NEIPA oxidation

[dan125]

Seems the air in the head-space of the bottle is the enemy (and/or auto-syphon valve bubbles) Anyone tried filling their bottles to the brim? Or using plastic bottles squeezed and filled to brim to allow CO2 fill the head-space?

I haven't but think the squeezing technique might work well with plastic bottles. I've just packaged a batch of a similar brew and used a beer gun to fill the bottles and purge the head space so it'll be interesting to see if the beer still darkens - I also avoided oats and used just flaked barley for the mouthfeel to see if this helps.

£25 get a 5 gallon glass carboy, thats what I use and do co2 transfer and dont suffer from oxidation

Although the Rye Neipa I have fermenting looks like the hulk at the moment. 17G a litre of cryo hops.

Considering cryo hops are supposed to be twice as potent as pellets that's pretty extreme hopping, even by my standards - are they all post boil?

I've decided to bend the styles rules (again) - I've brewed a wheat beer base with a wheat beer yeast and did a 300g dry hop, cascade,galaxy & amarillo. The yeast will stay pretty well suspended giving the cloudy neipa look , but being a wheat beer base you can drink it quick.... wish me luck.. i'm about to try one after 5 days of bottle conditioning. I do purge my BB with co2 but not the bottles! :unsure:

The darkest grain in this beer is MO @ 6EBC (82%) !

The Brulosophy gang discuss this briefly in their latest podcast - they suggest it might be down to rapid oxidation of manganese which is apparently present in high amounts in oats.

And in a lot more detail here:

just tried a sample... colour and cloudiness - good.
good head retention.
aroma - neipa
taste - ipa/pale ale
bitterness - avaerage
aftertaste - mildly astringent with a 'juicy water' finish.

Bitterness is present but NO hops were boiled

I think it is short in tropical taste for an NEIPA. Otherwise it goes down well :thumb:

Would I repeat the recipe? - No, because I want more tropical fruit taste
I would do a similar brew but with Mangrove Jacks's bavarian wheat yeast :nod:

Your right. That is really an impressive dry hop ratio.

The cryo hops are Mosaic and Ekuanot.
Also pellet hops were Citra, Nelson Sauv and Vic Secret.
So yeah, not all cryo but still a bloody big DDH.

You can get some bitterness coming through from the dry hopping charges

 

[Braindead]

I didn't boil any hops either, whirlpool with 1.8g/l Ekuanot Lupulin at 80 degrees to obtain a bitterness of 25 IBU

That's why I asked if they were all post boil - I'd be really interested to know how or what you used to calculate the IBUs from the 80C whirlpool addition. :Cheers:

Thanks - I use beersmith mobile but don't think you can adjust the temp of the steep on this version.

 

[Braindead]

Yes your correct, I think thats a feature that should be updated on beer smith to get a correct IBU on the whirlpool.
I just go off the default setting it provides

Here’s my latest effort. This is 6 days in the bottle after 13 days in the FV. I use a bucket FV and siphon to a bottling bucket before bottle conditioning. So it’s a case of doing what I can to splashing and then hoping for the best.

It’s a pretty bright yellow colour right now and the hop flavour is fresh, will be interesting to see how it changes over the next few weeks (it won’t last long!!). The hopping is a bit 2015, 10g/L in the whirlpool and 12g/L in the dry hop.

Dan they were talking about oxidisation and darkening with NEIPA's on this podcast amongst other related stuff.

 

[Hoddy]

This is my latest NEIPA I made using the new Lallemand dried New England yeast. Purposely a really super pale NEIPA with 1kg of oats in it.

Just kegged it tonight and I’ve paid meticulous attention to the beer having no O2 exposure at all whatsoever. I’ll be really interested to see how that beer conditions and develops.

My Rye Neipa. Only brewed last Tuesday. Looking good and tasting better.
FU LHBS for not getting anymore cryo hops

That might be the most glass of juice like homebrew NEIPA I’ve ever seen, nice one!
