First kits for a couple of years, I’m back on it! Started these today, Mangrove Jacks Pink Grapefruit IPA and a Festival Razorback IPA, going to throw a few extra hops in both just to liven them up a bit more.
 
So it’s been pretty much 24 hours since I added the yeast and the Razorback is bubbling away like a good’n, has been nearly all day, the Mangrove Jacks Pink Grapefruit however, nothing...literally nothing, I lifted the lid earlier and gave it a good stir to try and help activate it but no movement in the airlock at all. Any ideas? Guessing there’s either an air leak but I don’t think that’s the case or the yeast is no good, would it harm it to add another sachet of yeast if there’s still nothing by tomorrow? ‍
 
I assume you've used M44 yeast in the Mangrove Jacks Pink Grapefruit IPA, this yeast is always slow to get going, give it another day or two and hopefully you'll see the all important air bubbles athumb..
 
Would be interesting to see what you think on the beerworks Presidents Sierra American pale ale from love brewing.
The two you've got going have been my go to whenever I've not had the time for a full brew day but that beerworks kit blew me away. Would highly recommend it

Cheers. Tom

I did do that kit a couple of years ago, I’ve actually got the double American IPA of theirs being delivered this week so that’ll be next!
 
So, 3 days in and still nothing from the Mangrove Jacks...‍:?:
Would look at the seal of your lid or whether the yeast was shot from get go.

Couple of options...

1) Open lid and look inside to see potential krausen. Sure sign of yeast activity.

2) Give it a right good stir. Make as much splashing and noise as you can, it'll only help matters.

3) Re-pitch viable and healthy yeast. i.e. buy new and avoid using any of your existing stock.

Good luck with the brew buddyathumb..
 
Thanks Ghillie, I gave it a good old stir after 24 hours, there is Krausen as I can see it through the side of the fv , just no airlock activity.
Just spoken to the local expert in the homebrew shop and he reckons I must have an air leak on the rubber surrounding the airlock, said as long as there’s Krausen the yeast is doing its job so panic stations over! o_Owink...

I did an American IPA from Mangrove Jacks using M44 yeast last weekend and that took over 2 days to start, glad you have found the possible cause, happy brewing
 
I have re-hydrated yeast but have never made a starter, new members may find this of use -



A yeast starter insures you have healthy and already multiplying cells ready to go once pitched into your wort it shortens lag time for fermentation to begin and a less stressed yeast.

Rehydrating is less involved your cell count is smaller than a starter much like a smack pack.

Hi Banbeer/Chippy

In the context of this thread (Beerlover was making beer from kits, using dried yeast) it's a little dangerous to talk about rehydrating and making starters as if they were alternative techniques ... like "VikeMan" says in the forum thread Chippy linked to ...
VikeMan on Beeradvocate forum said:
Most(?) Dry Yeast manufacturers do not recommend making starters with dry yeast. That's fine, but with some worts, you'll need more than one pack ... link to original post
... generally speaking it's safer to recognise that ...
  • Rehydrating is for those using dry-yeast,
  • Making Starters is for those dealing with liquid yeast (whether bought in a vial/pack or collected as slurry/top-cropped from a ferment) :?:

In practice, it would be really difficult to grow more cells than are already in a pack of dried yeast, anyway ... in order to get the cell population to start multiplying you'd need to pitch the average pack into at least 4-5 lts of 1.040 starter wort (anything less than that and the yeast wouldn't reproduce, the cell density would already be so high they'd just get on with fermenting whatever you'd put them in) ... and to grow the population significantly (enough to start doing things like pitching yeast from one pack into two brews ... like Beerlover may have needed) you'd need more like a 10 ltr starter ... in that sense, the only "sensible" way to to do anything like making a starter with dried yeast, is what brewers do when they might use a pack of yeast to ferment a smaller beer (say a Bitter) to grow enough yeast to pitch into a bigger beer (a Barley Wine, say) :?:

Cheers, PhilB
