Is there a list of big krausen yeasts that tend to require blow off tube?

For quite a while us-05 has been my go to yeast, I get a 2-3 inch krausen, it falls, then that is it. I decided to start trying different yeasts and the last 2 (Juice and K-97) decided that my 1.25 gallons of extra head space in the fermenter was not enough and blew through the airlock. Is there any easy way to tell if a yeast strain will have a high likelihood of climbing out of the fermenter? Is there a list somewhere of these strains? All I could find were threads where strains would be mentioned, but no place with an easy reference. Thanks in advance!

Edit: I have had so many good responses that I edited the list started by Holden Caulfield below to include the other entries so far. As mentioned by u81doughboy below there are several variables that can impact krausen size. This of course is based on anecdotal evidence and meant to give rough guidance on what to expect from a yeast strain. Feel free to comment below and I will adjust as necessary, thanks everyone!

Need a blowoff - a beast that will crawl out of anything...
  • Wyeast 1469 (Timothy Taylor strain)
  • Wyeast 1007 (German ale)
  • WLP530 (Westmalle Strain)
  • WLP540 (Rochefort Strain)
  • SafAle K-97
  • Imperial Yeast A38 Juice
  • Wyeast 1318 London Ale III
  • Voss Kveik
  • Kolsch 2565
  • Lalbrew Verdant IPA
  • Imperial Whiteout
  • Bell's house yeast
Need a blowoff - not like the beasts, but still made it out of my fermenter
  • Wyeast 1272 (American Ale II)
  • WLP 530 Belgian Monastery
  • Wyeast 3522 Belgian Ardennes
No blowoff experienced for my situation, but close (basically all the other ale yeasts)...
  • Nottingham

  • S-05, WLP001
  • S-04
  • WLP007
  • Wyeast 1084, WLP004

  • Wyeast 2278
  • Wyeast 2206
  • WLP833 (Ayinger Strain)
  • WLP800 (Note, this is suppose to be the same as 2001, but genetic testing has show that it is not the same as it is an ale yeast)
  • Wyeast 2001 (Pilsner Urkell H-Strain)
  • Wyeast 2112, WLP810 (California Common)
  • WLP029 (Kolsch)

I haven't seen one, but it's a good idea! If someone starts a list like that, I vote for Bell's house yeast to be on it. I almost never need blowoff tubes, but Bell's yeast blows through my head space every single time. It has the fluffiest krausen I've ever seen.

I've never seen a list like the one you're thinking of. It's probably a good idea although it depends on the type of fermenter you're using, temperature control amongst other variables. Besides the Belgian yeasts (which IMO always require a blow-off) I tend to put a blow-off on all higher gravity brews (1.060+) as a precaution.
Good luck.

Also, as some of the other posters above have alluded, if you've got an aggressive fermentation and your recipe/process created a lot of foam-positive "schtuff," that's obviously going to have a lot of impact, too. So high temps, high protein of appropriate particle size, etc...

Imperial juice yeast is super similar to wyeast London ale but I really like imperial because they advertise 200B cells. The first time I used it I pitched a little warm at 70 and with in 5 hours the air lock was so bonkers I put a blow off tub on. I used it two more times and pitched a little cooler and did not have the same experience. I love this yeast for hazy IPAs

All yeasts! All yeasts should be on that list. Always use a blow-off tube if unless you have ample headspace. A 1:1 relationship between yeast and blow-off is wrong. I think grain bill, gravity, hop quantity, wort nutrient mix, headspace, etc all contribute to blow-off.

Add Imperial Whiteout to the list. 1st pic was 1 hour after pitching into my starter. 2nd pic was the following morning.

Per my experience, below is a list of yeast where you should always use a blowoff and those that I have not had an issue with. Note - I ferment in a SS Brewtech 7 gal Brewbucket with approximately 5.4 gallons of wort so a significant amount of headspace. I also have very good temperature control. Finally, I typically brew beers with OGs < 1.055 except for the Belgian beers. If you have less headspace, ferment at higher temperatures, and brew high gravity beers then you should use a blowoff until you know for sure what is safe for your system and process.

I used K97 for the first time a couple of weeks ago, this was less than 24 hours after pitching yeast in a 7.5G Fermonster. I did rehydrate.

Hooked up a couple of kegs on day 4 to purge Star San out of, and ended up with some gunk in the keg. Heavy hitter for sure.

Thanks for putting this together! I copied and modified the list to add the other entries and added it to the end of my first post on this thread.
