Mini project: Beer Infuser Research

I’ve just began working on a mini project, and have decided to post it online for you all to view. Transparency and all that jazz…

I’m facinated by the idea of infusing established beers with additional ingredients. The first time I came across such a scenario was none other than a BrewDog bar. The Edinburgh one to be specific. They have something called a Hop Cannon. You may have seen it.

It allows the bar staff to add ingredients to their beers, and feed the beer straight from the draft system. I tried out a hardcore IPA infused with short bread and oranges. It was pretty delicious. At the start of this year, I tried out a Santa Paws Scotch Ale with figs. Very sweet…

It’s a pretty cool piece of kit, and got me thinking about what is available on the consumer market. Doing a bit of research, I came across the Randall, a patented beer infuser to add your favorite ingredients to the beer.

What is a Randall?

A Randall is in technical terms an organoleptic hop transducer module. I barely understood this, so to some it up, a Randall is a filter that lets you connect a tap to you favorite beer and add additional ingredients to change the flavour of the beer. So you can add raspberries and salted caramel to your favorite stout, or double down on the hops in your pale ale.

It is a filter system that allows the user to run draft beer through a chamber that is topped up with your ingredients of choice (chocolates, hops, spices, fruits etc.) and the alcohol will soak up the flavors and add it to your beer.

The Randall by Dogfish Head

This invention was produced by Dogfish Head, a USA brewery that produce some pretty awesome beers.

Here is a breakdown of how it works:

  1. Beer enters the infusing chamber
  2. The automatic chamber vents eliminate vapor-locking and maximise contact with additional ingredients
  3. An adjustable faucet balances between different beer types
  4. Ice chamber keeps beer cold between pours

Again, this is also a pretty cool piece of kit. There was a brewery testing one out at the 2015 York beer festival. They seemed pleased with the results, but unfortunatley had ran out of beer just as I arrived. Maybe this year.

Other than that, I’m yet to see one up close and in action.

Similar items

There is of course other items that are out there on the market that do a similar job. The simplest and cheapest option being a standard french press.

Other items on the market exist mainly for spirits. In particular the Vodka Zinger, by Zing Anything appears to be quite an attractive piece of kit.

Vodka Zinger

It is a stainless steel bottle that has bottom-mounted grinder that retains the ground pulp of your ingredients, but allows the pure extracted flavors to travel through a fine-combed mesh screen and infuse the water. Sounds good doesn’t it. Probably would work with beer also! It is ergonomically very pleasing and looks like it would do the job. I’ll be testing it out a later date.

What I’m going to do

My plan is to experiment with these different types of infusers, and see what one delivers the best result. I’ll keep you posted on my activities, and share any worthwhile recipes if something doesn’t end up tasting like pish.

I’ll follow up with a post about this later next week.


Hopefully you found this short and sweet. I was in a bit of a rush to finish off the weekly blog posts, so excuse the all over the place nature of this post. I’m going to expand on this topic at a later date, but wanted to lay the foundations for the beer infuser and it’s current application for the beer market.

Cheers for reading!
