Infused?
You will be.
Immerse one of these little devils in cold water for six minutes, give it a quick stir and, voilà, a pint of foaming beer (3.8% ABV).
The sachets contain freeze-dried triple-fermented hop concentrate, gypsum and a CO2/nitrogen-based foaming agent.
Also available: German Lager, Irish Stout, Old North Country Ale and Middle Earth Mead.
