bottled 90 min ipa clone, weird.

[olz431]

So I tried a bottle after a week of a 90 min ipa clone. The first bottle smelled and tasted of bananas and was flat, I grabbed another that was carbed and had no hint of banana. It got hot during fermentation for a few hours but got it under control. Did I have an infected bottle? Did i not get the pruning solution mixed in? I used 4 oz of corn sugar in about 4.5 gallons of beer. I had another flat one a few days ago and there was no hint of banana at all......
Before bottling it tasted great as does this carbed bottle I am drinking now. I used nottingham yeast.

BTW all of the botles were thoroughly rinsed, then soaked in a strong solution of starsan for 20+ minutes as well as the bottle caps.

How hot? How long?

 

[olz431]

65-68, a week tomorrow for in the bottles. It got up to 80 during the ferment for 5 or less hours. The pre bottling sample had no hint of bananers.
The ferment other than the hot period was 65-68.

The smell of bananas was Probibly caused by isoamyl acetate - a chemical that is produced in limited amounts in fermentation of hefeweizens. That one bottle I would guess was not sanitary enough ( for what ever reason) . As for the sporatic carbonation - how did your fermentation go overall? Aside from it got a little hot- how was your lag time? How does your cake look? Did fermentation get going off to a good start& then stall out? What's your finishing gravity ?

I ask questions , because I have had similar problems , and just want to narrow my answers a little .

 

[olz431]

Fermentation was extremely violent and had less than 6-10 hour lag time, went from 082 to 011 or 10 in less than 7 days. I dry hopped with 4 oz. The only hint of banana was in 1 of 3 bottles this far. Maybe I should grab another to see how widespread this is?

 

[olz431]

And the cake was uniform and looked pretty compact.

 

[olz431]

Just cracked open another an no banana at all, slightly carbed but far from ready. These beers aren't easy to sample a bunch of let me te you that.
BTW I racked this into the secondary to clear it, also used 5-8 drops of biofine, I'm trying to think of everything.

Yeah do go through the lot and see which ones didn't carb up right. In general, I give my beers at least 2 weeks to bottle condition ( sours and Saisons I give at least a month), I have noticed you will see inconsistencies in carbonation before allowing a proper amount of time to condition .

Other then that - I would say the inconsistencies may be due to sanitation. Also, I like to turn my priming sugar into a simple syrup- just mix it with a small amount of water ( enough to barely wet it ) , boil for 5 minutes and cool- then add that to your bottling bucket . I find consistency from bottle to bottle to be a lot better .

Hope the best! Cheers to beers !

Also - be cautious of how strong of star San you use in bottling: I find 5ml/gallon is more then sufficient . If its too strong , it can kill what yeast may be left so carbonation can be less due to that.

 

[olz431]

Yeah I boiled the sugar before mixing it into the bottling bucket. I wish I could wait 2 weeks!

 

[olz431]

For the bottles I use probably an oz to 7-8 gallons in the water since I soak probably around a half hour.

Not to change the subject but where did you get the clone recipe? I want to try brewing this next.

 

[olz431]

It's in the recipe section near the top of the ipa section, the hops are spot on, I'm waiting for carbonatiob to check the taste.

 

[Blinebuddy]

Sounds about right . Well, if anything it may just be due to variance in sanitation from bottle to bottle . I'd wait it out - time will help with carbonation and consistency . The number one fail safe rule of odd , or different beers is to set them aside and come back to them.

Found it but damn, it's an AG recipe.

Bansheerider, I had a handfull of yamaha rds, one wicked ported by motocarrera long rod 400 with 36mm flatslides and milled jugs, 028" squish, 78 HP on a 275lb bike, two strokes are hard to handle, all grain brewing is not. I also had a piped h1 triple

Haha good to know. The price of equipment is keeps me from AG for now. I just dumped a bunch of money in a mini fridge conversion to kegerator and all new kegging equipment. Although the price to beef up banshees is not cheap either.

If you buy a rubbermaid 10 gal cooler and a pot big enough for full boils I will send u a brass valve, chunk of brass pipe, stainless washers and a t with fittings to attatch a stainless toilet supply line mesh to just because I can get the stuff cheaper than dirt. Pm if you want to go all grain.

Thanks for the offer, I'll keep that in mind. I saw a recipe for an extract 60 min IPA and it says to boil the extract for 60 min. What would happen if I added 6 out of the 9 pounds of LME at flame out for this recipe?

 

[olz431]

I do not know, I have no experimentation with extract as I have only done one batch.

That's actually the preferred method. It keeps the DME/LME from caramelizing during the boil, making for a lower SRM, plus you get better hops alpha acid conversion from the lower gravity.

I do extracts with partial mashes and before I joined this forum I used to add all the DME at the beginning and my beers always were darker than they should have been. l also think the longer extract boil creates more unfermentables which in turn maybe responsible for my beers always having had a higher FG than calculated.

Looking into AG now.
