NZ Sour Wheat – This is the start of my brewday on Sunday, but its still Wednesday!
I have just mashed 2.45kg of Pale malt in my old mini-mash Tun, 66°c for 60mins, then added about 2-3L of cold water to bring the temp down to 49°c with another 1kg of pale malt added to the mash to add some Lactobacillus to the Mash. I have put my little mash tun into my FV fridge set at 46°c and i hope to keep the temperature above 35°c as it says here http://beerandwinejournal.com/fossil-cove-sour-mash-experiment/ I did as it states and I covered the mash with cling-film and topped it off with a blanket of co2.

The Sour Mash:

Lager Malt – 40%
Wheat Malt – 25%
Wheat Malt, Dark (Weyermann) – 25%
Carapils (Weyermann) – 5%
Melanoidin (Weyermann) – 5%

Hops:
NZ Hallertau Aroma – 8.2 %  @ 60 mins – 20g
NZ Hallertau Aroma – 8.2 %  @10 mins – 30g
NZ Hallertau Aroma – 8.2 %  @0 mins – 30g

Final Volume: 23 Litres
Original Gravity: 1.047
Final Gravity: 1.011
Alcohol Content: 4.5% ABV
Mash Efficiency: 75 %
Bitterness: 22 EBU
Colour: 15 EBC
Mash: 75mins @ 69°c
Boil: at least 75mins

Copper Finings: Protafloc @ 10mins left to boil

I’m expecting a fair few spec-changes, I’m thinking of my combined Run-off / sparge to be no more than 30L, I may get more, I may boil down, I will no doubt have a gravity change which will also effect the bitterness…. ;-)

**Sunday**
To start off with I prepared my malts while the HLT was heating:
Image
Then Checked the Sour Mash, it was 33°c in the center and smelled like the waste malt skip at work, I’m pretty pleased it managed to stay at 33c as @lugsy51 tells me that should be alright:
Image
The top of the mash, even though it was covered in Cling-film had changed to a darker shade than the rest of the mash underneath:
Image
I added about 3.8L boiling water to the Sour mash and gave it a good stir before running off about 7L into the copper, these are the weirdest first runnings I’ve ever had, the photo below shows them as clear as they were going to get:
Image
The copper was pretty full after the main mash was sparged with about 32L in total, I liquored back 3L as the boil progressed checking with my Refractometer:
Image
I did a 10min & Flamout (90°c Steep) additions, I’m hoping the Pacific Jade will give some Orange notes which i think will compliment the Wheat beer yeast:
Image
I liquored back 3L to 1048, 2 points above my original predicted OG:
Image

I tasted the Sour wort after it had 15mins of boiling, it was very sour (like so sour I went to spit in the sink!), I boiled it down to 5L with the hope of driving off some of the smell…! Things calmed down after today’s main mash was run to the copper with the wort ending up with just a subtle tang behind the malt sweetness at the end of boil, I’m told the sour will increase as the wort ferments and the sugars are used up.
Yeast was rehydrated and pitched into 30L at 20°c.

Things went very smoothly even with extended boil times running off the small sour mash worked well while the main mash was having its mash rest then the rest of the brewday was as per usual with just a slight lingering smell of the sour mash in the house, I was expecting worse! 🙂
Fingers crossed on this one as its all new to me!

*24th Sep ’13 – Gravity at 1019 and tastes pretty ok, a cider-like bite/tang.

*27th Sep ’13 – Gravity at 1018 and looks to have finished, have given it a rouse and will check again tomorrow, at this rate the beer will be really balanced against the lactic sourness.

*28th Sep ’13 – FG seems steady and I’ve just dry hopped this with 22g Motueka I had in the freezer.

*Bottled 5th Sep ’13 – Primed about 24L with 165g White Sugar, its got a permanent haze and tastes like cheap orange juice, though the balance of sweet to sour is quite good, hopefully it will carbonate up well and give it a crispness. With its starting and finishing gravities this beer is actually 3.9% ABV.

*16th Oct ’13 – Taster time… Yeasty Clove on the nose, quite light sparkling body on the pallet with a tang like fresh squeezed oranges. I’m hungry and this is making my belly rumble, bitterness is subtle and quite chalky but its hard to detect as the sourness and prickly carbonation cross the tongue first, with a few more mouthfuls the body feels to have a slick quality like a good Belgian Wit.

Pacific Rim – Light coloured beer stocks are low so I hope this to be a hoppy easy drinking beer, bittering from Simcoe and very kiwi Flame-out steep, I had a hop-freezer rummage and found a half pack of Riwaka… nice 🙂
The name ‘Pacific Rim’ is sort of an evolution from my Ring Of Fire which was all New Zealand grown hops, I didn’t realise until afterwards that there is a movie of the same name which looks pretty cool.

No messing today, added some spacing pieces inside my Mesh Hop-Stopper so that it can’t lay too flat, compact & block, had lovely clear and timely run-off to FV.
Slight Schoolboy error was miss-reading the calculator and liquoring back an extra litre doh! Not the end of the world!
Tucked up in the fermentation fridge at 20°c, the yeast should make fairly short work of this.

*2nd Feb ’13 – This is tasting pleasantly light and drinkable, down at 1008 pretty sure its finished, happy so far 🙂

*Bottled 5th Feb ’13 with 100g White Sugar.

*12th Feb ’13 – this is very drinkable, subtle orange and berry with some light woody notes, a crisp bitterness and finish. I could easy drink a few of these 🙂

Klaatu Verata Nictu – The New Years Day BrewAthon 2013. It was a year ago that a few of us brewed an Imperial Stout on New Years Day, this year its a more free range of beer styles but people are pushing the boundaries a little with some funky yeast etc
The name for this beer comes from http://en.wikipedia.org/wiki/Army_of_Darkness quite the classic.
I’m making a big beer, 10% ABV with Amarillo & Delta Hops, I’d like to brew a beer that will evolve and change over a couple of years (hopefully it will last that long!) something with at least a hint of what my Imperial Amarillo Wheat had after 18 months.
Once I’ve fermented mine with US-05 I’ll be bottling half-ish and then using Brettanomyces Bruxellensis in a secondary fermenter.

These NZ Sticklebract smell great, big pungent citrus character, bit of a shame they are just the bittering:
Image
New Year Resolution is to brew my way thru some of this lot!:
Image
After 2 hour mash I’m recirculating the wort for clarity, tastes good:
Image
About OG 1090 give or take, a temperature corrected Hydrometer test showed 1083 a more reasonable figure, the mash was actually pretty text-book and the recirculation must have helped:
Image
Boiling down the wort in the kitchen too so as to speed things along, I did this with some of the first sparge and again with the second sparged wort:

Amarillo and Delta 80°c steep hops:

Almost 1110 off the scale, this is going to be a fun liquorback:
Image
Finally after a mega dribble transfer I have pitched 3 packs of yeast!:
Image

Everything was going sooo well until I got about 10 Litres transferred into the FV when it ground to a halt (Dribble) and I started to try and find a way to make it speed up so cleaned a Solar Pump and pipework and tried pumping it… sadly I just got the same dribble but through a pump, left it to it and came back about 9pm to find about 20 Litres in the FV. I was over my OG so I liquored back to just over my target and gained an extra couple of litres, there must have still been 4-5 Litres left in the soggy hops in the copper, If it had drained properly I’d got that extra out and would have split the batch into another FV and left the Brett to do a full primary ferment.

My Method for brewing this 10% beer:
This is how I have done my Barley Wine and Abyss Imperial Stout, Over-sparge by 10 Litres or so and boil it down in a few pans before adding all back to the copper and boiling down until I reach the theoretical pre-boil Volume, then add the 60min bittering hops and so on until the end of a boil. The Mash and Sparges were; Mash with hot liquor at 73°c for 120minutes (65c Mash); recirculate entire mash via solar pump for approx 20mins; drain Mash completely avoiding malt particles at the end; Sparge with 13.4L Hot Liquor at 78°c recirculate and Run-off; Boil down in pans; Second 10L Sparge Recirculated and Run off with a further boiling down.
As I was saying above I was actually finishing the boil with a good few litres more in the copper and was hoping for extra in the FV… oh well!

I may have to look at improving my Mesh Hop-Stopper for brewing these bigger beers that include some Pellet Hops.

This years brewers were:
Here is Barney’s on JBK – Monks Slipper

Here is Lugsy’s on JBK – Pseudo-Lambic (Lugsy started early as he’d learned from last year!)
Here is Leedsbrew’s Prep Blog and later Update
Here is Quadrangularus’Raspberry Sour Brown Ale

More as and when the brewers post up their Brewdays

*12th Jan ’13 – Gravity at 1019 so 10.9% ABV, dry hopped with pellets:
Nelson Sauvin – 29g
Motueka – 29g
Cascade – 29g
I decided not to go down the Amarillo whole hop route as they would soak up too much beer and I’ll be splitting some of the beer off into a Demijohn or small FV bucket to Brett so don’t want to loose too much volume.

*Bottled 20th Jan ’13 – with 65g White Sugar, dropped the lot into a Bottling bucket with primings then bottled half-ish in 330ml bottles then put the rest in an Oxfam bucket and pitched the Brett.
Syphoned thru a Teaball to guard against getting pellet debris in the bottles, the chill down to 8°c in the fridge had made it pretty clear anyway:
Syphon Teaball
Brettanomyces Bruxellensis added to about 8L in Oxfam bucket:
Brettsnomyces Brux added to about 8L in Oxfam bucket
Got about 32 bottles, tasting pretty good with a fair amount of residual sweetness which should fade in bottle as it conditions and matures:
Bottled ag#92

*2nd Feb ’13 – Brett’d beer has dropped 2 points to 1017 from 1019, very slight speckled surface, think it needs more brett! Tastes just slightly different to what I’d expect from un-brett’d.

*2nd Feb ’13 – Had a taster bottle with Dave last night, has loads of residual sweetness which I hope will diminish as it matures, could have done with maturing in bulk then Dry hopping and bottling some weeks/months later.

*9th Feb ’13 – Just added a fresh tube of Whitelabs WLP650 as I was expecting more to be happening and wondering if the OG / Alcohol content is screwing the Brett Brux over.

*25th Feb ’13 – Gravity @ 1017 which hasn’t budged in the last 23 days! Tastes just on the edge of bretty-sour but very subtle. I’m fairly sure the High Alcohol has killed the Brett.

*31st Mar ’13 – Gravity @ 1015 so its creeping slowly and is now showing a more Bretty sour, it could be some time before this is finished!

*11th Aug ’13 – The Brett’d batch gravity is 1014, I doubt it is going to go any further, tastes different maybe not what I’d hoped for…

Ring of Fire – This is a brew using two New Zealand hops I’ve never tried, ‘Pacifica’ and ‘Pacific Jade’ the latter smells like a cross between Citra & Nelson Sauvin to me…
The name is taken from the the hops / Pacific Ocean / volcanic “Ring of Fire”, part of which passes through New Zealand giving them Geothermal activity and Earthquakes.
A fairly sensible malt bill with German Munich Malt for some maltiness and Cara-Pils & Cara-Belge for some body & Sweetness, I’m going fairly restrained on the early bittering and quite light on the 5 minute hops as I want to leave the Dry Hopping to do the talking which will be the remainder of the two 100g packs of hops, should be around 50g of each.

Fermentables:
Lager Malt – 75%
Munich Malt I (Weyermann) – 10%
Carapils (Weyermann) – 5%
Flaked Oats – 5%
Cara Belge (Weyermann) – 5%

NZ Pacifica – 6.1 % @ 30 mins – 10g
Pacific Jade – 15.1 % @ 30 mins – 10g
Pacific Jade – 15.1 % @ 5 mins – 30g (with 20min Steep)
NZ Pacifica – 6.1 % @ 5 mins – 30g (with 20min Steep)

Dry Hops: (These will be added near the end of fermentation before cooling)
Pacific Jade – 50g
NZ Pacifica – 50g

Pretty straight forward brewday, bleached a couple of crates of bottles thoroughly in amongst brewing to prepare to bottle AG#82 on Tuesday-ish 🙂

Liquoring back:
Its pretty easy to use a Smart Phone based app to help you calculate your liquoring back volume, but probably just as easy to use a calculator, it goes a like this.

Wort OG x Volume = (Litre Degrees)
Litre Degrees / Target OG = Volume to make up to with Liquor-Back
(We drop the leading 10 from the 1053 giving us 53)

Its important to read your Hydrometer/Saccharometer correctly and adjusting for sample temperature and know an accurate volume for the wort that you’ve collected.

*Bottled 15th Jul ’12 – with 90g sugar to 20.5 Litres of beer, tastes pretty green / grassy / zingy / catty, will probably take 2 or 3 weeks to settle down in the bottle.

*18th Jul ’12 – Cheeky taster, Orange zest and smooth, slight musky edge… bet would work well as an IPA or just a lovely refreshing summer pint.
