WLP Slurry as the yeast.

360g of late hops should be good.

This should get made within two weeks fingers crossed

I'll be very interested how your Mash goes on the 10%, do you Fly or Batch sparge, I think I need a couple of things to get the job sorted... a refractometer and to start Fly Sparging!

Technically its just a Mad-ass American Pale really

[196osh]

Batch sparge.

I have made two 9.5%+ beers abv so I think my technique will hold up fine. I am going to loose an ungodly amount of wort to those hops though so that will probably hit my effiecency.

[WishboneBrewery]

Maybe I am doing something wrong in my Technique... Hmm!

[196osh]

I'm sure your technique is a ok.

I think mixing the mash up after you add the mash out and sparge water is important with big beers when batch sparging.

What sorts of effiecnies are you getting?

[WishboneBrewery]

I did give it one heck of a good mix after adding the sparge water.
Normally on a regular brew I get 78-82% with 2 Batch sparges.
The Naked Imperial Stout after the 2 batch sparges was more like 40%, though after a 3rd sparge which gave me 10L of 1020 wort I ended up going 3 points over my predicted OG 1090 to 1093 in the FV.

I'd have preferred all the sugars to have come out without the extra volume, the longer boil wasn't a problem to get back to a sensible amount in the copper just a bit time consuming.

Oh, just out of interest, how much sugar have you used in your larger beers?? I suppose it makes sense to mash a normal amount of malt then bump it up with some sugar in the copper.

[196osh]

Depends on what type. If its a Belgian then the candi sugar was something like 15% normally 5-8% I think. The reason for the sugars is to make sure it doesn't end up too sweet. I think if you were doing a RIS or a Barley Wine(in particular) you could get away with no sugar being added because they are so full bodied.

Weirdly enough I seem to get lower effiecenys with dark beers. Might be something to do with the mash pH being dropped by all the dark grains. I dont really check the pH just use grahams water treatment calculator.

[WishboneBrewery]

yeah could be, everytime I check my pH its too close to bother about (whatever I do with the water treatments) I didn't bother checking my pH this time round.

[196osh]

I might try that the next time I make a big dark beer.

Bought some marbles today to weigh down the dry hops for this guy.

Going to buy a splatter guard to wrap round my strainer so I dont end up with that load of hops blocking up my strainer. Works out theres about 9g of late/dry hops per pint. Which is a new record for me, might even drop the volume to end up with 10g per pint.

[pantsmachine]

That's some serious heavy duty hops you are using there. I'll be very interested to see your brewday and hear the outcome.

[196osh]

Indeed. Will see how my strainer copes with that level of hoppage. .

Will be the second brew day with my wee pump. Going to build a stand later on tonight.

[pantsmachine]

Nice one, any photo's?

[196osh]

Nice one, any photo's?

Of the pump?

[pantsmachine]

pump and stand?

[196osh]

Sure two mins. I may have over played the stand aspect...

More like a bit of wood the pump is screwed to so it can sit on a stool. .

I'll hook it up and take a picture.
