You know the feeling. You’re standing in the wine aisle, entirely confused. Hopelessly adrift on a an ocean of reds and whites. You’re anxious. You’re on your way to Tad and Jeanne’s house and you can’t bring the wrong wine-- not after the pleated jeans incident.
WHAT. WINE. SHOULD. I. BUY?

RETURN w.name AS NAME, t.name AS FLAVOR, r.weight AS HOW_BITTER
ORDER BY r.weight DESC LIMIT 8We’re asking Neo4j to find a pattern that moves up a hierarchy, insofar as we’re looking wines who belong to categories. These categories have specific flavor profiles, the severity of each of these flavor notes is carried in an integer on its relationship to that flavor called "weight." We then can ask Neo4j to tell us the top 8 wines found in the categories who have the strongest bitter quality.
That’s pretty neat, but I think we’re having fish-stick sandwiches, does a White Table Wine pair well with that?
match (w:Wine {name:'White Table Wine'})-[]-(c:Classification)-[:PAIRS_WITH]-(fishsticks:Food {name:'Light Fish'})
return w.name AS THIS_WINE, c.name AS IS_A, fishsticks.name AS WHICH_COMPLIMENTS_THISWe’re asking Neo4j to check if the node "White Table Wine" has a relationship labeled PAIRS_WITH associated with a node that has a name property "Light Fish". If Neo4j returns no matches we know that no, that wine does not pair with that food.
For example:
match (w:Wine {name:'White Table Wine'})-[]-(c:Classification)-[:PAIRS_WITH]-(fishsticks:Food {name:'Rich Fish'})
return w.name AS THIS_WINE, c.name AS IS_A, fishsticks.name AS WHICH_COMPLIMENTS_THISThe null table means that no, there is not a pairs with relationship between Rich Fish and White Table Wine. So crab and a dry white wine aren’t ideal.
identifying recommendations based on two flavors
Pretty cool…but you’re more into sweet, rich wine. Can we find what sorts of wines are most sweet and most fatty?
MATCH
a = (t:Flavor {name:'Fat'})-[:FLAVOR_FAMILY]-(n:Classification)-[:FLAVOR_FAMILY]-(tt:Flavor {name:'Sweet'}), (w:Wine)
WHERE (n:Classification)-[:CLASSIFIED_AS]-(w:Wine)
RETURN

ORDER BY SCORE DESC LIMIT 10
Neo4j is looks through the graph for the pattern highlighted in green, when that patten is identified it also checks if the "Wine Category" node has a relationship with a node that carries the label "Wine." We ask it using the REDUCE command to sum the integers carried in the relationship property named "weight". We ask for 10 DISTINCT results ordered by the most weight (the highest total values of our desired wine flavors).
