Cru Uncorked’s playful "Sommelier Showdown" that pitted three human sommeliers against Microsoft Copilot produced a narrow victory for the humans — but the experiment delivered a far richer takeaway: AI can reliably suggest classical, crowd-friendly pairings, yet it still leans on human data, inventory grounding and interaction to reach restaurant-ready usefulness.
Background / Overview
Cru Uncorked is a fine‑dining restaurant housed in a countryside chateau just outside Cleveland that maintains an extensive cellar and an experiential program built around wine education and live pairing events. The restaurant’s recurring Sommelier Showdown — a live, blind-pouring, guest‑voted tasting where the house sommeliers compete Iron‑Chef style — was expanded in 2025 to include an AI competitor after president and sommelier Chris Oppewall experimented with ChatGPT and ultimately chose Microsoft Copilot for this task. The premise: present two blind pours per course (one chosen by a sommelier, one by AI), let guests vote round‑by‑round, and see whether algorithmic pairings win palates as often as the trained professionals. Cru Uncorked’s event pages describe the ongoing series of these showdowns and confirm the restaurant’s embrace of interactive wine programming.The takeaways are straightforward but consequential. On the one hand, the sommelier team narrowly won the evening’s tally; on the other, AI produced at least one dominant winning pairing and tied another, demonstrating that off‑the‑shelf assistant models can reach very good — sometimes excellent — suggested matches when the menu and constraints are well explained. Coverage of the event in broader press picked up the novelty and the results, underscoring why restaurants and beverage teams are experimenting with AI as a helper rather than a replacement.
What happened at Cru Uncorked: the showdown, course by course
Cru Uncorked staged a four‑course tasting menu with blind pairings from three resident sommeliers and from Microsoft Copilot. The basic format was simple and decisive: each course was paired twice (or more, depending on the round), pours were served blind, and guests cast a single vote for the pairing they preferred.Highlights reported from the night (as described by the restaurant and syndicated press) include:
- Course 1 — Seared tuna with wasabi cream, cucumber, avocado and sesame: Copilot and a sommelier tied, showing parity on a delicate, aromatic fish course.
- Course 2 — Iberico pork with butternut squash risotto and goat cheese fondue: the sommeliers prevailed decisively with a Pinot Noir choice.
- Course 3 — Prime CAB strip with mushroom purée and peppercorn sauce: Copilot’s Bordeaux pick beat the sommelier’s Syrah in guest votes.
- Course 4 — Artisan cheeses: a close finish with the sommelier group edging out AI.
Note on numeric claims: the original account that lists point totals per course is available in the article text provided; independent online access to the full Restaurant Business story was restricted during verification attempts, so the specific numeric vote totals reported in that piece should be considered sourced to the restaurant’s recounting as published. Corroborating coverage by other outlets confirms the event and the broad winners, but not every point‑by‑point figure. Where exact vote tallies are cited, they originate from the event narrative supplied by the restaurant.
Why AI succeeded where it did — and where it stumbled
Strengths of Copilot-style suggestions
- Consistency and classic knowledge: AI systems trained on a broad corpus of culinary and wine writing will reliably surface canonical pairings — e.g., Pinot Noir with pork or red Bordeaux with fatty beef — which are excellent starting points for guest palates. The Cru Uncorked Copilot example that won the beef course by recommending a Pauillac‑style Bordeaux is a textbook illustration. Château Pontet‑Canet (the Bordeaux Copilot suggested) is a well‑known Pauillac estate classified in the 1855 classification as a Fifth Growth, and its wines are commonly recommended with rich, peppery beef dishes.
- Speed and budget awareness: AI can quickly search a menu, suggest multiple pairings that meet price constraints or inventory rules (if that data is provided), and produce alternative options within seconds. At Cru Uncorked, Oppewall noted Copilot tended to stay “within budget” about 80% of the time when given the restaurant context, reflecting that conversational assistants can be constrained by price or availability parameters when provided. (That precise “80%” figure comes from the host’s recounting of the event; independent, repeatable verification of that metric would require a controlled test.)
- Familiarity with canonical descriptors: AI can synthesize tasting notes, match aromatics and textures, and propose pairings built on synergy (acidity vs. fat, tannin vs. protein, sweetness balancing spice). Those rules are stable and well represented in training corpora, so generative assistants frequently return sensible, defensible answers.
Where AI still struggles
- Inventory grounding and availability: AI frequently recommends wines that sound right but may not be in a specific cellar. Cru’s team found roughly a quarter of AI’s recommendations weren’t in their own cellar. That mismatch is a predictable failure mode unless the assistant is given a precise, machine‑readable inventory or the restaurant integrates a real‑time stock feed. Without grounding, AI is guessing from general knowledge, not from the restaurant’s reality.
- Contextual hospitality cues: Human sommeliers read the room: mood, pacing, guest affinity, whether diners want to explore or be reassured. That social and service context often tilts recommended choices in ways AI cannot yet replicate, because the assistant lacks real‑time nonverbal cues and the deeper relationship memory that professional front‑of‑house teams develop.
- Hallucination and second‑choice drift: Asking for alternate options or second choices increased the AI’s error rate in the Cru test. Generative assistants may hallucinate realistic‑sounding but incorrect descriptors or misremember vintages and producers without explicit provenance—this is a core, well‑documented limitation across AI writing tools and specialized recommendation agents alike. Scientific testing of AI wine text generation has shown that models can produce polished tasting notes without ever having tasted the wine, which is useful for marketing but not authoritative tasting evidence.
The wines mentioned — quick verifications
Part of assessing the event’s credibility and the AI’s choices is checking whether the named wines are appropriate and commonly recommended for the dishes described.- Château Pontet‑Canet, Pauillac 2019 — a Bordeaux classified Fifth Growth in the 1855 classification; a robust, structured red that pairs well with rich beef and peppercorn sauces. The choice aligns with classic pairing logic.
- Tempier “Lulu & Lucien” Bandol Rouge 2022 — Bandol is a Mourvèdre‑forward Provence appellation; the Tempier cuvée referenced (Lulu & Lucien) reflects a high‑quality Bandol that typically matches richer pork or game dishes. The wine’s profile (Mourvèdre backbone, savory spice) can work with Iberico pork.
- Shafer Relentless Syrah 2021 — a Napa Syrah known for power and spice; a credible choice for mushroom and pepper spice contexts but often denser and more New‑World in style than Old‑World Bordeaux. It’s a legitimate option for a beef entrée, though stylistically different from Pauillac.
- Edelzwicker 2022 (Alsace blend) — a general Alsace blended white (Edelzwicker) that is frequently straightforward, food‑friendly and can work with spicy or wasabi‑accented seafood when selected for freshness. Edelzwicker is a recognized Alsace category and pairing option.
- Clos du Papillon 2019 (Loire white) — Clos du Papillon wines (from Savennières/Loire producers) are Chenin Blanc expressions that can work beautifully with cheese courses; a classic Loire Chenin pairs well with richer or goat‑style cheeses. The Clos du Papillon single‑vineyard cuvées exist and are respected Loire whites from producers such as Domaine des Baumard and Domaine du Closel.
What this means for restaurants and sommeliers
The human angle remains central
Guest feedback at Cru Uncorked made a clear point: many diners use AI tools informally when a sommelier isn’t available, but they still prefer human interaction when possible. Conversation, explanation, storytelling and on‑the‑spot substitutions remain core to the dining experience. Human sommeliers add value not just through selection but through curation, education and servicecraft. Cru’s own team echoed this, and industry coverage echoed the sentiment: AI is an augmentation tool, not an existential replacement.Practical uses for AI in beverage programs
- Menu drafting: Use AI to propose pairings during menu development as a quick ideation engine.
- Staff training: AI can generate tasting notes, flashcards and quiz content for new servers and sommeliers.
- Substitute suggestions: When inventory runs low, an AI informed by a live stock list can recommend acceptable swaps quickly.
- Customer tools: Chatbots and QR‑driven assistants can help guests who want a DIY pairing when the dining room is busy.
Important caveats before integrating AI
- Ground the model. Feed a validated inventory and price list into any assistant used for front‑of‑house pairing to avoid recommending unavailable bottles.
- Keep a human in the loop. All AI pairing suggestions should be reviewed by a beverage professional before being offered to guests.
- Audit outputs. Periodically test the assistant with blind checks and real diners to measure alignment with guest preferences and to catch drift or hallucination.
- Account for experience value. Pairing is a service; guests who pay for a sommelier expect conversation and discovery, which AI alone cannot fully supply.
How to pilot an AI pairing program — a step‑by‑step playbook
- Define scope: start with a single menu or service shift (e.g., lunch only) and a single assistant (Copilot, private LLM or a wine‑specific RAG setup).
- Inventory integration: export a CSV of cellar items — producer, vintage, bottle price, floor price, and current stock — and feed it through a secure retrieval layer so the assistant sees what you actually own.
- Prompt engineering: craft prompts that include explicit constraints: course description, spice levels, price band, region preferences and whether the guest wants familiar versus adventurous.
- Blind testing: run internal blind tastings where guests vote on AI picks vs. sommelier picks; record outcomes and take qualitative notes.
- Operationalize: if the test performs, integrate the assistant into POS/ordering flow or a sommelier’s tablet as a “first‑pass” tool, keeping the sommelier as final authority.
- Governance and audit: log every AI‑suggested pairing, track guest satisfaction, and periodically retrain or reconfigure the retrieval layer to align with cellar rotations.
Broader industry context: where AI already helps—and where it’s hype
AI has legitimate use cases across the wine value chain: precision viticulture, fermentation control, inventory forecasting, consumer personalization and label recognition. Industry analyses and industry experiments show AI can approximate human‑level descriptive text and make sensible pairing suggestions when anchored to empirical data. But the technology cannot taste and tends to synthesize human descriptors into fluent prose; that is powerful for discovery, but it is not the same as sensory judgment. Experimental and academic reporting has demonstrated that AI‑generated tasting notes can be indistinguishable from human writing — which is both a strength (scalability) and a weakness (no first‑hand tasting evidence).This means restaurants must evaluate AI not as an oracle but as a productivity tool that augments staff. When used with discipline, AI reduces mundane overhead (menu mapping, alternate selection generation) and frees sommeliers for higher‑value guest interactions.
Risks and long‑term implications
- Commoditization risk: If AI-generated pairings become ubiquitous and uncurated, the differentiating craft of a restaurant’s beverage program could erode; guests might expect “AI recommended” as baseline and not pay for curated expertise.
- Dependence and de‑skilling: Overreliance on AI for first choices can atrophy a team’s wine‑matching instincts if training and review are not enforced.
- Hallucination liability: Incorrect vintages, misattributed producers or recommendations for unavailable or counterfeit bottles can cause real service failures and reputational harm. Restaurants should treat AI outputs as drafts, not decisions.
- Data privacy/contracting: If an AI service ingests proprietary menu engineering or guest preference data, venues must understand how vendor platforms use that data; contractual clauses should protect commercially sensitive inputs.
Bottom line: augmentation, not elimination
Cru Uncorked’s experiment is revealing because it is pragmatic: a lively, guest‑facing test that shows how an AI assistant can both surprise and conform. Copilot’s winning Bordeaux pairing demonstrates the assistant’s strength at surfacing crowd‑pleasing, classic matches; the sommeliers’ narrow overall victory and the guests’ preference for human conversation underline the irreplaceable value of service, storytelling and on‑site expertise.AI in the wine room looks much like it does elsewhere in hospitality: it is a force multiplier when properly constrained and supervised, and a source of risk if used as an unsupervised decision engine. Restaurants that want to benefit should start small, ground their models in current inventory, and preserve human judgment as the final step.
Practical next steps for restaurateurs and beverage directors
- Audit your wine list and export a machine‑readable inventory (CSV or database) as the single source of truth.
- Run a short pilot: choose two weekly service nights and run AI suggestions on a tablet for the sommelier to accept/reject.
- Keep a log of guest votes and qualitative feedback; measure NPS and re‑run blind tastings quarterly.
- Train your team on AI failure modes and prompt hygiene; make “Check inventory” a mandatory AI handshake.
- Treat AI as an assistant: it drafts, humans finalize, guests receive the story.
Cru Uncorked’s Sommelier Showdown is not a last stand for sommeliers — it’s a case study in pragmatic co‑operation between craft and code. AI offers speed, scale and a keen recall of canonical pairing logic; human sommeliers bring nuance, inventory awareness and the relational craft that makes dining memorable. The future of beverage service will be judged not by whether a machine can propose the “right” bottle on paper, but by whether technology helps hospitality teams do what humans do best: make patrons feel known, served and delighted.
