    Yeast mixing is a very interesting topic indeed. Never tried it for myself as of now, but a brewer friend of mine managed to get a very fast - and seemingly not active-looking - fermentation by mixing some products from Fermentis. I recall S-04 and T-58 being used 50/50 but, this being done years ago, I might be wrong on the strains.
    As always, your videos are very informative. They also pushed me over the edge and I just ordered a brand new Grainfather unit to replace my problematic Brewmonk. Many thanks for that ! :D

    Interesting video, I've come back to home brewing after a long break(25 years). I used to do a bit of all grain brewing. I didn't even know that co fermentation was a thing ! And I didn't know about pressure fermentation.I've only been using mangrove jack's kits for the last year experimenting with a fermzilla. But I've been thinking about mixing a couple of mangrove jack's yeasts in my next kit brew. So after googling I found your video.
    My next brew was going to be mangrove jack's American pale ale, it comes with empire ale yeast M15, and I was thinking of mixing it with M42 with the aim of getting higher attenuation. Your video has given me the confidence to give it a go! Many thanks 👌🍺

    Hi David. Great video! I'm doing a 12% porter soon. I want the flavour profile of 1968 and was thinking of finishing with Nottingham. Any advice on pitch rates for both and when to pitch the Nottingham? Thanks

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  4 роки тому +1

      Thank you. I have not tried this mix and as such experimentation is key. Here are some initial thoughts. Because Nottingham is a neutral yeast I would have no concerns in pitching it early. So your first test could involve pitching both for a combined pitch rate. I would look to a pitch calculator for each as use that to guide a collective pitch as a blend. I would test this with a small batch first.

    Thank you for this introduction into another mysterious and rewarding subject!
    I brew extract kits and have been riding the learning curve after 20+ batches in 6 months.
    Now, I am using the canned extract kits as a base and adding boiling water and hops to simulate a boil.
    At the "flame out", i.e. add cold water to pitching temp, I add more hops.
    Experimenting with yeast combinations and timing is part of the trials and tribulations.
    I look forward to be able to add more customization to my future brewing AND going all-in-one with a BrewZilla.
    Can you suggest a yeast combination (I know you have umpteen possible combinations in your arsenal...) that would marry well with Coopers IPA Kit hopped with Columbus at 30 min and Cascade at Flame out? Sadly, I have no idea what variety of yeast comes with the kit.
    Happy brewing from Riverview, New Brunswick, Canada!

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  3 роки тому +3

      Hi William, yes it is great to experiment. Cofermentation is very much part of this. For your IPA you could try a blend of British yeast for fruity esters and American yeast to make for a more dry result. So fermentis S04 plus US05 for example. This combination is used a lot in commercial brews.

  • @sebastianmaestri6653
    @sebastianmaestri6653 3 роки тому +1

    Hi David, great video as always. Have you tried the combination between a less flocculant belgian strain (like Belle Saison of Lallemand) and Nottingham to help flocculation? My question is regarding the temperature, as I will raise it up to 27°C and I don't know if Nottingham will work well at such temps. Thanks!

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  3 роки тому

      Yes, certainly. In fact I have a follow up video planned quite soon that runs through pairings like this in more detail, with commercial beer examples. Just be sure to keep temps within the range that both yeast can handle.

    • @sebastianmaestri6653
      @sebastianmaestri6653 3 роки тому +1

      Thanks for your answer! Nottingham goes yo to 21/22°C, so maybe I should avoid going to 27°C. So, regarding a saison profile, what do you think would be better, two packets of Belle Saison (3 days at 20°C then rise to 27) or Belle Saison+Nottingham one packet each (20°C all time)?

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  3 роки тому +1

      Yes, I would stay within 20-21. One packet of each should suffice when pitched at the start. This is assuming that you are under OG 1,060.

  • @mikef9609
    @mikef9609 3 роки тому +1

    Thanks David for your all your hard work on this channel, your videos are one of the highlights of my week.
    I have just laid down a Saison and have used WLP565 as well as Lallemand Voss Kveik. This is the first time I've used Kveik and wow, I cant believe how fast it is fermenting. Its amazing.
    2 Questions though.
    1. Will the fermenting speed/aggressiveness of the Kveik yeast interfere with the ester profile and characteristics of the Saison yeast that I love?
    2. I am planning on following on with 2 further saisons, a Rye and a dark re-using the yeast cake from the initial batch. Other than oxygenation can you see any issues with this? I was thinking of cell counts.
    With thanks

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  3 роки тому

      Great to hear Mike, thank you :)
      1) Kveik ferments slower at lower temperatures. You can expect a yeast to put it's flavour and aroma signature down in the first four days. So as long as it is given this amount of time then you should be fine. You can also pitch your flavour yeast first to give it ahead start when you wish to use higher temps.
      2) This will be fine, unless you have gone high gravity.

    • @mikef9609
      @mikef9609 3 роки тому +1

      Just an update. Both the original saisons are wonderful, I especially like the mouthfeel and new character the kviek adds. I also have the tripel conditioning with a week to go, cant wait. Quick question, Im planning to do your Belgian Blonde Ale with Kviek. Would it be prudent to reduce the amount of orange peel due to the orange/citrus character in the kviek? Also would a months conditioning aka, the Tripel, be appropriate.
      With thanks.

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  3 роки тому

    David Heath, how would Voss work with a Belgian diastatic yeast like MJ's M31/M41 work? I brewed your recipe for Belgian golden (or was it the tripel?) mashed at high temps, 69C, with M31 and it kept on bubbling in secondary (very) slowly for more than 3 months (at 17-ish C). How would Voss or Skare help reduce that time given that they're not diastaticus like the M31?

  • @pantseilmari8151
    @pantseilmari8151 3 роки тому +1

    I'd like to try my first wee heavy. Do you think a strong Scotch Ale would benefit from co-fermentation? Also; why does kveik cut down the conditioning time for example Belgian beers from 6-12 months to just a couple of months? What is the science behind it? I can't wrap my head around it..

    • @DavidHeathHomebrew

    Hi David. You say mixing lager yeast and high temp ale yeast is something to avoid. I have a thought though. What about say 34/70 mixed with lutra at say 20c under pressure? Would this work? Would it condition faster and would I still have to lager it?

    Hi David, what if you want high abv% with benefitial aroma and flavors? I am sure you can guess why I am exploring this.... Process wise, would you still pitch both yeast at same time if you are aiming 16% ABV? Would pitch EC-1118 at high gravity and once SG reaches Lallemand Verdant recommended OG, you pitch the second yeast?

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  3 роки тому +2

      Hi Jacob, In this case pitch your flavour yeast at the start. As long as you can ferment for 4 days then you can pitch your more alcohol tolerant yeast at the same time or a little later. I prefer a co pitch usually.

    Pitch rate??? I want to co-ferment a beer with WPL013 (Pure Pitch) and verdant. The calculators tell me I need 4 packages (1.064 OG).........sounds like too much to me. If I want to use one package of each yeast, can I make a 2L starter and combine both packages in the same starter? Or are the 2 original yeast packs enough?

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  4 місяці тому

      It really depends on the volume but many calcs raise the rate after 1,060. If this is a one keg batch then I would go one of each and feel that would cover it very well.

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  4 роки тому +5

      This can certainly vary and for the best results you may wish to run some trials first. One example I can give would be S-04 and US05. These work nicely when both pitched from the start. This is due to US05 being a neutral yeast, so there are no flavours that could be added to concern yourself with and you will gain its attenuation rate alongside the fruity esters from S-04.

    • @DavidHeathHomebrew
      @DavidHeathHomebrew  4 роки тому +4

      Not really no. If you pitch 2 yeast at the same time at the same ratio then this ratio will be true for the first brew. However, mutation will creep in gradually with more generations of re culturing and the ratio will shift. If a strain becomes weak then it could die out but this will only occur over a more lengthy time period, depending on the strain.
