Description

A09 Pub is a highly sought after strain that home brewers swear by due to is ability to achieve brilliantly bright ales in a short amount of time. Because Pub is extremely flocculent it will tear through fermentation and drop out of your beer quickly. This strain will produce higher levels of esters than most ale strains. A sufficient diacetyl rest is highly recommended when using A09 Pub.

Good amount
Required a smaller starter than the others. Fermentation started quickly once pitched.

Love It
Use in Low Gravity English ales works great. Fast ferment and easy to harvest.

A Real Workhorse
I have used this yeast at least three times. It is very aggressive, takes off like a race horse, and finishes very quickly. For every beer with this strain, I have done a diacetyl rest, raising the temperature 3-4?_F to take care of the very junior-young-green flavors. This always did the trick.

I would also agree with the other reviewer about the can. The yeast does stick in the can. The best bet is to warm the can up a bit (I know, I think it says pitch cold), give it a good shake, and the pour. Those of you who have had experience with the older White Labs tubes will know how yeast can get a little caked if it is sitting long. I think this yeast is similar, particularly if it has been sitting idle for a few months.

Disappointing
For a first attempt at using an Imperial yeast, I decided to pair the Pub with a Honey Blonde Ale I was creating. The entire brew and fermentation stages worked out without any problems but the resulting ale has off flavors and a disappointing taste. I won't completely write off Imperial but it'll be awhile before I try another experiment with their yeast.

Worked as described
I have a Wee Heavy, finishing in secondary, that I used this yeast for. Probably not a good style choice for this beer but so be it. The OG of 1.098 came out of primary at 1.025 after 6 days so not a bad performance so far. It flocs very well and racked almost perfectly clear.
Only bad mark I can say was when I opened it, cold and well shaken, the yeast was caked and stuck on the cans bottom and had to be scooped out with my finger. Worried me a bit but my hands had been wet with Star San and no evidence of buggies so far.
I am doing an ESB with it next, and will update you as to the Wee Heavy's progress and the ESB.

Response from MoreFlavor
The wee heavy has drawn raves from friends and the British ale I brewed next is one my better ales thus far.
I highly recommend this strain and will be ordering more for sure!
BTW....the 2nd can behaved well, and fermented a 10.5 gallon batch in my Speidel with just the one can!
