Hop Boil length question

[fbsf]

I understand a boil of at least 60min is required with all grain, to drive off any DMS and to secure a reasonable hot break.

However, is it necessary to include hops at 60mins? I understand that an hours boil will isomerise the alpha acids better, but could you, say, add double the hops at 30 mins and get the same effect whilst retaining more flavours/aromas?

Just wondering really...

nope, not at all! google 30 minute ipa and you'll get an idea. it's used for APA's a lot to add more hop flavour with less bitterness.

Cheers for that Rob - I didn't know if it would affect the longevity of the brew - the preservative aspects of the hops.
