The inventor is Dennis Neven, explaining the name "Dennisje".
After a minimum consumption of three glasses one is supposed to be drunk.
Can you fill me up on the whiskey, i'm gonna take a dennisje.
The drink has its origin in the nightlife in Lloret de Mar, Spain and since then has spread all across Europe.
Every brand of whiskey is suitable as long as it contains 40% alcohol.
*Adding coke/energy drink isn't necessary but it makes it easier to consume large amounts of booze.
Go easy on the coke, you need the room in your glass for your whiskey to create a dennisje
