Looking for input on my extract recipe

[Aidan Curran]

Hello,

I'm new to this forum so let me know if I'm posting this in the wrong place.

 

Based on my supplies at hand I've come up with this recipe for my next extract batch (b.t.w. this will be my 5th batch and 2nd extract batch):

Batch Size: 25L
Boil Size: 10L

Fermentables:
Steeped Medium Crystal - 0.25 kg
Amber Liquid Malt Extract - 3.75 kg
Dextrose - 0.25 kg

Hops:
Nelson Sauvin (12.6%) - 5g @ 60 mins
Summit (15.9%) - 5g @ 60 mins
Nelson Sauvin - 5g @ 20 mins
Summit - 5g @ 20 mins
Nelson Sauvin - 15g @ 10 mins
Summit - 15g @ 10 mins
Nelson Sauvin - 15g @ 0 mins
Summit - 15g @ 0 mins
Nelson Sauvin - 15g dryhop
Summit - 15g dryhop

Yeast: US-05

According to the recipe calculator I'm using, this should give:
IBU: 38.6
OG: 1.052
FG: 1.012
ABV: 5.5% (incl priming)

1. How do you think this recipe would work?
2. What style would you call it?
3. Any ideas to improve it? (preferably without additional ingredients)

Thanks in advance,
Aidan

Hey Andrew, I meant doing a 60min boil but holding most of the extract until there was 15 to go, not just a 15min boil.

 

I don't know how no gravity vs a little gravity works out, there is a table somewhere in How To Brew that approximates it

I've read and listened to some interesting stuff about the effect of BG on hops utillisation and what I gather is that the theory of BG directly affecting hops utillisation is not actually valid especially for extract brewing. Experiments done with full boil vs. partial boil/full extract vs. partial boil/partial extract and the exact same amount of hops resulted in very little noticeable difference between the 3. My take on it is that a safe bet is to just boil part of the ME but no need to try and target some exact BG - just roughly shoot for a BG somewhere in the range of 1.040 - 1.050.

Sounds like a plan. I gather that you are right that hop utillisation isn't effected by gravity <i>per se</i>, but the stuff that comes with it, and there might well be less "stuff" in extract brews.
