Just reading it I feel like a robot!

It looks like you mash, drain, add sparge, drain, add sparge, drain, rather than mash, top up, drain etc - am I reading that right?
If so, does it help your efficiency?

How does the pre-boil of 33.92L @ 1.073 tie up with 20L @ 1.089? I make it about 1.124!

Are you going to use both WLP001 and US-05?
Looks good anyway!

[196osh]

I will lose 8L to hops and Trub, mostly hops as there is a lb of them.

Should end up with like 23L ish into the fermenter then will loose more to dry hops.

Dont know on the efficency thing. Beer Smith does it for me.

[196osh]

And yes. yeast cake which has been sitting in the fridge for a week plus a pack of US-05.

[trucker5774]

Recipe looks good.................sparge method and amount lost me a little.............small mash tun

[196osh]

Small-ish, I would probably have to do 3 sparges. Is more an experiment on if draining the mash tun more times will increase my efficincy at all.

I have done it like that for a couple.............can't say I noticed any huge difference. I have a very relaxed attitude to my brewing and try all sorts of things. I admire those with the supreme knowledge and technical know how, taking note of what they say. The reality is something watered down. I am looking forward to your results on this one. I reckon it will stand a bit of maturing, unlike my Truckers Delight!

[WishboneBrewery]

is that like 155g of Dry hops!!!
Should be fun trying to sink those!!!

[mysterio]

Good luck with it matey. I'm going off columbus a little. Something a little clovey about it which isn't too my tastes. Simcoe is amazing though.

[196osh]

Well that sheet went badly. Ended up with 18.5L @ 1083. Bloody lost an insane amount to those damn hops.

Better turn out good.

[196osh]

Now some pictures of the dramatically poorly efficient brew day. Worst efficiency ever.


All plastic HLT and Mash Tun.



Mashed in Decided to drop the temp to 65C.



Good hoppy stuff.


Running off into the boiler.

[tanglefoot]

That is some serious hopping , keep up the good work !

[mysterio]

Looks awesome!

[pantsmachine]

What % BHE did you get? I still lurk around 65 to 70%. Not bothered but hope it makes you feel a bit better about your own. Bet i can smell the first bottle of this you crack up here in Aberdeen!

[196osh]

Mines is normally 70-75%.

I got 60% today. That is pretty shit. Still means there is 460g of hops going into 18.5L of beer which is quite a whack. Will send you up a bottle if its any good.
