Dry hopped. Fermentation starting to rocket

[stephen1546]

Added hops to my double IPA kit on Thursday when SG hovered about the 1008 mark for a couple of days.

Checked it just now and it's now at 1004. Any ideas on how its now fermenting more vigorously?

Thanks

What's the expected fg of the kit?

I wouldn’t say dropping from 1.008 to 1.004 is indicative of vigorous fermentation.

Depends how long it was sat at 1.008 for, it may well have had a little bit of fermenting out to go. Also there’s discrepancy in temperature at time of taking a reading and also human error on reading the hydrometer.

I would say 1.008 is pretty mad dry for a DIPA anyhow, 1.004 even more so.

Agree with @Clint, what is the expected FG? Would be very surprised if it was sub 1.012.

Young's kits expected fg is around 1006..

What’s OG?

Mine was 1056...bang on.

Just kegged an APA this evening which had a Starting gravity of 1.052 with down to 1.010 after 7 days with CML US pale ale yeast.
Dry hopped with 75g of mixed hops and kicked off in the bubbler which had stopped 3 days earlier.Checked final gravity today and was at 1.006.
It is known that hops can restart fermentation.
Forced carved at 40psi for 5 mins earlier and now sitting at 12psi serving pressure so I can try a cheeky pint once I get home.

Really interesting that!

Its an Evil Dog double IPA , think its supposed to come out at around 1008, started at 1062

Hop leaf or pellets? Might be wild yeast on them? I had a similar problem last year. Finished beer's were brilliant though. Brewlab found wild yeast in the sample I sent, but thankfully not pathogenic!

 

[Bobtheblob]

How much does Brewlab charge for the analysis?

 

[Druncan]

Apologies to @stephen1546 (the O/P,,) this is not a wild yeasty highjack!

Depends on the range of the analysis. I get HMRC, OG, FG, wild yeast and bacteria/Hygiene usually about £100 x 2 P/A. I post 300ml of finished beer in a sterile sampling bottle. Analysis only takes a few days usually. This may seem expensive, but if you sell your beer it's kinda essential IMHO
I am then a little bit more confident I won't poison someone:tinhat:

I added dry hops to my bad cat kit Sunday afternoon in a secondary fermenter with tap on. Noticed today when I got home the lid was bowed a bit. So just eased the lid up a little to let the pressure out. Also wondered what this was.
