BIAB#1 – Tailgunner Best Bitter

20121222-215357.jpg

I was waiting until the Christmas holidays to do my first all-grain recipe. For the first time ever, not a gram of extract will go into my beer. Not having a mash tun, or even the expertise for conducting a mash using a 3-vessel system, I’ll be using a BIAB method using my two pots. The pots are 20 litres and 10 litres and I’m slightly restricted on boil volume because I’m boiling on the gas hob. So I’ll be doing a slightly smaller batch of 15 litres because I don’t wait to boil at too high a concentration and end up with excessive kettle caramelisation. My previous partial mash efforts have been running at a pretty rubbish 65% efficiency, so for my first BIAB I’m going to use an even lower figure of 60%. If I get a higher efficiency than that, then great. The 30 IBU I’m planning will hopefully stand up against an extra couple of points on my original gravity.

Notes

Boil and mash conducted on the same day. I used a much higher boil volume than usual, must have been at least 15 litres, but the hob handled it just fine. I got about 11 litres into the fermenter and had to top up with some water. Fearing a very low efficiency I added water up to 13/14 litres ans took and OG reading of 1.048! Pretty good, so I topped up to the 15 litres mark. The next step will be to actually calibrate these fermenters I’m using.

30/12/2012 – Bottled using 90g table sugar. Bowled over by the sample I took from the fermenter. It’s really bready or grainy, I can’t figure out which word describes it best. Nor can I figure out what has contributed to this flavour, the torrified wheat or the biscuit malt. At this point, I’m going to guess that it’s the torrified wheat given that it’s a very traditional grain in English styles, and my beer tastes very typical and traditional. Should have a nice level of carbonation with the 90g of of sugar. It’s quite bitter, more than the 30 IBU that I was expecting. Got a FG of 1.008. Will give this 3 weeks conditioning before trying a sample. I saved 500ml of slurry that will be rolled over into another all-grain English bitter. This time, it’s going to be based on a clone of Goose Island Honkers Ale – itself based on an English bitter. This will be more caramelly with plenty of fermentables coming from wheat malt and also a little roasted barley for extra character. I’ll be using all Fuggles for this brew, though I might not have enough. In that case I’ll use some Northern Brewer for bittering.

13/01/2013 – I should have been a bit more patient with this. The first taste is a little disappointing. Bags of potential there – a great grainy flavour and some nice residual sweetness from the caramel malt, but it just tastes like an immature beer. A little bit yeasty too, but in fairness, it was only in the fridge for a few hours before I opened it. Another 2 or 3 weeks in the bottle and I reckon this will taste excellent.

24/01/2013 – Over a week later and still no improvement. It still has that S-04 taste. I think this yeast and myself are finished. Which is a pity, as I’ve 75 bottles of beer to drink that were fermented by this yeast!!

31/01/2013 – Opened another bottle and there’s a definite improvement. The beer is now a lot brighter, which i assume is not just because of a warmer temperature and less chill haze. There’s definitely still a yeast bite to the beer though and I reckon it’s going to need another few weeks conditioning. On the plus side, there’s some fantastic grainy, malty flavours coming through. The bitterness is quite full-on for a 30 IBU beer, but it is quite light in body. All in all, there’s now a great English malt and hop character showing through and fingers crossed it will be drinking very well in a month’s time. I’ve decided that I’ll definitely be trying liquid yeasts when I do my next set of English ales. I’ll probably go for the WLP002 as it’s supposed to have low attenuation with high flocculation – a low maintenance yeast, which is pretty much up my street.

12/02/2013 – This is definitely drinking better now. It’s lost most of that yeast bite and unsurprisingly, it has dropped incredibly bright. This thing is sparkling! It’s strange though, on some sips you get lots of that grainy-bready flavour; other sips not so much. I’ll be entering this in the competition anyway and I’m looking forward to getting feedback on it. Another months conditioning should do no harm. I do think the bitter is overcarbonated though; I’ll definitely reduce the amount of priming sugar for future bitters.

18/02/1013 – Absolutely sparkling and the flavour has really improved. 6 weeks seems to be the sweet spot in a moderate-gravity bitter fermented with S-04. I do think it’s overcarbonated though which gives it a slight astringency. I might try dialing back on the hops next time too, say 28 IBU. Still not much head on the beer either.

PM#7 – Big Dawg Imperial Amber Ale

IMG_0444

This is going to be my first attempt at a West-Coast American IPA. This generally means a very heavily hopped ale with vast quantities of late hops to preserve the intense citrus flavour and aroma. This will be my first time using the Summit hop, a variety which tends to divide brewers, so I’m hedging my bets and adding equal quantities of Cascade, a perennial favourite of craft/home brewers.

I’ll be taking some inspiration from The Mad Fermentationist and attempting to make this an “amber” IPA. For this I’ll be doing colour adjustments using chocolate malt. I’ve got some wheat malt and biscuit malt in there for head retention and a bready flavour respectively. I’ll also be adding a little corn sugar to increase the attenuation and ensure that this high-gravity beer doesn’t taste too syrupy.

This is the most heavily hopped beer I’ve done to date, with close to 200g going into a 15 litre batch. Brewdog, eat your heart out! 🙂

Mash Day 03/12/2012 – Heated 8 litres of water to 72°C for mash in small brewpot. Doughed in and mash temperature settled at 67°C. Excellent. Checked after 30 minutes and mash hadn’t lost a degree so I just left it at 67°C and didn’t apply any heat to the pot as I usually would. Mash was pretty loose so I might increase my mash/liquor ratio next time in order to get more grain into my mini-mash beers. I had 5 litres of sparge water heating in the large brewpot (the kettle) but I overheated it. I added a big glass of cold water and added it but that only cooled the water down to 71°C. I figured the higher temperature might help my efficiency as it would function as a “mash-out”, dissolving some extra sugars during my dunk sparge. I didn’t squeeze the grain bag at all but I’ve got nearly 13 litres of wort now sitting on the stove and no idea if I’ll be to bring that volume to a boil. I suppose I can always boil a portion in the smaller pot if necessary.

The wort is a bit darker than I intended, but it might still come out as “amber” in the finished beer. Smells very, very nice.

I’m in a serious quandry over the Summit hops. After doing some more research on ‘tinternet, I’m seeing a lot of negative comments about Summit giving off powerful onion/garlic flavours. And the information is completely inconsistent. Some people are advising only to use as a bittering addition. Others are recommending only to use it as a late addition or dry-hop. I’m going to open the bag tonight and if I think they smell nice, I’m going to use. If they smell rank I’ll replace with Columbus. Either way, I’ll hopefully end up with the dank, powerful, hoppy IPA I’m looking for. (My next IPA is going to be lighter, slightly less pungent on the hops (Amarillo & Centennial) and slightly less alcohol.)

Brew Day 04/12/2012 – I set some heat under the brew kettle and cracked open my first ever bag of Summit hops. Got a blast of tangerines and some pungent piney aromas. That’ll do me. So I followed my original hop schedule and hopped with Summit and Cascade. It took a while to come up to a boil but the cooker just about managed it. Serious amount of hop material which I strained out using a sieve. I was too tired to calibrate my large fermenter as planned so I just topped up with water to just over 13 litres and got an SG reading of 1.078. SO I added some more water to just under the 15 litre line. I didn’t want to overshoot it as there was a lot of foam on top of the wort. I pitched about 400ml of yeast slurry from the “Hoppy Feet Pale Ale” which is just over 2 weeks old. It’s currently foaming away. I hope to get 24 bottles out of this batch given that I’ll be doing a very big dry-hop. The sample from the trial jar was incredibly sweet and very hoppy as expected. I’ll probably leave it go for 2 weeks before dry-hopping for a week.

11/12/2012 – Dry-hopped with 28g Cascade in a muslin bag weighed down with 2 sanitised shot glasses. I also topped up with a little extra cold water as i don’t want to overshoot my FG.

16/12/2012 – Bottled using 90g table sugar, my first time to use plain old sucrose. Based on 14 litres at 2.5 vol. In actual fact I got less than 14 litres out of the batch, so I hope it’s not over-carbonated. I was happy to get two whole crates (24 bottles) out of it, though I did have to pull off some very yeasty beer out of the first fermenter using a turkey baster in order to make up the last bottle. For the first time ever, I didn’t have a taste – hope it’s okay. Smells very powerfully hoppy so I might have to leave this alone for a few months to let it calm down!

12/01/2013 – First taste and the surprising thing is that it’s extremely mature and drinkable after less than 4 weeks in the bottle. The hop flavour and aroma is absolutely awesome – lots of orange and grapefruit underpinned by a smooth toffee backbone. The biscuit and wheat malts are in there too, giving a nice grainy flavour. The only downside in an otherwise amazing beer is that the colour is far too dark. Not that I’m bothered about where it fits into the style guidelines, but the fact that it’s quite cloudy from the intentionally excessive hopping means that the beer looks extremely murky. No bother, I’ll drink with my eyes closed. And omit the chocolate malt next time..

13/01/2013 – Tonight I had a very nice example of the India Pale Ale style from the Norwegian craft brewery, Nogne. Very delicious obviously, but it’s interesting to note the differences between a commercial IPA and my homebrewed version. Even though both beers were exactly 7.5% ABV the commercial beer was so much drier. Extremely dry in fact. I can’t imagine Nogne are using sugar to dry the beer out so I can only conclude they achieve this by using a low mash temperature and judicious use of crystal malts. Don’t get me wrong, I’m really pleased with my own beer, it’s just not really an IPA. I think it would be better described as an “Imperial Amber” ale due to the colour and the much higher sweetness and body.

08/02/2013 – Very high hopes for this beer in the forthcoming National Homebrew Championship. I’ve entered it as an “Imperial Amber Ale” in the “Specialty” category – a safer bet as it doesn’t fit into any other category. It’s like a super-charged version of 5am Saint, though it doesn’t have the same dank hop flavour.

06/03/2013 – What a fantastic way to finish this post. “Big Dawg” Imperial Amber Ale won a bronze medal in the inaugral National Homebrew Championship. The beer scored a whopping 40 points (the best of show also scoring 40!) to win 3rd place in the “Specialty” category. The category winners were decided by the following judges:

  • Grainne Walsh (Co-owner and brewer with Metalman Brewing Company)
  • Patrick Gallagher (Brewer at Donegal Brewing Company)
  • Ciaran Kelly (Qualified professional brewer with Carlow Brewing Company, producers of O’Hara’s)
  • John Devlin (Premier International, Beer Importers)

Now, what to do with the remaining 3 bottles… 🙂
