I hate

DG Jamaican Ginger Beer is the mack. All others are merely pale imitators, and a disgrace to the name. It's the mutts with Sailor Jerry.

Ginger cordial is also shit hot, w/ sparkling spring water.

I'll give you ginger cordial.
but those little DG cans... they're too sweet and it's only the initial cold fizzyness that does the trick which you can surely get with any can? even a can of ribena probably works.
