Thou shalt be generous but not pushy
Generosity of spirit and rare beer can help receive the keys to the kingdom, but be not overly pushy. For while some might rejoice at the prospect of receiving unto him a taste of last year's KBS, the guy who explicitly hates stout could find your evangelical insistence off-putting. Plus, waste not KBS, want not KBS, for there is a special sub-circle in hell for doing such.
Thou shalt not gloat
Let not your experience become your sole claim to fame. Your pilgrimage to Belgium should not dominate your conversations, nor should your RateBeer screen name be referenced in casual conversation. Speaking at length about your cellar does nothing for anybody without access to it. For thy cellar is actually a closet, and thy boastfulness is thy downfall.
Thou shalt respect the ABV
Those who rush to consume in quantity without regard to impact are forever doomed to explain increasingly lewd text messages to exes the next day.
