Auckland Beer Festival!



     It’s been a little over three months since we seriously decided to take our home brewing endeavors to the next level and become true professionals.  Alan Knight already works as the Master Brewer at Wild on Waiheke where he makes damn fine beer.


  (and has done for the last fifteen odd years), but for the rest of us, who have only ever seen our beer consumed and enjoyed by our nearest and dearest, it’s all very exciting.

     There are a lot of hoops one has to jump through to actually get set up as a brewery. We talked to the Auckland Council, but they seemed not to really know what a brewery really was or what it did. They had regulations for brothels (which are legal here) and undertakers, kitchens and jam makers, but not for breweries. So we did everything they asked us to do despite the fact that they were treating us as “food preparation”  and clearly had no idea what we should actually be doing, which is odd when you consider that New Zealand has around 60 microbreweries so this can’t be the first time it has come up.

      I know for a  fact that any brewery would be a lot more sterile than required under the Food Hygiene Act (they have guidelines for the acceptable level of rat faeces in food - when making beer than you can’t allow any). It would become infected and utterly undrinkable, but I digress.

     We went and talked to customs who wanted to sight a scarily gargantuan bond but who were happy for us to proceed. 

     And so, if all goes according to plan, The Ale Brewing Chaps, as we shall now be known, will make our debut appearance at The Auckland Beer Festival 2013

Here’s what happened last year




Yeah. Shit got crazy.

The Lucky 7


     The brewery was primed and ready to go. And we had the perfect recipe to test the apparatus. The 7: designed by engineer and brewer Jerry Wayne to reflect the characteristics of the Lotus 7, light, fun and fast (fast drinking that is).

Vrrrrooooooom!





     I was always going to be a late arrival to the brewery on that particular Sunday, owing to the necessity of taking my puppy to her training classes. Does anyone remember that tiny sock-looking thing I posted a picture of a while back? Well, she's now absolutely monstrously enormous.

 
Here she is sleeping in a puppy heap with Alan and Jen's dog Charlie. Awwww.

     So when I got to the brewery it was complete choas already and I hadn't had a chance to get a handle on how it had got that way. My first impression was just SUCH a lot going on. The two big 500L kettles outside were humming away, busy getting up to temperature for the mash in, grain was being milled, people were everywhere, eating pies, and curries and yelling and laughing. A lovely young couple were testing their homebrewing skills making some Kölsch for their wedding (which now I think about it is coming up very soon! Congrats Kat and Neil).

     Then came the mash in. With the expert guidance of Ben Middlemiss and Alan Knight we got all the grain for the 350L test batch of 7 mashed in with the tiny rouser from the 50L home brew system. The melanoidin malt gave the converting wort in the tun the most gorgeous orange glow. Photographs sadly do not do it justice, so I will let you use your imagination.

     Things seemed to be going so well. But we knew better than to relax. The 7 wouldn't be safe until it was safely tucked into its lovingly prepared 450L fermenter.

     Conversion took place, and a negative starch test gave us the green light to begin sparging and runoff to the kettles. The boil proceeded well, and 7 glorious hop additions lent their fragrance to the air.

And then.

     It was time to test the hop-back, the pipework and crucially, the heat exchanger.

     The thing about making beer is that once you finish boiling and adding hops, you really do need to get it from almost boiling to around 18°C as quickly as possible. You see, while the wort is boiling it's arse off, it is busy-busy producing a rather nasty chemical called dimethyl sulfide. When it's boiling, it's not a problem because it gets evaporated off, but as soon as the boil stops, the wort is sitting at a dangerous temperature. That at which DMS can form, but not dissipate. The result is that it sits in suspension and makes the finished beer taste and smell like rotting tinned corn.

     We were all very keen to get the wort through the 88 plate industrial heat exchanger as soon as possible. And that's when we hit a snag. 

The hop-back blocked, and the heat exchanged jammed full of hop particles.

About 50L of 7 wort went all over the floor.


 So the floor was very, very wet.


      Luckily, the lovely homebrewers had finished using the tiny heat exchanger. Er... yes. The very small one that we normally use for the 50L system. It was going to be a very slow and nerve-wracking run-off.

Finally, we got the remaining 300L of 7 into the fermenter.


     Then, the clean-up. Since I am the smallest brewer on staff I was nominated to climb in and dig out the mash tun. Luckily I had Alex and Tim to help me.




     The next day, a domestic air-conditioning unit was positioned in front of the fermenter to keep the wort at correct fermentation temperature. 

And eventually the wort finished fermenting. We ran off samples, we tested gravities, we tried the glorious elixir of gold it had become. We were ready to keg and condition.

     Let's just move this air-conditioning unit out of the way so we can get at the beer more easil-Fuuuuuuuuuuuuuuuuuuuuuuuuuck!
The air-conditioning unit over-balanced, the corner landing on the spigot, shearing it clean off.

    Beer was going everywhere. Alan, with reflexes born of long experience, stemmed the flow with both hands, while Alex and I dashed about finding any available vessels that could be sterilised and filled with 7 quickly. We ended up using pretty much every 30L fermenter in the place. It was coming so fast we probably lost another 20L to the brewery floor, so at least it has now been thoroughly christened. 


We reviewed our notes over a pint of what is now referred to as The Lucky 7. Hopefully our next brew will be much less eventful.

Happy brewing chaps!
