Vermont DIPA

Hi,

Any reason for the dme?

I would think about dropping the 60 mins hops to 30 mins. You will get bitterness from the whirlpool

I was trying to up the gravity without adding loads more to the mash tun (it'll probably be at it's limits with 8kg of grain)

I was trying to push abv to try and get in the DIPA range.

How about adding some sugar. My understanding is things can get too heavy and cloying if you use too much grain in these big beers so simple sugars are used (in particular with belgian beers) to get you up to your targer ABV but also thin out the body

I think the recipe looks good I'm currently brewing something very similar (see here).
Much like mine, you're sort of between styles there. As others have said, it'll be a lot more bitter than the calculated IBUs suggest, but on the other hand it'll probably be a bit too rich and full bodied for a DIPA. If that's what you're going for then great. I'm only having concerns because I want to enter a competition and I don't know what category to enter.

I wanted to enter the feb forum competition but I think the ibu is too low...

I really enjoy the juciey mouth feel youd get on this but I think youre right about being caught between styles.

Try something different and go traditional (if there is such a thing) DIPA?

Don't underestimate the bitterness you'll get from that big whirlpool addition. Brewing software will say it adds 0 ibu but that's definitely not the case. I'd hazard a guess that you'd be closer to 60 IBUs tastewise.
I say go for it as it, it'll be great. And the forum judges won't be too hard on you for stylistic inaccuracy.
