  • OYL-400 is an Omega Yeast original and makes an incredible choice for pastry stouts, milkshake IPAs and other modern ales
  • Ripe banana esters with a hint of pear. Bananza® descended from a Hefe strain but produces zero clove flavor
  • Double pitch size with a minimum of 225 billion cells—twice the size of the standard yeast pitch
  • Proprietary propagation methods generate fresh, metabolically strong yeast cells and optimal biomass
  • Omega Yeast is founded on curiosity and innovation, expertly producing common workhorse varieties and many unique strains

Love the banana character of Hefe yeast, but hate the spicy cloves? Omega's Bananza yeast is exactly what you're looking for. Descended from a Hefeweizen strain, Bananza was developed to be non-phenolic and therefore incapable of producing clove flavors that would mask its pure banana profile. Dripping with ripe banana esters (with a hint of pear), this Omega Yeast original is perfect for pastry stouts, milkshake IPAs, and other modern ales.

Attenuation: 73-77%
Flocculation: Low
Alcohol Tolerance: 10% ABV
Optimum Fermentation Temp: 64-75°F
Cell Count: 225 Billion
Strain Type: Ale

Please Note: For best results we Always recommend ordering an Ice Pack with your liquid yeast. Ice Packs can be found below in the "You might Also Need" section.

Available only in the US and Canada. While we would love to make these strains available internationally, many countries regulations do not yet allow the sale of organisms developed using modern gene-editing, regardless of the type of modification introduced by the technique. Please feel free to contact us for more information!

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Great yeast.
I wanted to make something different and made a Banana Milkshake IPA. This yeast provided some really nice tropical flavors, banana and coconut especially
Beer came out nice.

Great fermentation, but sadly no banana
I used this with rather mixed results. Per Brewfather recommendations, I made a .8 liter starter. It started fast and fermented strong once pitched, which was great. My one issue with it is the fact that I got zero banana aroma or flavor from it. I pitched at 67 and let rise to 72, pretty much per the instructions on the package. That said, this was kind of an experiment. I used this yeast in a porter, along with some spices to make a banana bread porter as a holiday beer. I will absolutely try it again in a simple wheat beer and will more fairly judge it in that application. So, three stars for a great fermentation but withholding more pending better banana results on the next attempt.

Banana Bomb!
Banana flavor is over the top, which is what I was going for. No clove whatsoever, as advertised. Brewed/mashed for banana forward Hefeweizen (I.e., 70% German wheat, 30% German Pils, high (1.063) OG to stress yeast and create esters, 1.016 FG, no acid rest, mash-in/protein rest @ 130F for 10, Maltose rest @145F for 35, Sacch rest @ 161F for 30 and mash out @ 170 for 10 to help with the lauter). I BIAB, so I brewed a larger batch than normal and let it settle overnight in the kettle after the boil before transferring to allow the sediment to drop and transferred only clear wort to the fermenter. I've found that clear wort is key with Hefeweizens and Belgians that derive much of their flavor from the yeast. Made a 1L starter and pitched at 68F with no aeration, let the temp rise naturally to 75F and held until finished. As is typical for Hefe yeasts, this one did generate quite a bit of sulfur, so I gave the beer a stir 2 times 24 hours apart starting around day 3 post-pitching. Went grain to keg in 6 days. No sulfur in the finished brew. Got lots of compliments on this one.

No flavor contribution at all from the yeast...
No banana flavor at all from this yeast. I pitched at 70F and let rise to 75F over a day, temperature controlled. No esters at all. Was hoping for a nice Hefeweizen for the summer, but I got a flavorless, 4.8%ABV wheat beer instead. The yeast did ferment super dry and fast. For a beer mashed at 154F, the FG was 1.006 in three days.

Great banana, ferment warm!
I am on 3rd gen of this yeast. It made great beers that blew my taste buds away, and those of my guest. I made a NEIPA, and served it to multiple people and they asked if I put bananas in the beer. It definitely works but I contacted Omega and they said to definitely ferment warmer.
