    And sadly all gone now. Ah well, an empty keg is a blank slate waiting to be filled.

    It's yeast starter day today in preparation for a brew this weekend and it's the fourth and final re-use of the Omega OYL-052 DIPA yeast that I've become rather attached to since I started using it back in August. I'll be buying more of it next year but after this one it's going to be a few pilsners in a row so I'll be needing appropriate lager yeasts for those.

    Anyway, with no overbuild to consider I only needed a litre starter so I opted for the 2 litre flask. It's spinning away on the stir plate in the brew-fridge as I type.

    The beer itself will be an ordinary pale ale hopped with English hops and timed to be ready for the run up to Christmas. Recipe to follow when I've finished the customary last minute faffing with the details.

    And as usual the starter has tried to climb out of the flask. Did I mention how much I like this yeast?

    It'll be a bit crusty under the foil cap but it doesn't matter.

    Today is brew day for my English IPA that should be ready in time for the Christmas period. I'm calling it Flagstaff IPA and here's the recipe I came up with:

    Code:
    Recipe Specifications
    --------------------------

    1.0 pkg     DIPA Ale (Omega #OYL-052)                  Yeast         -      
    
    
    Mash Schedule: Single Infusion, Medium Body, Batch Sparge
    Total Grain Weight: 4.57 kg
    ----------------------------
    Name              Description                             Step Temperat Step Time    
    Mash In           Add 24.62 L of water at 69.3 C          66.0 C        60 min      
    
    Sparge: Dunk sparge with 5 L of water at 75.0 C
    
    While weighing out the grain I realised I was 2kg short on the base pale malt and I could either open a new, sealed plastic bag of Maris Otter or make up the difference with some from already opened bags of pilsner and extra pale malt. I opted to use the bags that were already open.

    [​IMG]

    I had a taste of a few grains of the extra pale. It's been open for a year and it didn't taste very fresh. Not an off taste, just not very fresh. By contrast the pilsner tasted crisp, crunchy and cracker-like. I used that and the kilo or so of old extra-pale is now bird food.

    [​IMG]

    I crushed the grain while waiting for the treated Ashbeck water to come to mash temperature. I mashed in at about 66C and left the thermopot with the lid on for an hour.

    [​IMG]

    The iodine test showed that conversion was complete and I took pre-boil measurements after doing a 10 minute sparge with 5 litres of water in a spare bucket. Pre-boil gravity was on target at 1.042 and I was about 400ml short on the predicted volume which is fine by me.

    [​IMG]

    The wort was brought to the boil while stirring and then the boil power was reduced to about 1.6kW for the duration. Just enough to maintain the gentlest of rolling boils.

    [​IMG]

    The hops for today's recipe are all English. Endeavour is an intriguing hop. Fruity, with a bit of a gooseberry bitterness, I think it will go well partnered with the earthy Fuggle flavour.

    [​IMG]

    Boil finished, chilled it down to 24C with the immersion chiller and transferred the whole lot to the sterilised fermenter. The 400ml shortfall after the mash carried over to the final volume and I got 23.6 litres into the fermenter versus the target of 24 litres.

    [​IMG]

    The wort's a lovely pale colour with an OG of either 1.044 or 1.045 depending on whether you believe the hydrometer or the refractometer. It's now in the brew-fridge while it comes down to around 20C when I'll pitch the decanted flask of OYL-052 yeast. Yeast seem to rock through the worts that I create so I've no reason to suspect I won't achieve the usual 82 to 86% attenuation, giving a final ABV of around 4.9% give or take.

    Started at 6:30am. All washed up and done by 12:30 for lunch.

    ...and the half decanted starter (I wanted 500ml to make up the volume undershoot) was pitched at 16:30. 5 hours later and I'm getting slow bubbles through the blowoff tube. Great yeast this Conan strain. Very aggressive, very reliabe.

    A less than ideal and somewhat hasty smartphone photo taken tonight as I wash down dinner with a few pints of my Outback Ale No.2.. Clarity is on-point, thanks I believe to the performance of the yeast and the Kwik-Clear finings added to the keg. The lacing of the head down the glass seems to indicate that the overall process is good but never mind that technical stuff what does it taste like? Well you need to like Nelson Sauvin that's for sure, and I do. Tempered with the tropical fruits of Galaxy and a stiff malt backbone from the Munich and Melanoidin malts I find it to be quite balanced and the mouthfeel you get from the Vermont yeast just can't be beat.

    I kegged my Flagstaff IPA today after 2 weeks in the fermenter. A very healthy 86% attenuation gave an FG of 1.006 and a final ABV of 5.0%. This was the last use of the OYL-052 yeast that I've been overbuilding for the last four brews and next it's time for a couple of lagers using Wyeast 2308 then I'll be back on the Vermont strain for some ales.
    [​IMG]
    Kwik-Clear finings were added to the keg, headspace purged with 5x15psi and I'll now leave it on gas for a couple of weeks before trying it. The sample jar tasted really, really good. I'm looking forward to tucking into this one over the Christmas break.

    Am I correct in thinking that you don't have a trub filter in your boiler? And that you just leave it to sit for an hour before draining through the tap?

    Cheers. Tom

    I drain the entire boiler into the fermenter as soon as I've brought it in and sanitised it (I keep it out of the room while preparing the wort because of the risk of contamination from grain dust). As far as trub removal before that goes, I bag my pellet hops and skim off the crud that gathers on the surface during the boil. The reason I drain the lot is to maximise the use of my fermenter which has a rather large 4 litre dead space below the outlet valve which I'd rather fill with trub than beer.

    I've always been a bit inpatient once the boil is done. As soon as the wort is cool enough I open the tap to the fermenter. All my hops (pellets), including flame out, go in a fine mesh spider that gets lifted and dunked many times during cooling. I used to have a bazooka on the tap but got fed up with it blocking so got the spider.
    I've seriously neglected my grain brewing of late so when I clear the short date kits I've got I'll dig the trusty Ace out and fire it up again.
    I'm sure I read on one of your posts that you wait about 60 mins to allow things to settle before transfer tho?

    Cheers. Tom

    Me too on the quick transfer after the boil. It's partly because I'm a bit worn out by then and am trying to get it done and also I don't like leaving wort sitting around. I like to get it in the brew fridge and down to pitching temperature as soon as I can, which could be just an hour or two for an ale or the next morning for a lager.
    Touch wood I don't think it was me that said that.

    ...and a duplicate post of my Outback Ale No.2 from the what are you drinking tonight thread just so I keep track of what I've done. I did the same grain bill for my Flagstaff IPA that's just gone into the keg today and definitely have high hopes for that one. The keg's set at around 15psi which seems a bit high given the 11C temperature in the garage at the moment but subjectively the amount of carbonation I get at that pressure seems 'about right' for an ale.

    You do get some really clear wort though. So jealous.
    The hot/cold break obviously don't cause any issues then. Break material is supposed to be very good yeast nutrient but it looks horrible so I don't like it going into my fermenter :(

    Cheers Tom

    I'm sure there are many factors that help bring about a clear beer, luck being one of them. That said I've had no trouble getting a crystal clear beer as long as I use protofloc. I don't cold crash, and although I try and leave the very bottom of the trub in the boiler most of it goes in the fv. I reckon water quality and luck works for me.

    There's so many variables, it's hard to pinpoint the cause I suppose.
    Once I get the Ace up and running again I'll have to try your mainline bitter. Superb looking pint, some other tasty looking formulations in this thread too.

    Query......... Do you keep a stock of base malt then buy the smaller weighments and hops as a "kit" from the likes of the malt miller?
    I've had a 25kg sack of Bairds pale opened for over 12 months, I hope it's still usable. Been kept dry and sealed so fingers crossed

    Cheers. Tom

    I can vouch for the mainline, brewed it twice. Lovely.

    Mash Schedule: Single Infusion, Medium Body, Batch Sparge
    Total Grain Weight: 4.59 kg
    ----------------------------
    Name              Description                             Step Temperat Step Time   
    Mash In           Add 24.63 L of water at 69.3 C          66.0 C        60 min     
    
    Sparge: Dunk sparge with 5 L of 75C water
    
    Although the recipe states Ireks pilsner malt it's actually 50/50 Ireks and Weyermann Bohemian because I can't get Ireks any more since it mysteriously disappeared from the Geterbrewed site without warning or explanation. The Weyermann Bo-Pils (not floor malted) has a great reputation so I've got no problem switching over to it.

    I got started at about half ten this morning; a bit late for me because I got back from hols at 1am and had to go out to buy the Ashbeck water this morning before I could get started. I measured out the grain while the water was heating:
    [​IMG]
    I crushed it as strike temperature was getting close:
    [​IMG]
    No problems with the mash, boil and wotnot and I managed to chill down to 22C with 60 litres of water before transferring to the fermenter.
    [​IMG]
    It's now in the brew-fridge to get it down to 12C or lower before I decant and pitch the 2.3 litre Wyeast 2308 starter that I created 2 weeks ago before I went away. It's been sitting in the fridge since then so should not have lost many cells.

    OG was 1.043 against a predicted 1.044. If this finishes around 1.006 as everything I ever brew seems to do then it'll be 4.9%

    The plan is for a few days at 10C until I notice activity starting to slow then I'll bring it up to 16C and leave it there for a total of 3 weeks before kegging.
