As I mentioned in the previous post, hopefully The Grove will be showcasing a 'Randalled' beer during Thursday's IPA day. But what is it? This is what I believe from what I have been told and what I have picked up off the web. If I am wrong I apologise in advance.
To Randall a beer is essentially a way of dry hopping a beer between the cask and the bar. The idea was initiated in 2002 by 'Dogfish Head', an American brewery to make one of their beers even more hoppy at the point of sale. It comprised a water filter filled with hops and the beer was drawn through the filter between the cask and the pump, giving a massive hit of fresh hops.
The system was slightly amended during the next ten years and they are on sale commercially for around $400. Not only hops can be used, anything can be put in the Randall to flavour the beer, from coffee beans to Jalapeno peppers or oak chips soaked in Bourbon!
If you do not have a few hundred dollars lying about then it seems that they can be improvised by using transparent water filters and a stainless steel filter bed.
Now you know some of the science, get up The Grove tomorrow and see it in action.
