The Results are in! (well sort of)
I conducted my "no sparge - full boil volume" Vienna Lager experiment this afternoon, and I can honestly say that this was my easiest brew yet.
I'm not sure if it's because I am getting more familiar with my procedures or the ""no sparge - full boil volume" is a winner. I think a bit of both, certainly the clearest wort I have produced.
I apologise for the length of this post in advance. (still not as big as some of the other posts I have read, not naming any names .....PP oops.
I do 15 litre batches (kettle size limitations, BigW 19 litre pot!), then usually add 3 litres of cooled boiled water into the fermenter.
I am trying to get my measurments and water usage with my equipment correct, hence the full volume experiment. I thought by dumping all of the water needed into my mash tun, including 2 litres for Mash Tun deadspace, and 1 L/Kg grain absorption, I would be able fine tune my volumes needed.

Mash in Add 22.00 L of water at 71.1 C 67.0 C 60 min
I set my efficiency at 60% as suggested by somebody earlier, and conducted a 90 min mash and stirred every half hour. I took a hydrometer reading on hour mark which was 1.052 (temp adjusted on beersmith), not far off my target of 1.052, (although as I add water into the fermenter anyways, no probs). Had 1.052 at the end of the mash too and actually ended up with a 62.2% efficiency into the boiler.
1 hour boil - everything as planned, lost just over 3 litres to boil ended up with just under 12 litres left, will probably lose another litre to trub even tho I use one of Ross' excellent hop socks. B)
If there is no real difference in quality/efficency by using this method, then I think it will definately help newbie AGers like myself come to grips with what at first seems like alot of complex information and setup costs, taking the plunge and producing fine beer from grain. If it is just a matter of spending another $1 or $2 on grain for each batch, to produce a maltier beer, and simplify your procedure in the process, then I think I will be exploring this method more in the future. I also intend to do this same recipe with the "no sparge Mash out" method, (partigyle - thhnkyou TL), I described in an earlier post next time to guage the difference if any. Will post my results once conducted.
here are some pics....

The Boil, (love that hopsock, held up by Luigi the spaghetti twurler!)
BTW.. This brew is chilling out on the concrete floor of my back shed, no chiller style(should get down to 7-8C tonight), til the morning when I will pitch the 2206 on her.
