Bring on the hops!
I'm proud to present my latest homemade brewing gadget, a Randall. Its full name is Randall The Enamel Animal, and is also known as an organoleptic hop transducer module. The contraption was first invented by the Dogfish Head Brewery. It has later been bought by many pubs serving their beers, all in the the U.S. unfortunately, but they are to my knowledge only used for special events.
I have never tried it myself, but it sure looks like I good idea. I love hops and what couldn't be better than having beer pushed through lots of delicious hops cones on the way to your glass? Yummy!
As far as I know there are no places in Europe where one can try it. So, what was there to do other than to make one myself?
The device is made from one filter canister housing with threaded barbed fittings on both sides. Inside the filter there is a stainless steel pipe with twenty small 1.5 mm drilled holes. I had to get hold of and adapt this one myself. It wasn't easy as getting hold of a 1/2" stainless steel pipe was harder than expected. I ended up buying a towel rack from IKEA(!) and sawing it into pieces with a hack saw. Drilling the holes wasn't easy either as stainless steel is a pretty hard material. I ended up using five titanium covered HSS drills.
I have installed a dual system with two picnic faucets, so that one can serve the beer from the keg directly or from the Randall. That way it will be easy to find out what effect the hops have made to the beer.
The plan is to serve the keg of India Pale Ale through it at this year's Norwegian Homebrewers Festival. So, if you'd like to try it yourself you now know where to be on March 17th.
