Brewday: Playoffs Rye IPA take 4

First hop addition, 60 of 340g
A disproportionate number of my brews are American IPAs and Pale Ales - 22 out of my last 67 brews. I love a wide range of styles but it's harder to get a good, fresh IPA than most other things so I need to brew these more often to get my fix. One thing I don't think many people, even plenty of beer geeks, grasp properly is just how quickly beer deteriorates, hoppy beer in particular. Freshness is hugely important for most styles of beer. For a bit of an insight into what I mean, Literature and Libation has a great writeup of the experience of tasting the same IPA at 5 days and 90 days old.

The huge distance that most beer has to travel is something we have working against us in Australia. Our population is so spread out that beers have to travel a long way before they get to the majority of consumers. I've had way too many IPAs and pale ales with little to no discernible hop aroma. A bottle might be a month within its best before date but still be long past its actual best. In my dream world everyone has at least one brewpub within walking distance of their house and the beer is always fresh.

In this respect home brewers have a serious advantage over other craft beer consumers. No one gets to drink beer that's more fresh. For brewers who can brew to a decent standard, that means that the beer in their own homes is often better than the majority of commercially available beer. Avoiding the travelling distance and having control over storage makes a particularly big difference for IPAs and other modern hoppy beers. You're also always aware of how old the beer itself is and how soon it needs to be consumed.

All that is really just to say I'm excited about brewing my Playoffs IPA again and having some fresh IPA action. It should be ready just in time for this year's NBA playoffs which are looking like they'll be fun, especially in the West. This is my 4th crack at this particular beer. The first one I loved, the second I had a couple of enforced changes and was disappointed, the third was in late 2013 and was just ok. It suffered due to my rushed production and the aroma was not impressive. It was there but the current batch of Columbus is more potent than what I was using back in 2012 so it dominated in a way that wasn't what I was after and the overall aroma and flavour was a bit muddled and didn't 'pop' like it should have. This time I decided to make some changes to my process and the recipe to hopefully improve things.

Probably the biggest change is with the hops because I felt like going with something different this time. I may return to the original hop varieties eventually but this time I wanted to make use of the opportunity to try new combinations. I've switched out the Amarillo and Columbus of the original recipe and added in Centennial and Ahtanum. The ratios are a bit different as well, I've gone for 2:1:1 Centennial:Citra:Ahtanum throughout and added an extra dose of hops for a 50 minute sub-80C steep. The aroma as I transferred the wort into the fermenter fully justified the decision - it was incredible.

One of the pieces of feedback I received last time around was that the rye that was advertised didn't really come through so I've increased it to 20% of the grist compared to the original 14%. I also went with the Joe White Traditional Ale malt that I used originally instead of the pilsner malt of my last attempt. It was partly a decision to increase the colour and partly to avoid burning through my pilsner malt before I can get a re-up through a bulk buy.

The process changes are relatively small but will hopefully improve the finished product a little. I've been reading a bit about mash and post fermentation pH and it seems that a lower pH will help the hops to come across with more clarity. With that in mind I've aimed for a mash pH of 5.3 rather than the normal 5.45 I've usually been after. All this is theoretical though since I'm working with estimates off a spreadsheet rather than actual pH readings. All I can say for sure is that the pH is lower this time than when I've brewed it before. I'm considering buying a pH meter so I've got a better idea of what's going on with my mash and post fermentation pH levels.

I've also decided to start experimenting a bit with chloride:sulphate ratios. My normal practice with hoppy beers is to add a decent amount calcium sulphate and a small amount of calcium chloride. This time I'm keeping the sulphate addition in my normal range but I'm pushing the chloride a bit higher to see how it alters my perception of the beer. It's just something I haven't really experimented with at all up to this point and I've been wondering about it so I thought I'd make the change.

So with all that decision making out of the way, the brew itself should have been pretty straight forward but I ran into a couple of problems. The big one was that when I emptied my urn I found that part of the element had blackened. I've had that happen once before and that beer had rye in it as well so I'm guessing that's something to watch out for when using that grain. Fortunately the wort itself smelled and tasted great so I'm hoping that I got away with nothing more than a fair bit of scrubbing to remove the cooked on stuff. The other problem was small but annoying. I missed my gravity target even though I already aimed lower than normal in my recipe design (75% instead of my normal 80%). 1.061 instead of 1.062 isn't a big deal but poor efficiency was the reason I stopped using Joe White malt in the past and this result isn't a strong motivator for me to buy more. I think I need to alter the extract potential in my brewing software to compensate for that because it's obviously yielding less than its specs say. Those problems aside, the aroma of the wort was fantastic and if the finished beer has a similar character I'll be very happy.

Brewday: Hansard's Delight Red IPA

My friend Luke enjoyed the Shepherd's Delight Red IPA, a Little Creatures Single Batch released sometime in 2013. He has a hunger for hoppy beers and asked me if I could brew a Red IPA. I said 'sure' and whipped up a recipe. That was at least 6 months ago and I never got around to brewing it. So I'm trying to mend my ways with my first brew for 2014.

The idea for this one is a deep red colour leaning towards black. People on the AHB forum recommend a combination of 5% CaraAroma and 1% Roast Barley to achieve a red colour so I went with that and made up the remaining 94% with Golden Promise and some munich malt. This was a chance to focus on presentation both in terms of colour and clarity so I hope it comes out with something that can be legitimately called red, not brown. The results during the brew looked promising.

For hops I went with a modest first wort hop addition and then added a heap of Galaxy and Centennial at the end of the boil for a hit of passionfruit, citrus and floral hops. Then there was another heavy dose of Centennial alongside Columbus for the dry hopping. I went for bitterness on the high end of the IPA scale (it's got an estimated 70 IBUs) to give it a decent bitter kick with the high level of malt flavour.

This was Luke's first experience of the brewing process from start to finish and it was fun to introduce him to the process behind the beer he drinks.

Birthday Brew #3: Playoffs Rye IPA

This is the last of the 7 straight brews for the wedding and birthday! It's been a huge project for me with the planning, preparation during each week, the brewing and bottling. More than that, it's been great sharing the fun of brewing with friends and having their help with the physical side of brewing. I couldn't have done it without them.

The Playoffs Rye IPA had its beginnings in the month before the 2012 NBA playoffs when I realised that I'd need some very American beer to drink while watching basketball. There were some brilliant series along the way with LeBron James and the Miami Heat crushing OKC in the finals. The Playoffs Rye IPA was exactly what I wanted to go along with that. It was by far the best beer I'd brewed to that point and I was crushed when it ran out. I tried to brew it again later in 2012 but due to a couple of ingredient changes that were forced on me it ended up being a big disappointment. This brew is a chance for vindication and will hopefully go nicely with smokey pork ribs and pulled pork.

It's interesting to see how much has changed since I brewed this one the first time. At that stage I was brewing 1/2 size batches on the kitchen stove, I wasn't altering mash pH or water chemistry, I didn't always pitch enough yeast, I didn't have fermentation temperature control or the ability to oxygenate wort. It's great to be able to look back and see the improvements I've been able to make to my process over 18 months or so. The only recipe difference between this version and the first is that I used pilsner malt instead of Golden Promise to keep the malt flavour out of the way of the rye and hops. I debated raising the rye malt percentage to around 20% but in the end I decided to keep it the same as the first time around.

Huw and Will both came around to help me brew this one and it was awesome. They've both been around for several brews and they know the process well enough to be able to manage it on their own and help me to conserve energy. I've reached head brewer status!

Birthday Brew #2: Nelson Sauvin Pale Ale

Obligatory hydrometer shot
The original extract version of this beer was one of my early brews in 2010. At the time I didn't know that different hops could have different levels of bitterness let alone what alpha acids were. For about 7 or 8 batches I brewed the same pale ale with different varieties of hops. The first 5 or so worked well because the hops all had an AA% fairly close to the original recipe, the 2 after that I used Saaz and East Kent Golding. They didn't give anywhere near enough bitterness but it did force me to work out what was going on.

Nelson Sauvin was a revelation. That crazy fruity aroma climbed out as soon as the bottle was opened. So fresh and bold. Of course there were plenty of commercial hoppy beers around but there weren't many highly hopped beers brewed in Tasmania and the hoppy beers from outside the state tend to lack something in the freshness department. Now I take the freshness of home brew for granted but it was so exciting back then.

The spine of the recipe is essentially the same as the wedding pale ale except that the gravity was increased slightly and the Crackerjack biscuit malt in the wedding beer was replaced with Victory in this one. The hopping rate is similar to the original extract recipe with the dry hops increased a bit.
