Brewday - November Rain II - 22October2011

[bosium]

I'm off on holiday back to SA in three weeks' time, so I'm on a bit of a mission to fill my kegs with beer so they can lager while I'm away so that I've got something to drink when I get back in December (brr!).

I brewed 5 gals of German pils about a month ago, as simple a recipe as any but always turns out great. I'm repitching the yeast from that batch into these - 10 gallons of my favourite recipe. I'm hoping to get them into the keg for lagering just before I leave, which should give me approximately 8 weeks of cold conditioning before the festivities of the new year.

Awesome matey! Really nice looking recipe.

NIce brewday, that is a very full mash tun!

[bosium]

@LB - thanks, it's an old tried-and-tested for me. Just the right balance of sweetness and toastiness / nuttiness for my palate.

@pdtnc - yeah, tell me about it! 10Kg grain + 20L water in a 30L MLT is really stretching the limits of my system. I'm desperately in need of a shiney 50L thermopot to convert to a MLT, I have the stainless false bottom already. Still, such a pleasure to be able to make 10 gals of lager at a time now!

[bosium]

this made it down to about 1.014, for an ABV of nigh on 5%. It tastes pretty good now, dropped clear and green hop taste just about gone, quite full-bodied. the beer has a brilliant head on it and laces all down the glass. Very pleased.

Will try grab a picture of it.

How well does the mash tun retain the heat?
I have one of those lying around at home but didn't think it would hold the heat that well!

[bosium]

Actually it works brilliantly well! The thing is to remember to preheat it first. Also, as you can see, I have it full to the brim which also helps a lot.

I also wrap it up in a blanket for the hour and it loses at most 1degC over the hour. I could really use a bigger MLT for the 10 gallon batches but it just about works so does me OK for now!

[jonnyt]

Thanks for that.

Jonny - not thinking of going 3V are you? if you do you'll have to delete all your other comments about BIAB being easier etc!!

[bosium]

Nothing wrong with BIAB, I've made some great beers that way...

[Goulders]

I BIAB too - just light hearted joke with Jonnyt if he is thinking of going 2/3V!

[jonnyt]

I'm thinking of batch sizes.
Greater than 30L I cannot lift the bag!

For larger batches and also potentially smaller trial brews I'm considering a 2V actually with a mash tun and a boiler come HLT

I'm also trying a No Chill cube and dry hopping.

All part of the fun.

[Goulders]

I haven't dry hopped yet, but need to give that a go sometime
