Query: Grapevine: A Wine Prediction Algorithm Using Multi-dimensional
  Clustering Methods   We present a method for a wine recommendation system that employs
multidimensional clustering and unsupervised learning methods. Our algorithm
first performs clustering on a large corpus of wine reviews. It then uses the
resulting wine clusters as an approximation of the most common flavor palates,
recommending a user a wine by optimizing over a price-quality ratio within
clusters that they demonstrated a preference for.
