This is probably a really stupid question but has anyone experimented with continuous hop additions?

Something like 1g every minute from 60 mins to flame out or maybe 30g bittering at 60 and 1g every minute from 30 mins to flame out?

I'm curous what affect this would have. Thoughts?

Not a stupid question at all.
This is what the Dogfishhead 60 90 and 120 minute IPA's are about.

I haven't done 1 min additions, but have done 5 min additions from 45 mins to 0 mins. I know Jayse and big d have done this also.
It is a bitch to enter into Promash though, especially when each 5 min addition is the combination of two or more hop varieties.

My theory was you would get a smooth transition from bitter to flavour to aroma, if that makes sense ;)

hi wax
as doc says no not a silly question at all.
my reason to do so many hop additions was due to a brewer called cj on the homebrewer site.
basically why not.it was having rave reviews on homebrewer so i thought i would give it a go.
its a pain to do as you have a large amount of hops to measure out.you really need to be focused to do this without interuption.
you must also really love hops to do this as bonk says one massive hop hit.
as for any advantage probably not.you could do the same but in 5 or 10 minute additions and probably end up with the same great tasting beer.

cheers

Ahh, but how did it taste Doc? Surely it was worth the extra hassle?

I did a pilsener with additions at 60, 35, 20-17 (constantly dribbling it in) and at flameout.
The result was predictable bitterness, but it's just incredibly smooth and almost complex.
I think being more specific with the 'you have to like hops', you have to like the type of hops you're using.
If you know you love a hop, go for it.
Another thing, it's only really suitable for hops-dominated beers... IPAs, pilseners, maybe APAs, few other styles.
1-minute additions is pretty full on, if you've got the patience, do it.
I think DFH have a conveyor belt with hops, constantly adding it.
Another thing, it's a little difficult to predict the effect... while IBUs give you a good guide (if you're using a formula that works for you), you can't fully predict the 'presence'... hard to explain, bitterness is the same but there's just so much more hops!!
Try it... see if you like it!

I'm brewing an IPA in the next two weeks, after I bottle my APA and Convict Stout.
I'm considering doing 1-minute additions, all Centennial, but I think I'll just do the 60/35/20-17/0 + dry hop... that seems to work really well.
The grain bill is basically pale base with about 10% wheat and some crystal, and a touch of chocolate to round it off.
What do you think... go hourglass style, or stick to a tried and true pattern?
This is Centennial we're talking about, just one hop through the entire beer.

i would guess that with only centennial it would be very strong. however having said that, i'm sure i've seen clone recipes packed with centennial, or as the yanks call them Imperial IPA's :) i'm sure a beer brewed by stone's or 3 floyds is a centennial only brew or has it as the main hop.

but with all things homebrewed, it up to you, i'm sure you have already looked around the net, so why not brew it and see what happens :)

EDIT:

once i get back from my weekly outback trip, i hope to brew something like the hourglass :chug:
