No Chill only 40 min boil required?

[gordo_t]

Get some best pilsner malt and give it a crack and report back h34r:

Just finished 'Chappo's standard aussie lager' with a 40 minute boil, will let u know how it goes.

Common brewing wisdom suggests you should boil for 15-30 minutes before the first hop addition to get the best utilisation (break material can affect isomerisation/utilisation)

What sort of effect does first wort hopping have regarding this?
