#16 - Coopers Ginger Beer [Kit]

First brew of 2012! At one of my previous beer tastings, one of my friends (who is also a brewer), brought a few samples of a coopers ginger beer that he made. Needless to say it was the hit of the night and everybody loved the taste including my girlfriend who kept going on about it and wondering when my friend was going to bring more over again. Naturally this was prime opportunity for a Christmas present and her first brewing opportunity. :)
Coopers Ginger Beer
Sure enough I got it for her along with 500g of extra light and 500g of light spray malt. Along with the contents of the can, this would bring the alcohol content of the beer to between 3 and 3.5% which should lead to a light and refreshing brew. 

Making the brew was not much different from that of a normal kit except for the fact that less water is needed. The kit is mixed with 2 litres of boiling water and then mixed with the malt extract. It is then topped up to 19 litres compared to the conventional 23 litres as is common with other kits. 


It is now in the fermenter with an OG of 1032, which is a little on the low side and will probably result in a final gravity of 1010 giving just under 3% alcohol. When carbonating the sugar might add on another 0.25 to 0.5%. The instructions on the back recommend using 1kg of raw sugar which would have a higher fermentability than malt extract at the expense of body. If making the kit again I would make it with the raw sugar and compare against the malt extract to see which gives the better flavour.

#15 - Ronk Christmas Bock [Extract]

Since its getting close to the festive season I went searching for a Christmas beer that sounded tasty. Seeing as I was still quite new to extract brewing and I had just started using BeerSmith (#14), I went looking on their website for a recipe. I went through the various recipies and came across "Happy Holidays Ale" which attracted my attention due to the simplicity of the ingredients and the addition of a speciality grain called 'Special B Malt'. It was great to see something that wasn't the same old iteration involving crystal grains.
Steeping grains
As was the case in the previous brew (#14), some of the ingredients were not available in the home brew store. I had to substitute the grains with something so I literally guessed that Carafa Special I Roasted Caramalt would do the trick. 

The resulting taste of this brew has been very good. Fairly good head retention which I reckon could be improved a lot with the addition of some flaked Oates. As it was a Christmas beer I would have liked a bit more of the cloves and cinnamon to come through. They were very much in the background and I couldn't detect them. The next time I think I would double their addition size to increase their potency. The hops come through very well in aroma and taste. They are not overpowering but are still upfront enough to be enjoyable. Overall a recommended recipe. :)

#14 - 60 Minute IPA (Continually Hopped) [Extract]

Ingredients for first extract recipe
After brewing with kits and experiments I finally moved up the ladder to extract brewing. I purchased a small 4 gallon stock pot and finally got round to using BeerSmith to its potential! My first brew was initially meant to be a Dogfish Head 60 Minute IPA clone based on this recipe but none of the Irish home brew stores had all the hops so I had to substitute. I think most hops were substituted quite well other than the Amarillo Hops which seem to be quite unique. I also had to get a slightly different type of grain (Crystal 60L) for the same reason as the hops. I'm thinking that with the amount of substitutions it is no longer a clone. :)


Steeping the grains, Crystal 

Initially I brought the water up to 65 degrees and put 
in the grains to steep for around 20 minutes. As my stove is so slow to heat the water, I was able to turn it down to the lowest output and that kept the temperature relatively constant. The colour change from a couple of minutes of steeping the grains can be seen in the adjacent image. 

After steeping, I removed the grains and didn't sparge them although I have read in several places that you should, so I might do that the next time. I then brought the water to a boil which took AGES due to the poor cooker. The length of time that it takes to bring it to a rolling boil really made me understand while all the yanks are using propane burners or huge elements in their kettles. It really is a time saver to have a decent source of heat.  

Once boiling, the endurance test began. The recipe calls for the wort to be continuously hopped for the full 60 minutes. I had two timers going, one for the total 60 minutes and the other which went off every minute to signal a hop addition. The idea behind this is to add a few pellets/cones every minute so that you end up spreading out the whole lot over 60 minutes. I was extremely paranoid about a boil-over so I had 2 tea towels ready to grab the handles and take it off the head at the first signs of boiling over. Thankfully the boil-over never really happened, probably due to the length of time it takes for the cooker to bring the wort to the boil.  


Once the 60 minutes had elapsed, I took the pot off the head and lowered the pot into a sink of cold water. I then ran down to my local store and got 2 bags of ice which I then dumped into the pot. The ice is surprisingly effective at getting the wort down to pitching temperatures. I have seen arguments about putting ice about whether it is a good idea or not but it is safe to assume that the ice is completely sterile as otherwise people would be getting sick when consuming it with their drinks.

High Krausen!
It took about 5 minutes for the wort to cool once the ice was added so I then transferred it to a freshly sanitised fermenter through a couple of sieves. There was a lot of debris in the wort due to the large amount of pellet and whole hops so the sieves got clogged repeatedly. I topped up the fermenter to the 19L mark with cold tap water and pitched the yeast. I had previously made a 1L starter with a sachet of Safale US-05 and some malt extract. Due to my experience of using kits I wasn't familiar with the necessity of using a blow-off tube.....It was necessary this time.....for several days in fact! Part of the problem was due to the fact that the capacity of the fermenter was only 23L (as opposed to the normal 30L) so the head-space was quickly filled with Krausen. It is due to reactions like this that I have added this  brewing t shirt  to my Christmas list. :)

#12 - Brewers Choice Traditional IPA [Extract]

Since my original coopers IPA in brew #3 had completely run out I decided it was time for another IPA. I so impressed with the process of making the Weissbier in brew #11 that I went with another Brewers Choice kit. When making kits you never have any experience of steeping grains (at least not initially) but this IPA had several types of grains to be steeped and a couple of types of hops. They were all contained in their own tea bag things but you could smell that "IPA smell" from one of the grain bags and I was really impressed with that. I didn't realise that certain types of grain could have such an affect on the taste.

Please excuse the apparent filth of the cooker but it was rusting before I moved in here. :P  I have the grains and hops steeping in a pot of boiled water which is sitting on a wooden board to keep in some of the heat. This steeping is done 3 times. The coopers malt extract is also heating up in the back along with a Alexander's Pale Kicker which I later dumped as it was old and smelt disgusting.

When bottling the brew I used dextrose for the fist time without a bottling bucket. If there is one method that makes the misery of bottling worse then this has to be it. It was an awful mess, when adding the dextrose to the beer, it foamed out of the bottles. When adding the dextrose first it then foamed meaning it took twice as long as it required waiting till the foam died down. I was also conservative with the amount I put in with slightly less than 1 teaspoon. I opened a bottle earlier in the week and it wasn't carbonated yet which has quelled my previous worry that the whole batch would start exploding. : /

I will update this as the picture changes.

#6 - Coopers European Lager [Kit]

I tried this brew as I was looking to make some kind of light beer that didn't need the lime slice like brew#1 and wasn't as heavy as brews #3 or #5. I didn't like how mainstream it looked (I'm the type that judges a book by its cover) but I was willing to give it a chance. I made the brew at one of my beer tasting sessions with a load of friends. They were all curious to see the process so it made sense.
There was nothing out of the ordinary to report during the fermentation process of this beer.Although there was plenty to talk about from the bottling stage. I had previously primed all my bottles with 1 carbonation drop each while being aware that 1 drop is actually suited to 330ml bottles. For this batch I chopped a load of drops in half and put 1.5 drops into each bottle thinking it would be fine. It was fine.....kinda.... The beer was definitely over carbonated in the end which I didn't expect. I genuinely thought I was putting the perfect amount of sugar in and I had read in several places of others doing the same with positive results.

Instead I noticed that there had been "seepage" on some of the Grolsch bottles that I had stored the beer in. The pressure had obviously built up to such a degree that it had vented out through the swing top. I found this worrying and interesting at the same time. I did some searching around and found that it was indeed rare for Grolsch bottles to explode and this 'self venting' feature commonly noticed. I enjoy the 'POP' when opening a normal Grolsch bottle but opening the ones containing the lager was unbelievable. It was shocking how loud it was, it makes a room full of people go quiet!  :)  

I did let it age for much longer than I normally had done for previous beers.This was partly due to fear that a bottle would explode in my face if I disturbed it.  I was pleasantly surprised by the taste which was very refreshing and a little sweet which was a good thing. I don't know if I would bother brewing another Lager as I don't have any space or equipment to store it in cool temperatures for several weeks. I would probably make a pale ale instead.
