BIAB#3 – Born To Be Mild

20130113-234259.jpg

I never thought I’d be interested in a beer called a “mild”. I like my beers to be the complete opposite of mild – clovey hefeweizens, hoppy American pale ales, roasty Imperial stouts. But I was interested to see an entire section for “Mild” recipes in Graham Wheelers book and started a bit of research.

Historically, the name “mild” referred to a beer which hadn’t been aged in vats and didn’t have a slightly sour tang. These days, mild generally means a beer with less bitterness than a regular English bitter or pale ale. They are generally low in gravity, easy to drink and have a restrained hop flavour with little or no aroma.

I wanted to squeeze another small all-grain batch in over the Christmas holidays and wanted to try something different so I decided on this recipe. The grain bill is pretty complex for a mild and I doubt you’ll find an English brewery putting so many different malts into their mild, but I wanted to add a little complexity, so in addition to the Maris Otter base I went for two different types of crystal, biscuit, black malt, torrified wheat and pale chocolate malt for colour and some coffee/roasty notes. The smell of the grains in the bucket was fantastic, even before I doughed in!

I followed the same procedure as my last two BIAB batches, using 11 litres of treated water to mash with, and using 4 litres for dunk-sparging. My efficiency worked out at 60% which is not very efficient at all, but at least it’s consistent. Most of the recipes in Wheelers book tend to have IBUs around 22 so that’s what I was shooting for here. Most of the recipes also seem to include Fuggles hops so I bittered with EKG and used my last remaining 7g of Fuggles as a flavour addition.

The colour of the wort is amazing – a deep mahogany colour. I’ll attempt to serve this with slightly less carbonation than usual. About 2 volumes should do it.

Notes

20/01/2013 – Bottled using 65g grams of table sugar and got 25 bottles. Great nutty smell from the fermenter. Cold crashed in the shed for two days before bottling.

01/03/2013 – First taste after almost 6 weeks in the bottle.

03/03/2013 – Scored 28 points in the 2013 NHC competition. I suspect this was judged in the wrong category. One of the judges described it as “a little mild”. The other judge wrote “Northern English Brown” on the scoresheet. Pretty respectable score considering the judges didn’t even know what it was they were supposed to be judging. In any case, I think it’s an excellent easy-drinker and I’d definitely do it again.

21/04/2013 – I’ve got about 2 bottles of this left and it was a real success – I don’t know why I never updated the notes on this. It could easily be described as a brown porter. It’s got a nice caramel, mocha quality. Fairly light body but an assertive bitterness that I wasn’t expecting from the paltry 22 IBUs.

PM#8 – “Pie-O-My” Amber Ale

20130101-231817.jpg

It’s New Year’s Day and I’ve already got two brews done for 2013! I was feeling very pleased with myself after getting my second BIAB bitter in the fermenter and I had a quiet house, so I decided to do a partial mash American ale. It was all very “spur of the moment”, both in the planning and the execution. I decided it was time for another stab at an American Amber Ale. My last attempt didn’t go so well due to missing my target OG by 4 points! As such, what should have been a luscious, caramelly beer turned out thin, overly bitter and weak in flavour. Perhaps I’m being too harsh on myself. It wasn’t too unpleasant to drink, but it took me a lot longer to get through the 19 litres than I expected.

So I’ve decided go for a slightly different style of amber/red this time. Instead of relying on dark crystal malts to give colour and flavour, I’m going to do a beer which is more typical of an American pale ale, but I’m going to use a small charge (70g) of pale chocolate malt to give a nice hue to the beer. I’ve not used pale chocolate malt before so I’m not sure whether what colour this is going be when it’s in the glass. Flavour-wise, I want a hint of roasty character, but not too much. I’m using a mix of light and medium crystal malts and a decent portion of biscuit malt. In my haste, I forgot to add something like CaraPils or wheat malt to aid head retention. My last few beers have included malts like these and I’ve been very pleased with the results. However, there is a full pound of crystal in this so I’m not expecting any issues with body or head retention.

I recently got my grubby mitts on some 2012 Amarillo and Centennial so generous additions of these hops will provide the flavour and aroma for this beer. I’ll use a small addition of Columbus for bittering. I’ll be shooting for 40 IBU and watching the AA rating on my hops closely this time.

01/01/2013 – My quiet house inevitably turned to chaos during the brew and the concentration started to lapse – I forgot the late addition of malt extract and only realised my error with one minute left in the boil. I had a choice – add the extract and boil for another 10 minutes (which would extract a lot more bitterness out of my high-alpha flavour hops) or add the extract at flameout and risk an infection with extract that isn’t fully sanitised. I decided to add the extract and keep it on the heat for a couple of minutes (it never came back up to boil). Adding the extract to boiling wort surely killed any nasties in there and I didn’t want an overly bitter beer.

I got an OG of 1.052 when topped up to just under the 20 litre mark. Pitch the dry yeast directly into the fermenter, as the brew day had been long enough at that point with the hassle of rehydrating yeast.

All in all, an unsatisfactory brew day. There’s nothing wrong with the recipe per se, but it wasn’t the recipe I actually wanted to do. My forgetting to add the late extract could have been partly due to the fact that my last two brews have been BIAB/AG and I haven’t needed to carry out this step. I think I’ve been bitten by the all-grain bug as the BIAB method I used just seemed really simple. A full-size boiler and the move to all-grain beckons it seems.

11/01/2013 – Dry-hopped with 60g of hops. I jammed the floating hop bag down to the bottom of the fermenter using a sanitised paddle. I think this might be my biggest dry-hop to date.

20/01/2013 – Bottled with 130g of table sugar. Got 33 bottles from the batch. Cold crashed in the shed for two days before bottling.

09/02/2013 – With only about three weeks in the bottle this is drinking extremely well. I wish I could say the same about my series of BIAB English bitters! The amber ale has a decent hop presence but really only reveals its charms when the beer warms up to “cellar temperature”. It’s like a scaled-down version of the Big Dawg Imperial Amber. It would be good to do a side-by-side comparison but I’m fast running out of bottles of the Big Dawg. I think the next amber ale I do will be following Jamil’s recommended 35 IBUs. The 40 IBU of this beer fights the caramel sweetness just a little too much. I was concerned about having no wheat malt or CaraPils in this beer. Out of habit really, I’ve been including it in most of my recent American ales, but the head formation and retention is great.

18/02/2013 – I think I’ve changed my mind about this. The last couple of bottles I’ve had have been quite bitter, astringent almost. I think the dry-hop might have been too much, even though it falls within the generally accepted guidelines for dry-hopping. It does seem very grassy. I’ll leave another couple of weeks before tasting.

20/02/2013 – I think I’ve figured out the problem with this beer. I think the astringency I’m tasting is actually just hop bitterness. I’ve been doing some reading up on the effects of hop steeping or flameout additions on IBUs. Some people calculate their IBUs using the final kettle addition at the 1-minute mark, even if the hops are only added at flameout. It seems to make sense. A lot of the podcasts I’ve listened to have commercial brewers telling us about the bittering contributions they get from whirlpool additions. As an experiment, I changed the two flameout additions specified in the recipe above (25g Amarillo, 25g Centennial) to 1 minute. The result? The IBUs shot up from 39 to 53!! You are definitely going to taste an extra 14 IBUs in a 1.052 beer with a moderate amount of crystal malt. I think I’ll definitely be doing some further experimentation with this. It seems that the last few pale ales I’ve brewed have been really over-bittered. I’d like to do some playing around with hop-bursting also, adding all of the hops in the last 15 minutes or so, with no traditional bittering addition at 60 minutes.

08/03/2013 – Definitely too bitter but the hop flavour in this is just lovely. Big-ass grapefruit from the Centennial. A decent American Amber Ale is still beyond my reach it seems! Next time I’ll be dropping the IBUs drastically and increasing the crystal malt by 50%.

BIAB#2 – Navy Pier Special Bitter

20121231-225306.jpg

Tight git that I am these days, I was determined to re-use the yeast slurry from my first BIAB effort, Tailgunner Best Bitter. This recipe is based on a clone recipe I found for the wonderful Goose Island Honkers Ale. So how does this recipe differ from my last special bitter? Well, I’ve left out the torrified wheat and will be using a much bigger amount of plain wheat malt. I’m expecting a significant flavour contribution from this as it’s not there simply for head retention. This is also a much hoppier beer, with three large additions of Fuggles. (Goose Island is reported to use all Styrian Goldings and Fuggles were the closest match I had available.)

Estimated Color: 10.9 SRM
Estimated IBU: 29.3 IBUs
Brewhouse Efficiency: 60.00 %

Ingredients

2.600 kg Pale Malt, Maris Otter (3.0 SRM), 79.0 %
0.395 kg Wheat Malt, Bel (2.0 SRM), 12.0 %
0.140 kg Caramel/Crystal Malt – 40L (40.0 SRM), 4.3 %
0.140 kg Caramel/Crystal Malt – 75L (75.0 SRM), 4.3 %

21 g Fuggles [4.30 %] – Boil 1.0 min, 3.2 IBUs
1.0 pkg Fermentis SafAle S-04

01/01/2013 – I wanted to test my process to see if I can get a consistent efficiency with my BIAB process, even if that efficiency is very low. So I used the same volumes of water and the same method of sparging. I think I may have rinsed the grains a little better in the sparge pot this time though. My OG, which I measured after topping up to about 13.5 litres was 1.052! So I topped up further to the 15 litre mark. This beer is understandably a little darker than my Fool’s Gold Bitter because it has a greater amount of crystal malt. I pitched about 400ml of the S-04 yeast slurry into my 15 litre fermeter and it’s bubbling away like a beast. Hopefully I can get another 25 bottles out of this batch.

I was feeling so smug that I immediately set about doing another batch of beer. Bad move, as it turned out. Here’s the post about it, “Pie-O-My” Amber Ale.

10/01/2013 – Bottled to 2.2 volumes using 75g table sugar. I got 25 bottles out of the batch as expected.

18/02/2013 – I can’t believe I haven’t posted any tasting updates on this beer as I’ve had a few tasters at this point. It’s suffering from the same S-04 bite that has plagued my Tailgunner Best Bitter so far. It’s much murkier also, but it remains to be seen whether this is due to the sizeable portion of wheat malt or whether it just hasn’t dropped bright yet. As you’d expect, it’s got much more caramel and hop flavour, a bit fruitier perhaps. The Tailgunner seems to only now be getting better after 6 weeks in the bottle, so maybe the same will apply here. I’ll taste again at the end of the month.
