The Problem

Premium wine bars face a critical bottleneck: staff wine knowledge. Training sommeliers takes 2+ years and costs $50K+ per employee. Result? Missed upsell opportunities, inconsistent recommendations, and frustrated customers.

The average wine bar loses $30K annually from poor pairings and staff turnover. Customers spend less when servers can't confidently recommend wines.

The Solution

I built VineAI, an AI sommelier that combines natural language understanding with wine expertise to deliver personalized recommendations in real-time.

Technical Architecture

  • Gemini 1.5 Pro for natural language understanding and conversational flow
  • RAG pipeline with Pinecone vector DB containing 10K+ wine profiles
  • FastAPI backend with sub-300ms response time
  • Next.js customer interface with real-time recommendations
  • Square POS integration for dynamic pricing and inventory

The Results

Technical Deep Dive

RAG Pipeline Architecture

The core innovation is a Retrieval-Augmented Generation pipeline that combines vector similarity search with LLM reasoning:


# User Input Processing
user_query = "I'm eating grilled salmon, budget $40"
embedding = embed(user_query)  # Convert to vector

# Vector Search
similar_wines = pinecone.query(
    vector=embedding,
    top_k=5,
    filter={"price": {"$lte": 40}}
)

# LLM Reasoning
recommendation = gemini.generate(
    prompt=f"""
    Customer: {user_query}
    Matching wines: {similar_wines}
    
    Provide personalized recommendation with:
    1. Best match wine with reasoning
    2. Tasting notes
    3. Why it pairs with salmon
    """,
    temperature=0.7
)
                  

Performance Optimization

  • Caching layer: Redis for frequently requested pairings (90% cache hit rate)
  • Embedding pre-computation: Wine profiles vectorized nightly
  • Batch processing: Multi-table recommendations in single API call
  • Edge deployment: Vercel Edge Functions for <100ms latency
