Pour me a drink, will you? The Challenge

I am thirsty and need a drink, but I don't know what to order. Your task is to provide me with either a drink or options for one.

I/O

Input will be either a base or a drink name.

If given a base, your program should output one random drink from a list of drinks with that base.
If given a drink name, your program should output the base that drink is made from.

Below is a list of drink names, ordered by their bases:

Absinthe:
    Death in the Afternoon
    Earthquake
    Green Russians
    Green Vesper
    Moloko Plus

Beer: 
    Black and Tan
    Black Velvet
    Boilermaker
    Michelada
    Irish Car Bomb

Brandy:
    B&amp;B
    Brandy Alexander
    French Connection
    Horse's Neck
    Sidecar

Cachaça:
    Caipirinha
    Leite de Onça
    Quentão
    Rabo-de-Galo
    Royce

Gin:
    Bramble
    Casino
    Clover Club Cocktail
    Gin Fizz
    Martini

Rum:
    Bacardi
    Cuba Libre
    Daiquiri
    El Presidente
    Piña Colada

Tequila:
    El Toro Loco
    Margarita
    Matador
    Paloma
    Tequila Sunrise

Vodka:
    Black Russian
    Bloody Mary
    Cosmopolitan
    Kamikaze
    Screwdriver

Whiskey:
    Bourbon Lancer
    Irish Coffee
    Manhattan
    Rusty Nail
    Whiskey Sour


Rules:


Standard Loopholes are forbidden.
If given a base, the program's output should be non-deterministic, meaning that multiple runs should result in different outputs.
Accordingly, when given a drink name, the program's output should be deterministic, yielding the same result for drinks with the same base.
You may assume the input will always be one of the bases or drink names in the list compiled above.
You may choose to print characters such as ç, ñ and ã as c, n and a, respectively.
You may accept I/O in any reasonable format.
This is a code-golf challenge, so the shortest answer (in bytes) wins.

Likewise, the input can be any of the drink names in the output column. If so, the output should be the corresponding base.

Yeah, naive approach. I tried some compression methods, and this one seems to be the shortest.

-2 bytes thanks to HyperNeutrino.

EDIT: Bug fixed.
