With 200 Billion Yeast Cells per pack, the Giga Yeast Gold Pitch features nearly double the cell count of other liquid yeast producers. This equals faster starts, better flavors, and more insurance that your beer is going to turn out well. Double the yeast for just a little more money.  Smart brewing.

The NorCal Ale #1 Strain
Clean Fermenting, versatile strain from one of the most famous California Pale Ales.  Neutral flavor profile creates a crisp beer and allows hops to shine.  Strong attenuator and good flocculation perfectly suited for a large variety of styles.  Good choice for high gravity beers.

More On Cell Count
200 Billion cells per pouch means that with one pounch you can attain the gold standard of pitch count. The ideal pitch rate is .75 million yeast cells for every milliter of wort  times degrees plato for nearly any beer you will make. 200 billion yeast cells is also fantastic if you are making 5 gallons of high gravity beer and don't have time to make a starter.  Saves money if you are making 10 gallons and only want to buy one yeast. Getting twice as many cells per pack versus the other brands is also a great idea for mail order shipment, which can be a little tough on liquid yeast.


Attenuation Medium Gravity*:  76% – 80%
Attenuation High Gravity*: 78% – 80%  (10.5% – 11.0% ABV)
Temperature Range†:  64˚F – 77˚F
Flocculation:  Medium

Style Uses:

  • India Pale Ale
  • Pale Ale
  • Barley Wine
  • Stout
  • Bitter
  • ESB

* Attenuation was measured after 8 days with Ale yeast at 70˚F and Lager yeast at 50˚F.  Medium Gravity is 14˚ – 16˚Plato.  High Gravity is 23˚- 25˚Plato.

†  The working temperature range represents the range at which fermentation for a given strain produces a typical attenuation- not necessarily the ideal temperature for your particular beer style.  As a rule of thumb, start ale yeast fermentation at 68˚ – 72˚F and then lower or raise temp as desired.  Lager Yeast are typically fermented at 45˚ – 58˚F.  If desired, Lager Yeast can be given a “hot start” at 65-68˚F and then lowered to the primary temperature after active fermentation begins (10-20hrs).


For best results we always recommend ordering an ice pack with your liquid yeast.

Just not sure at this point what I think! The wart only perked for a day, it is a stout , so once I bottle, I will not know for 6mo.

Will keep using it for my IPA’s
Finish was a little too dry but one pouch fermented 12 gallons of a 1.062 gravity very quickly.

This yeast loved my double IPA! Will absolutely use again!
First time with the Norcal. Tried the Vermont but had issues with unreliability.

I made a quick starter while I brewed and this stuff took off so furiously it blew the airlock full of foam within 14 hrs!

The beer is a Pliney style double, it is just about done and tastes amazing. Will be a solid %8.

watch the date on your yeast
i'm not blaming the yeast here, just mind the date on the package.
I got one with date November 21st (arrived at my house around Feb. 1st).
I emailed gigayeast and they said use it within 3 months otherwise get a starter going. I chose to pitch it yesterday without starter because i'm lazy (that makes it around 2 months and 3 weeks old). So far it seems like i made a bad decision and i'm gonna need some backup yeast.

Good, but.....
The yeast itself seems to be chugging away just fine but I was disappointed by the age of the yeast. I had gotten the gigayeast due to it's higher cell count. While Morebeer does a great job in turning over the White labs it seems this moves slower. My White labs kolsh yeast was only about a week old while this NorCal 1 was almost 3 months old. According to Beersmith that made about a 48% viability which essentially made it equal to White labs at a higher cost.

Direct pitch into a 5 gallon batch. I'm not overly concerned about a slower start but this yeast finished nice and clean. Nor Cal is the way to go for a reliable house strain.

I wanted to leave an honest review of this yeast. Sadly it's been 37 hours since pitching in a 1.065 IPA and there is no activity whatsoever. Not even a slight krausen like it would if it was aslow starter. Temp has held steady at 67 since pitching. I have never had a lag this long when pitching 200 billion cells. Either this package was subjected to heat high enough to kill virtually all the cells or their claimed cell count is WAY off. I will not be using Gigayeast again.

Slow starter
I made a 1L starter for this yeast to be pitched in 5 gallons of 1.060 beer. It was about 48 hours before I saw any fermentation starting. This is the slowest I have seen with making a starter. I have the ferm chamber set at 68*F. I have yet to taste the finished product, but I wanted to let others know about the lag time so they don't worry about dead yeast. Hope this helps. I will update after the fermentation is complete.

Giga yeast
Second 10 gal. batch with this excellent strain. No starter just pitched one pack with a little yeast nutrient. Starting gravity of 1.063 fermented down to 1.06 in four days! Best yeast ever and I've been brewing since 1992.
