What's up everyone thought I should have a beer it's my Friday night no it's Thursday because I'm brewing tomorrow anyway.
I'm going to show you guys one way that you can reuse your yeast tonight. It's not the only way, maybe not the best way, but you can save five or six dollars a batch if you're just using one time for the next batch you can save a little bit of money. And you're gonna for sure have plenty of yeast for whatever beer that it is that you're brewing. This is what I got on tap right now, a cider Imperial steam beer a pale Rob beer that was kind of something I came up with and then this is actually um made by surly Brewing Company it's their aah a rally Imperial Brown that they gave to us and then we can ferment however we want but uh yeah hopefully by the end of the night.
I'm gonna rack a beer out of the primary and we'll have a nice growler full of these to use you got your Flaming Lips we're going to cover the whole Dark Side of the Moon at Bonnaroo and already been down. You're going to want to boil two to three pints of water for these minutes to get it good and sanitized. Oh, pretty funny huh we're going to use that later in the process and it will have to cool down after this so make sure you do it ahead of time.
Because it's winter here and nice and chilly and good old st. Paul this palace has been degrees. So that means is well after it's been done fermenting for a couple days so as you can see it has a nice compacted a yeast cake which will be good for harvesting.
All right there's a couple things you want to think about when you're gonna be making a batch of beer to use the yeast cake in the next batch for the next two batches you generally want to first of all think of kind of a lighter color to darker. In case you end up making a darker beer first, and you end up harvesting a lot of the beer color – even a little bit of darker color could affect you know that if you're making a lighter beer it could make that a little bit darker than you want. The second thing is you normally want to make your lower gravity beer first, especially if you're going to make like a barley one.
Imperials daughter really big IPA or something you want have a lot of yeast for that so you might make like pale ale or a bitter or just a lower gravity that's like you know a helis or whatever.
First well that's a longer yeast but you know saying you know and then have that yeast for the higher gravity beer in this case. There's even another consideration I'm making two beers that are both about I'm making a helis and a pilsner two lagers. So I made the helis first, because is less hops and I'm final to the hops and the Pilsner so if I used that yeast cake it might have more hop truth. So you know this time I only have one ounce of tops in the helis and then I'm use this yeast cake which will include a little bit of the true in the Pilsner.
So anyway, there's just a few things to think about but yeah it always works for me. And practice good sanitation and you kind of do this method that I knew you're not gonna have any problems I'm getting down there now the way I do it is I try to get as much beer out of the carboy as I can. Especially if I'm going to use the yeast, my thought is I just don't want the beer from this batch mixing with the other batch. I'd rather just have the water which is the water that we boiled and we'll see that in a second it's not a huge deal of course.
I want to get as much beer as you can into your secondary but I use a x under the side of the carboy. Don't know if you can see but it's kind of tipped up yeah, you can see on the left side you can see it's sticking out of there and that just helps me angle it down right here and I don't go too crazy. I don't want to suck up a lot of the yeast for clarity reasons into the secondary.
But now I have another thing going on my carboy, my secondary is actually getting pretty full I had just over five gallon so I pretty much have to pull the plug here just for that reason. But there's only a little bit here that's only actually like three four ounces so that's alright actually I can just keep this rolling let's just keep it rolling.
What we'll do here quick long as we got the thing all live action five I've got my sanitized funnel which we'll use for the pouring and into the growler but we'll also just use it now. Here's the water that's been sitting in a degree room, so it's totally cooled down. You might not need all of it you really what you're doing is you just need enough of it to be able to loosen the yeast on the bottom.
Now this is a I only poured about a pint or so in there so now I'm going to try to swirl it up now. I didn't film it but I've actually been swirling this thing for two, three, or four minutes a little bit. It was really cold so it was really stuck on there of course but uh I actually ended up adding a little more water in there just to make it a little bit easier to get the stuff off the bottom. But it's fine and the amount of yeast I'm collecting here is way way more than I need and I may or may not even pitch all of it. I can't even no yeah that's that's pretty much everything in my primary now.
What will happen is this will Stratus stratify and if you want to what you can do is as it settles the yeast stays on the top I believe you know you can look at my website Don Osborne com I have another example of this in pictures. But believe what happens is the junk stuff you don't want settles out first and the more white stuff will stay on the top.
When you see a couple layers so what you can do is pour that stuff off into another container where you might have dumped a little pre-boil than cold water in. And then what you're doing is you're sort of washing the yeast and making it a little more pure. But basically I'm all set I'm going to cover this with foil and I'm going to put it in the fridge.
I'm going to brew tomorrow and I'll dump you know this is almost a half gallon, so I won't dump this whole thing in there but um you know I'll dump maybe a quarter of this or half of this in there and it'll be just plenty of yeast to ferment basically any beer that you're going to make.
So give it a try save yourself some money reuse yeast and happy brewing to you!
