Is there Something magical that happens at the hour mark? Do the beer gods relize that a pot of colorful liquid has been boiling for one hour freeze time And replace the colorful water with amazing beer? (ok prob not the second one) but really is it just an algirytham that some one figrued out one day in brewholla?

Actually some beers it's better to boil for 90 minutes. Like with a large amount of pilsner in the grain bill you do that to drive off the dms precursors.

It takes a vigourous 60 minute boil to fully isomerize the alpha acids in your bittering hops.

If you play around with hop additions in any brewing software you can see the difference in the ibu's of beers, depending on when you add you bittering hop additions.

so it's all about the hops? no other real reason (other than DMS in a pils)?

Sometimes rather than "time" the boil for 1 hour, I will just boil till I reach my required final volume. Later addition hops are moved to be at the appropriate time before flame out.

What Revvy said. In general, one hour is enough time to get the bitterness out of your first hops addition. More won't do much better and less won't do as well. Some beers will do better with more or less time, but 60 is a good general rule of thumb.

Also, like wilserbrewer said, to achieve a certain final volume.

As a hophead, I like that question!


Yes, I've found out through my first three brews as 'head' of our crew, doing the calculations and supervision, boil is a good factor in determining final volume of wort.

I've been experimenting with adding my bittering hops at for 40 mins instead of 60 in some hoppy pale ales (I still do a 60 min boil, just don't add bittering hops until 40 mins in). The result is a smoother and not quite so sharp of a bitterness. Quite pleasing really.

+2, my boil-off varies so much depending on the season I have found myself playing it by ear lately.
