How long to boil dme?

I'm brewing an IPA and using Cooper's HME IPA. I'm also using Muntons extra light dme for the first time and don't know how long to boil this.

I plan on doing:
a hop boil of 14 minutes 1oz cascade pellets/muslin
a hop boil of 5 minutes 1oz willamette/muslin

I know not to boil the HME, but how long to boil the DME total time including the hop boils?

 

Don't need to boil it long. I would recommend just bringing it to the boil long enough to create any break material.

Many people add it at flame-out.

Let the hops dictate how long you need to boil it.

 

It looks like you need a minimum of 14 minutes of boiling based on your hop schedule.

Based on your hop schedule, I would personally probably just boil for about 20 or 25 minutes, adding hops in the last 14 minutes and 5 minutes, and hopped malt extract after the flameout.

 

Thanks Guys! That helps a lot!
