheet-based batch records plus a Google Sheets TTB log is defensible at this volume, and a Lovable app handles the consumer-facing tap list. ChatGPT free drafts the Instagram captions and event copy. The entire stack runs $25–$50/mo. What AI does NOT do: it doesn't replace the government filings (TTB Brewer's Notice + monthly BROP are federal obligations regardless of scale), and it doesn't generate verified ABV/IBU values for labels — those are measured in the brewery, not generated by a model.
AI capabilities involved
Batch tasting note generation from sensory bullets
Daily Instagram tap-list captions and Untappd descriptions
Taproom event copy (trivia, brewer's nights, can releases)
Instagram DM FAQ auto-replies via chatbot
Who uses this
- 1–2 person microbrewery doing $150K–$500K with a single tasting room and limited or no wholesale
- Homebrewer who opened a commercial tasting room and wants to avoid the cost of enterprise brewery software
- Nano-brewery owner who manages both the brewing and all the marketing without a separate hire
- Small taproom operator who wants a public 'what's on tap' widget on their website without paying $50–$200/mo for Untappd for Business
SaaS alternatives on the market
Real products you can sign up for today — with current 2026 pricing, honest pros and cons.
Square for Restaurants
A microbrewery doing simple counter service with no tab management or table-service complexity
Free tier (2.6% + $0.10 per transaction)
$0/mo (free tier) or $69/mo (Plus tier)
Pros
- +Zero monthly cost on the free tier — handles card payments, basic inventory, and daily transaction reports
- +Tap-to-pay hardware ($49 card reader or free with account) is frictionless for taproom tab management
- +Integrates with Mailchimp, QuickBooks, and most email tools without extra setup
- +Free tier is functionally adequate for a single-tap-point tasting room under 100 transactions/day
Cons
- −Free tier lacks tab management, tip options, and table mapping — requires Plus tier ($69/mo) for full taproom POS functionality
- −Not designed for brewery-specific needs: no beer-style categories, no batch tracking, no Untappd integration
- −Tab management for group visits requires Plus tier — a common taproom use case
- −Support is chat/email only — slow during busy taproom hours
Untappd for Business
A microbrewery whose primary discovery channel is the Untappd community app — worth paying for if Untappd check-ins are a meaningful traffic driver to the taproom
Limited free venue claim
$50/mo
Pros
- +12M+ active users on the Untappd consumer platform check in and discover beers at participating venues
- +Digital tap list syncs to TVs in the taproom and to the Untappd consumer app simultaneously
- +Free venue claim allows basic check-ins and menu listing — often sufficient for nano-breweries
- +QR-code menu integration replaces printed tap sheets
Cons
- −At $50–$200/mo, paid tier cost is comparable to or exceeds the Lovable app that does the same job for $25/mo
- −Platform check-in reviews are permanent — a bad batch's negative check-ins can't be removed
- −No admin panel for batch tasting notes integrated with your own website — Untappd owns the display
- −Paid plan required for real-time tap list sync and multiple manager logins
The AI stack
A microbrewery needs one lightweight AI text model for tasting notes and social copy, plus a Lovable tap-list app. Nothing more. The operations and TTB compliance layer is spreadsheets and a federal filing, not AI.
Batch tasting notes and Instagram captions
Converts a brewer's 3-bullet sensory log into publishable tasting notes for the tap-list app and Untappd, plus daily Instagram captions
Claude Haiku 4.5
$1/$5 per M tokensAll routine tasting notes, Untappd descriptions, and Instagram captions at sub-300 bbl/yr scale
Gemini 3 Flash
$0.50/$3.00 per M tokens (free tier available)Daily Instagram tap-list posts and event copy where free is preferable to paid

$0.20/$1.25 per M tokensManychat Instagram DM FAQ auto-replies at high volume
Our pick: Claude Haiku 4.5 via Claude.ai free tier for tasting notes and weekly content batches. Gemini 3 Flash free tier for daily Instagram. GPT-5.4 nano only if setting up a Manychat FAQ auto-reply workflow for Instagram DMs.
Tap-list and tasting-note app
Public 'what's on tap' widget with batch tasting notes, taproom hours, and event calendar — replacing the Untappd for Business paid tier
Lovable + Supabase
$25/mo Lovable Pro + $0 Supabase free tierAny microbrewery where Untappd for Business at $50–$200/mo is the primary reason to pay and the community check-in feature isn't driving meaningful taproom traffic
Our pick: Build the Lovable tap-list app this weekend. The free Untappd venue claim handles community check-ins; the Lovable app handles the public tap list, tasting notes, and hours display on your own website and in the taproom on a TV.
Reference architecture
Two lightweight parallel workflows: a browser-based Claude/ChatGPT workflow for tasting notes and social copy, and a Lovable-built tap-list app that the owner updates from an admin panel. No API integration needed; no pipeline; no code required beyond the Lovable build weekend.
Brewer logs 3 sensory bullets per batch in a Google Sheet batch record
Google Sheets (TTB batch record)Batch record includes: batch number, brew date, grain bill, hop additions, yeast strain, OG/FG readings, calculated ABV, IBU estimate, and 3 sensory bullets from the post-fermentation tasting. This is the TTB traceability record — must be maintained regardless of what software you use.
Owner pastes sensory bullets into Claude Haiku 4.5 or ChatGPT
Claude.ai browser or ChatGPT.comSaved prompt contains the brewery name, voice guidelines, and current tap list for context. Owner pastes the 3 sensory bullets and requests tasting note, Untappd description, and Instagram caption in one pass. Takes 3 minutes.
Approved tasting note entered into the Lovable admin panel
Lovable-built admin panel (Supabase-backed)Owner logs into the password-protected admin panel, adds the new beer with: name, style, ABV (from batch record — not from AI), IBU (from recipe), tasting note (Claude draft), and status (on-tap, coming soon, off-tap). Public tap-list page updates immediately.
Instagram caption from Claude posted via Canva template
Canva free or Pro + InstagramCaption goes into a Canva social template with the beer name and brewery logo. Post is either scheduled via Meta's free creator tools or posted directly. Gemini free tier handles the daily ambient content; Claude-drafted copy is used for new batch launch posts.
Taproom TV displays the public tap-list page as a live widget
Lovable public tap-list page on a tablet or Smart TV browserThe same URL that customers visit on their phone is displayed full-screen on the taproom TV — no separate digital menu subscription needed. When the owner updates the Supabase database, the TV updates automatically on page refresh.
Event copy drafted in ChatGPT and posted to Instagram, Facebook, and Eventbrite
ChatGPT free + Instagram + FacebookOwner provides event details (trivia night, can release, brewer's table date/time) and ChatGPT drafts the Instagram caption, Facebook event description, and email subject line in one pass. Entire workflow takes 5 minutes per event.
Estimated cost per request
~$0.0005 per tasting note at Claude Haiku 4.5 standard rate (approximately 200 input + 150 output tokens per short tasting note). 100 batch releases per year costs ~$0.05 in API tokens — less than a single can of beer.

Calculator notes
- The entire recommended stack at sub-300 bbl/yr runs $25/mo (Lovable Pro only) — everything else is free tier
- Square for Restaurants free tier handles taproom POS adequately until you need tab management or table mapping (Plus tier $69/mo)
- Manychat at $15/mo flat rate is optional — add only if Instagram DM volume ('are you open?', 'got hazies?') is taking more than 30 minutes/week
- The TTB BROP filing has no software cost — a Google Sheets batch record gives you the data you need; your accountant does the federal filing
Build it yourself with vibe-coding tools
This weekend, build a Lovable tap-list app with a public 'what's on tap' page, an admin panel to update batches from your phone, and a Supabase database. Tonight, paste your next batch notes into ChatGPT and have a tasting note in 3 minutes.

You'll need
Starter prompt
Build me a tap-list and tasting-note app for my microbrewery. Requirements: 1. PUBLIC TAP-LIST PAGE (yourbrewery.com/taps): Shows our current beers on tap with: - Beer name, style, ABV%, IBU - A 2–3 sentence tasting note (I'll enter this from the admin) - Status badge: On Tap / Coming Soon / Off-Tap - A pint glass icon and our taproom hours Optional: embed this as a widget (iframe) on our existing website 2. EVENTS SECTION: A simple list of upcoming taproom events (date, event name, 1-sentence description). I'll update this from the admin. 3. INSTAGRAM DM FAQ WIDGET: A simple 'Visit us' block with address, hours, phone, and a 'What's on tap?' link to the tap list. 4. ADMIN PANEL (password-protected, mobile-friendly): - Add/edit beers: name, style, ABV, IBU, tasting note, status (on-tap / coming soon / off-tap), photo upload optional - Reorder beers by drag-and-drop - Add/edit events: date, name, description - Update taproom hours (in case of special hours) 5. TV-FRIENDLY VERSION: A '/tv' URL that displays the tap list in a clean, large-font format suitable for display on a taproom TV — auto-refreshes every 5 minutes. Backend: Supabase (PostgreSQL). No payments, no user auth for customers — admin only. Style: [describe your brewery aesthetic — e.g., 'industrial, dark background, hoppy green accents, our logo at top']. Mobile-first for admin; desktop-optimized for the TV view.
Paste this into Lovable
Follow-up prompts (run in order)
- 1
Add a 'mug club' email signup form to the tap list page — just name and email, saves to Supabase, and sends me a notification email via Resend when someone signs up. Show the current member count on the page ('Join 87 mug club members').
- 2
Add a simple batch log to the admin: a table showing all past beers with brew date, batch size (gallons), TTB batch number, and a 'public / archived' toggle. This replaces my Google Sheet batch log. Export to CSV button for TTB filing prep.
- 3
Add an Instagram story preview generator: when I enter a new beer in the admin, automatically generate a social-ready image card (beer name, style, ABV, our logo, brand colors) that I can download and post directly to Instagram Stories. Use the Supabase image URL and Canvas API.
Expected output
A live tap-list page at yourbrewery.com/taps, a TV display at /tv, an admin panel you can update from your phone in 60 seconds per beer, and a tasting-note workflow that takes 3 minutes per batch — replacing Untappd for Business at $50–$200/mo and Ekos at $200+/mo for the consumer-facing use cases.
Known gotchas
- !Never use AI to generate ABV or IBU values — these must come from your actual batch measurements (gravity readings, recipe calculation) and must be accurate for any packaged label claim submitted to TTB
- !The Lovable app does NOT replace TTB Brewer's Notice compliance or monthly BROP filings — those are federal obligations you handle separately via Google Sheets batch logs and your accountant
- !Auto-refresh on the TV display (/tv URL) requires testing on your actual taproom TV — some Smart TV browsers cache aggressively and won't update automatically
- !The Lovable admin panel is password-protected but not enterprise-secure — don't store customer payment data or personal health information in Supabase
- !AI tasting notes occasionally add style descriptors you didn't include ('this hazy IPA has notes of stone fruit') when you only gave it hop variety names — always taste-verify before publishing
- !Manychat's Instagram DM integration requires your Instagram account to be a Professional Account and connected to a Facebook Business Page — verify this before building the FAQ auto-reply flow
Compliance & risk reality check
A microbrewery carries the same federal TTB obligations as a regional craft brewery — Brewer's Notice, monthly BROP, COLA per packaged label — but at a scale where the compliance burden is real even if the SaaS overhead is not justified. AI has no role in any of these regulatory processes.
TTB Brewer's Notice + monthly Brewer's Report of Operations (BROP)
Any commercial brewery must hold a TTB Brewer's Notice before producing beer for sale. The monthly BROP reports all production, removals, and tax payments. At sub-300 bbl/yr, a Google Sheets batch log with brew dates, batch sizes, removal dates, and sales channels gives you the data needed for the BROP. The filing itself is submitted through TTB's Permits Online — not via Ekos or any app. Late or inaccurate BROPs trigger penalties.
Mitigation: Maintain a Google Sheets batch log with all production data by batch number. Have your accountant or a TTB-familiar bookkeeper review and file the monthly BROP via TTB Permits Online. AI has no role in this process.
TTB COLA per packaged SKU (canned, bottled, or crowler labels)
Taproom-only draft beer is typically exempt from TTB COLA requirements. However, any beer packaged in cans, bottles, or crowlers (even for on-premise sale to-go) requires COLA approval. The COLA review checks ABV accuracy, style designation, origin claims, and prohibits health-related language. AI-generated label copy is not COLA-ready — every label claim must be human-reviewed.
Mitigation: For any packaged format, use a TTB-knowledgeable label designer or compliance consultant before submitting COLA. Draft-only taproom operations that don't package for to-go sale typically avoid this requirement — confirm your state's rules with your state ABC board.
State ABC + local taproom permits
Every commercial brewery requires a state Alcoholic Beverage Control license for the taproom (on-premise consumption) and potentially a separate retail license if selling packaged beer to-go. Local municipalities may add a business license or special-use permit layer. These are non-negotiable; operating without them is a criminal violation.
Mitigation: Consult your state ABC office before opening or before adding to-go package sales. Most states have a small-brewer or brewpub license tier that streamlines the taproom permit. Fees range from $200–$5,000 depending on state.
Federal and state excise taxes
Federal excise tax on beer is $7/barrel for the first 60,000 barrels (craft producer rate). At 150 bbl/yr, federal excise tax is approximately $1,050/year — a real cost that must be reported and paid via TTB monthly. Most states add a state excise tax layer. These are paid on 'removals from bond' (when beer leaves your possession for sale), not on production.
Mitigation: Include federal and state excise tax in your batch cost accounting from day one. Your accountant should review and file both federal and state excise returns monthly. Failure to pay excise tax is a federal felony — not a civil matter.
ABV accuracy on all consumer-facing materials
Even for taproom-only draft beer, ABV claims on tap lists, social media, and Untappd descriptions should be accurate — both for consumer trust and because packaged versions will need accurate COLA claims. AI will sometimes round, approximate, or guess ABV values if you don't provide the measured figure.
Mitigation: Always provide the measured ABV from your hydrometer or refractometer readings in any AI prompt. Instruct Claude or ChatGPT explicitly: 'The ABV is X.X%. Do not round or change this value.' Verify all AI output for any ABV reference before publishing.
Build vs buy: the real math
8–12 weeks

One-time investment
Never, below 300 bbl/yr; 36–48 months if growing toward 1,000 bbl
Breakeven vs buying
A custom tap-list, mug-club, and DTC platform from RapidDev costs $13K–$25K. At $150K revenue (a typical sub-300-bbl microbrewery), there is no version of this math where a custom build recoups its cost within a reasonable timeframe — the Lovable app at $25/mo covers the consumer-facing use case indefinitely for $300/year. If the microbrewery is on a clear growth path toward 1,000 bbl/yr and $500K+ revenue, the economics shift: at $500K revenue with a 5% DTC lift from a custom platform, you get $25K/year and a 12–20 month payback. But at sub-300 bbl scale, the Lovable MVP is the right call — build Lovable now and revisit custom when you've grown past 500 bbl/yr and the operations complexity genuinely exceeds what Supabase + a Lovable app can handle.

Frequently asked questions
How much does it cost to build an AI solution for a microbrewery?
The recommended stack costs $25/mo — Lovable Pro for the tap-list app, everything else free (ChatGPT, Canva free, Mailchimp free, Square free tier). A custom RapidDev build runs $13,000–$25,000, only justifiable if planning growth past 500 bbl/yr. Ekos + Untappd for Business + Square runs $270–$720/mo — significantly more than necessary at sub-300 bbl scale.
How long does it take to ship a tap-list app for a microbrewery?
One weekend. The Lovable MVP — public tap-list page, TV display, admin panel — takes approximately 3–6 hours of prompt iteration to build. Testing on your actual taproom TV takes another few hours. Total time to live: 1 weekend plus 1–2 weeks of soft testing. Tonight: paste your first batch notes into ChatGPT for a tasting note in 3 minutes.
Can RapidDev build a custom app for my microbrewery?
Yes — RapidDev has shipped 600+ applications. For microbreweries specifically, we'd want to have an honest conversation about scale: at sub-300 bbl/yr, the Lovable MVP covers your needs for $25/mo, and a $13K–$25K custom build is difficult to justify. If you have a clear growth plan to 1,000 bbl/yr and want to build the infrastructure now, book a free 30-minute consultation at rapidevelopers.com.
Can I skip Ekos at sub-300 bbl/yr?
Yes, at most micro-brewery scales. Ekos at $200–$500/mo is designed for 500–3,000 bbl/yr operations with complex batch tracking, distributor invoicing, and multi-product TTB BROP data. At sub-300 bbl/yr, a Google Sheets batch log (brew date, batch number, grain bill summary, OG/FG, production volume, removal dates) gives you the data you need for the monthly BROP. You still need to file the BROP via TTB Permits Online — Ekos just automates the data collection for that filing.
Will the Lovable tap-list app replace Untappd for Business?
For the tap-list display and tasting notes on your own website and taproom TV: yes. The Lovable app covers those use cases for $25/mo versus Untappd for Business at $50–$200/mo. The Lovable app does NOT replace Untappd's consumer community app — 12M+ users check in on Untappd, and those community check-ins drive taproom discovery. Claim your free Untappd venue profile (free tier) and keep the Lovable app for your own website and TV display.
Can AI help with TTB BROP filings or Brewer's Notice compliance?
No. The TTB Brewer's Notice is a federal permit; the monthly BROP is a federal tax document. AI cannot file them, verify batch data accuracy, or assess your compliance status. Maintain a Google Sheets batch log with all production data, and have your accountant or a TTB-familiar bookkeeper review and file the monthly BROP via TTB Permits Online. Failure to file or inaccurate filings trigger federal penalties.
What AI tools are best for writing taproom event copy?
ChatGPT free tier handles all standard taproom event copy — trivia nights, can releases, brewer's tables, and mug-club announcements — in about 2 minutes per event. Give it the event name, date, time, and any special details, and it returns an Instagram caption, Facebook event description, and email subject line in one pass. Claude Haiku 4.5 is slightly better for more evocative brand copy, but for practical taproom announcements ChatGPT free is indistinguishable.
