Question on IPA's yeast scavenging.
Re: Question on IPA's yeast scavenging.
I love IPA's harvesting method. It's just so easy at all stages. I use a turkey baster and 250ml pop bottles. I then use the harvested yeast for 500ml starters for 10L brew lengths
Re: Question on IPA's yeast scavenging.
Glad to see you find it simple. Your avatar does make me smile. I am guessing your name is Michael MyQul. Just google "cul" in French and you will see why I smile.

Yes, my name is Michael. Ah, I see why you would find it amusing, especially as you're France based. But it only really works is you mix english and french as 'my' in French is 'Mon'

Re: Question on IPA's yeast scavenging.
My 250ml bottle has a tiny amount of yeast after several days, maybe 5ml tops. Is that enough for a starter for a 10l brew?
Re: Question on IPA's yeast scavenging.
Yes. What you have sounds exactly like what I get for my 10L brews. IPA says he harvests using a 500ml bttle and pitches into 1L for a 50L brew. Based on that pitching what you have into 500ml of starter wort should be enough. But I've always chickened out and put it into a 1L starter. I'll be pitching on tues, so am starting my starter today. I plan on 'manning up' and just using 500ml. I think it should be plenty though seeing as my OG will only be 1.036Paddington wrote: ↑Sat Nov 25, 2017 11:15 pmMy 250ml bottle has a tiny amount of yeast after several days, maybe 5ml tops.

Thanks. I'm another Michael and, despite my A level in French, I was unaware of the alternative meaning of cul.MyQul wrote: ↑Sun Nov 26, 2017 11:49 amYes.

Re: Question on IPA's yeast scavenging.
I've got my first harvest sat in a 500ml bottle right now. It's WLP007. I used a turkey baster, and made sure to catch some of the bottom of the kraeusen too - I can only think this is a good idea, to boost the yeast content, while still having it safely tucked away in the beer. Looks like I got plenty.
I would say the downside of the method is that you still have to make a starter, whereas enough pure yeast (top or bottom) collected from a previous brew can start the next one without, and I have a friend who does that routinely with yeast that is a couple of months old. The main benefits seem to be the particularly easy harvest of very fresh, active yeast; the easier temperature handling, perhaps, with the beer-protected harvest being less prone to shock; the longevity of the sample.

Re: Question on IPA's yeast scavenging.
I’ve not considered saving yeast but reading these posts I’m going to try it. How is the yeast stored after harvesting, in the fridge ?
Re: Question on IPA's yeast scavenging.
A quick update. I now use one of these with a short piece of silicone hose attached to the nozzle to take the sample of wort. It may look expensive but it is only 1.5 times the price of commercial liquid yeast.

Excellent..and it appears you can also use it to wash your..errr... ears as well!IPA wrote: ↑Tue Dec 19, 2017 2:02 pmA quick update.

I think there’s already a thread going on Whacky Beers. This could be the winning ticket...oz11 wrote: https://www.amazon.co.uk/Syringe-200-ml ... l+jonplast

Re: Question on IPA's yeast scavenging.
A bit of bump on this. I've now got a 3rd generation brew going with some WLP007 scavenged this way and, like the second generation, it's going really well.
I'm starting to wonder if I should take two (or more) harvests from the current batch, before it mutates down the line too much, storing one or two to come back to. I could have done that last time, I guess. Has anyone done this method enough to spot any characteristic shift in how it changes a strain by selection, versus plain top or bottom selection? I know it's more of a top-harvest than anything, but with plenty of activity in the beer 36/48hrs into the brew when we a re harvesting, I guess we are getting a slightly different mix.
Also, I think it may be useful to readers of this thread if there were a link to the method itself in one of the top posts! I'm not sure where it is, now...

Anyone harvested lager yeast using this method?
