Why do a 90 minute boil?

I’ve also been wondering what the point of a 90 minute boil is, except when driving off DMS when certain malts were used in the mash.

I noticed some time ago that Deschutes indicates on their homebrew recipe pages that they do a 90 minute boil. http://www.deschutesbrewery.com/brews/homebrew-recipes. Is there some benefit of a longer boil at the commercial level, because of the increased volume or some other factor?

I’ve planned a 75 minute boil on my last 6 batches.

I was under the impression to force hot break before bittering hops are added at 60 mins. :?:

That’s what I do.

I learned on the Fuller’s tour that they do 60 minute boils. I was surprised, as almost every recipe I’ve seen from British breweries has a 90 minute boil.

The Fuller’s tour is a blast, btw.
