About Me

Hello, my name is Kristoffer Krogerus.
Here you’ll find my random thoughts on homebrewing and beer.
The blog began as a collection of my beer reviews, but now it has turned more into a collection of my homebrewing adventures.

Some facts about me:

  • I graduated as a Master of Science in Biotechnology from Aalto University (Espoo/Helsinki) in 2013.
  • I wrote my Master’s Thesis at the PBL Brewing Laboratory at VTT.
  • I’m currently working at VTT as a researcher and PhD student, researching brewing yeast hybrid physiology.
  • I’ve also done a lot of research on diacetyl formation and removal.
  • My favorite beer styles are IPAs, IIPAs and Imperial Stouts.
  • I like photography.
  • I like DIY (do-it-yourself).
  • I have an awesome and supporting wife
  • We have two cats.


  1. Hi there, I wanted to reach out to you with a suggestion for content on your site:

    I am promoting this visual guide to homebrewing and, after seeing your link earlier to Homebrew Finds, I thought your readers might enjoy this post.

    If you decide to share, all I ask is that you credit the source and I can send visitors to your site as a thank-you if you are interested.

  2. Curious to hear how the beer brewed with eubanyanus tasted. Email me!

  3. Hey buddy, wanted to let you know someone is using your Heady Topper pic on their blog:


  4. hey kristoffer-

    any chance you might be interested in hybridizing a lager yeast? im opening a lager brewery in san francisco next year. we use wlp940. its great for my india pale lager, red lager, black, amber/malty, etc. but for the pils it just puts out a little too much in the way of fruity esters. it also eats up hop oils, makes it hard to do really hoppy pils and IPL.

    my thought is that if we could cross it with “american” pilsner yeasts, hopefully we could tone down some of 940s fruitiness, while making it less hop-hungry like the american lager yeasts.


  5. Hi Ant! Thanks for the interest and the offer. Unfortunately it would be a little tricky creating a cross between two lager strains, since they are already hybrids themselves. It probably wouldn’t be impossible to create such a cross, but I don’t think it would be worth the effort, time and resources. Rather, you might have more success trying out some more of the lager strains out there. What would be easier to do though is cross an ale strain with a lager strain, or the easiest option would be to cross two ale strains. But I guess that is not something you are interested in. Feel free to contact me at first name dot surname at gmail if you have any further questions.


  6. I would like to follow your blog but cannot find a link. ???

  7. Hi Dr. Kristoffer,

    my name is Fábio and I also work with brewing yeast. Our group has been isolating yeast from cachaça (sugarcane spirit) production vats in Brazil, and we are using them in beer. I am very curious about your Conan hybrid, will you be sharing the yeast strain or intend to keep it for research purposes only?

  8. Sorry, I don’t have any link for following the blog. Here is the RSS feed in case it is of any help:

  9. Hi Fabio,
    I’ll definitely share the strains once I’m done testing them (later during the spring)! 🙂


  10. I created the retappd wordpress plugin that you have been using on your website. Would you consider rating or writing a review for the retappd wordpress plugin?


  11. Hey! Found you from the forums. If you are selling that conan hybrid yeast, sign me up! I would love to buy a sample.

  12. Hi,
    I grow up and send out the Conan x WLP644 hybrid every now and then. Keep an eye on the forum thread on Homebrewtalk for any updates!


  13. I just discovered your fascinating blog. I was in Helsinki in September, and would have bought you a pint if I had read it earlier 😄

  14. Thanks for the kind words! I hope you enjoyed Helsinki! I’ll take you up on that offer if you ever make it back.
