Default AG BIAB #2 Tweaked Greg Hughes Summer Ale

Nearing the end of this brew day now. Went for a tweaked version of the Greg Hughes Summer Ale, keeping the malt bill (sort of) but switching out the hops.

Malt bill:-

3440g Crisp Maris Otter EBC 5.7
300g Crystal malt EBC 130

Strike water heated to 66 degrees C, mashed at 65 degrees C for 90 minutes.

Hops:-

60 mins Citra 12.6% AA 10.6g
30 mins Cascade 7.0% AA 13.8g
30 mins Citra 12.6% AA 5.1g
1 min Cascade 7.0% AA 13.8g

1/2 protofloc at 15 mins
Wort chiller in at 10 mins

Mash water I used 18 litres of RO, then topped up with 6 litres of tap water treated with a 1/2 campden tablet. Tested the mash pH, got a not too shabby 5.4. I also got a much better mash, with an SG pre boil of 1.041, so I'm happy with that.

60 minute boil. I had to use just the 1600 watt element for this, as with both on the wort was literally leaping clean out of the boiler... Not talking boil over here, but literally it was sploshing. No foam problems as I gave Brupaks anti foam a go, 4mls in 100mls of RO water, about 5 sprays killed the foam dead.

Just cooling the wort now (got the yeast rehydrating too, 1 packet of CML Real Ale yeast, re-hydrated at 28 degrees C). Wife just informed me the wort has hit 22 degrees, so back soon, hopefully with more good news.

Right, all sorted finally.

I got 19.1 litres into the fermenter from the kettle, but a fair bit of trub in that, and the bazooka kept blocking something rotten. I used a hop bag for the hop pellets, but I got a lot of hot and cold break form, and it glooped the bazooka up big time. Wort was 1.046 though, and I was aiming for 1.038. Beersmith 2 told me that adding 3.9 litres, bringing me to 23 litres in the FV, would give me an OG of 1.038, so did this. It didn't, it gave me an OG of 1.040.... I decided that'd do just fine. Beersmith 2 reckons I got a brewhouse efficiency of 75.74%, and believe me I can live with that! Also informed me that I got a mash efficiency of 84.3%. As you can see, much better numbers than me previous 2 attempts at AG. New equipment and using mostly RO topped up with some tap water seems to have done the job nicely for me, that and the good advice I received here and elsewhere naturally.

Oh and before anybody asks, it's CML Real Ale yeast, so yeah darn right I fitted a blow off tube!!!!

Was a much more relaxed brew day, I took my time and eased into it. No stressing (apart from when the dog decided she needed to go out 30 seconds before I needed to put the Protofloc in, and naturally my wife was mega busy and couldn't... lol), much more what I was hoping for when I took the plunge into AG brewing. Started (properly) at 3pm, finished (including nearly all of the clean up) at 22:30. So 7 1/2 hours, but with practice I'll get that down, maybe.

Good job I fitted the blow off tube... Krausen is behaving better than usual (suspecting the antifoam has a hand in this), but it's bubbling so hard and fast an airlock would have emptied in about 20 seconds....

You'll have to let me know if it's good bud.

As usual, the CML yeast has gone nuts!

Most vigorous bubbler I've had yet I reckon. Lol

Did you add any calcium?
You need a minimum of 50mg/l some believe 100mg/l for beer.

That yeast is crazy, mine went like that - I did fit an airlock with plenty of headspace, there were no gaps between the bubbles just a constant stream of CO2

I wonder why it's so vigorous? Is it just healthy yeast that hadn't hung around like some of the packets kept in warm shops?

Yeah, in the 6 litres of tap water I used, our tap water is rock hard with really high calcium levels, hence I mixed it with RO. Even then my mash pH was still 5.4 rather than a perfect 5.2.

No idea bud, but I found the US Pale Ale yeast they do just as lively. Oddly their Saison yeast is anything but...

Good to hear! Hopefully changing the hops doesn't ruin it.
