We strongly recommend ordering dry yeast in the summer months. We do include complimentary Cold Ice Packs with all liquid yeasts. However, it is difficult to guarantee that the ice packs will survive the trip, given transit times and particularly hot temperatures.

Great Yeast
I will definitely be using this yeast again. I used the yeast in an extract batch. I did not use a starter. OG was 1.074. FG was 1.016 after 7 days.

This has got to make the cleanest tasting beer! I've used it twice now with my annual honey basil double pale ale and it really let's the basil and hops stand out nicely. I've ventured off to use different yeasts with different beers, but I always seem to come back to this stuff. Pales, ipas, porters, and stouts, it works in everything...we even made a maple syrup/brown sugar imperial nut brown with it! The flavors were incredible. Do yourself a favor and just add this to your go-to list.

Clear, clear, clear
As it states high flocculation leads to a clear beer. Used a yeast starter, not sure if hot weather was a factor in transit but it didn't have the aggressive/potent characteristics others have reported. The transition and 2nd generation with very limited lag but it has been steady and consistent rather than blow the lid off rapid. Crisp and accentuates hop nuances well.

Great yeast, great customer service
Ordered this yeast and it arrived luke warm. After pitching a starter for 48 hrs, the starter was inactive. I emailed customer service and within a few hours had a response that a free replacement was on its way. The new vial came a few days later, pitched very well with an active fermentation. Terrific yeast - my go to.

They should rename these guys the yeasty boys causing they are tearing it up. Excellent jump start to the primary fermentation.

Good thus far
The batch I used it for isn't ready as of yet but so far it has produced a strong fermentation. Looking forward to using it again in the future.

Works great
Works just as good as the original packaging and is easier to store to save up for whitelabs rewards. My go to strain for everything from ipa to cider.

Is this enough to ferment a 10 gallon batch?
Matt M on Feb 19, 2017
BEST ANSWER: A Single packet of WLP001 (or any other yeast) by itself is not contain enough cells to afequatly ferment 10 gallons of wort. I would recommend pitching the yeadt into a 2 later starter. This will allow the yeast cells to multiply in order to pitch into 10 gallons of wort & ferment properly.
I have had this yeast in the refrigerator for about a year. Could I still use this?
Anthony B on Jan 1, 2017
BEST ANSWER: I wouldn't risk it. It would be smarter to just by a new container of yeast than to risk ruining a whole batch of beer. What is the best by date? Try adding it to some boiled water and DME and see if it's still viable.
Is this enough to ferment a 10 gallons batch?
A shopper on Feb 19, 2017
BEST ANSWER: No, I do a starter, stepping up to three gallons over the week before. Go to White Lab's website, then Home brewing and then select the starter pulldown. Make that starter and then make a 2.5 or 3 gallon wort for that starter and let it finish the week.
Drain the liquid off and pitch the slurry.
My friend is alergic to night shades and is worried there is potatoes in the yeast. Is there?
