Excellent Yeast
I couldn't find this yeast locally so I ordered it from Northern Brewer and am very happy with the performance. I originally bought it for a Wee Heavy and decided to make a Brown (similar to Scottish 80/- but with US 2-row) as a yeast starter for my Wee Heavy. It fermented extremely clean and has an awesome smokey flavor with kettle to glass in 16 days using a keg to force carbonate. The Wee Heavy is going nuts in the carboy, yeast took off in less than 8 hours @ 57 degrees... Can't wait to see how it comes out in a few months.

I used this yeast with the Bourbon Barrel extract kit and was very pleased with the results. I prepared it with a yeast starter 24 hours prior to pitching and the yeast has been bubbling for the last couple days. I plan to use this yeast again.

Very active yeast!
This was my first time using a Wyeast smack pack. The packet inflated as expected but I had to figure out a good way to break the inner packet. What I didn't realize is that the thing is sealed so well that I didn't have to be so gentle with it! It made for such an active yeast starter that I was afraid to go with a bubbler lock into the primary fermenter. That turned out to be a good choice. Extremely active fermentation that blew off so much I had a thick yeast cake in my sanitizer bucket. After four days, I removed the blow off tube and replaced with the bubbler lock. I just transferred over to secondary and the imperial stout is looking, tasting, and testing great so far!

Great customer Service
I bought this pack for the bourbon porter. The day before brew day I smacked the pack and waited. After 24 hours the pack had not inflated, so I contacted NB. They immediately sent another pack, and it arrived in record time. I was able to brew that weekend still! Great support. The replacement pack inflated in 2 hours and the yeast performed great.

Response from Northern Brewer
Whenever shipping liquid yeast it is important to ensure the yeast can survive shipping. Consider contacting customer service for advice on ensuring healthy yeast or if your yeast did not survive.

Excellent results w/variety of styles
I have had very successful fermentations with this yeast in the Malt forward ales I have brewed. Browns, Porters,Winter Wormers, Old Ales, and of course Scottish ales. I especially appreciate the higher alcohol tolerance (up to 12%).

Great yeast!
I have made a winter warmer - 9%, scottish 80 - 6.2%, Imperial IPA - 11% and Maple Stout 5.9% with this yeast. Ferments well down to 50 degrees. Needs plenty of time to clear though. Yields great beer, is very versitile and easy to harvest for your next batch!

String Yeast!!
I recently used this yeast with Northern Brewers' Winter Warmer extract kit and was very pleased with the results. I prepared a yeast started 48 hours prior to pitching and the yeast went nuts in the fermenter within hours. I plan to save the yeast for reuse on a future batch.

Great Yeast
I've used this yeast a few times now and am always pleased with it. It goes well with everything from traditional Scottish Ales to porters and stouts. Very dependable and suitable for high alcohol ales. Its a must have "house strain" for the fall and winter months. Also Wyeast knows what their doing. Never had a problem with their products. Cheers.

Dependable Yeast That Ferments a Strong Ale With Style
I've used this yeast in the winter warmer kit a few times now with excellent results every time. I always utilize a yeast starter to make sure the yeast I'm using is alive and to encourage healthy activity once in my wort- this yeast is no exception. Within 12 hours I can see a good amount of activity on top of the wort and fermentation continues for about 5 days.

No problem with this yeast or any other Wyeast product
Sorry it didn't work out Madcow. Always make a starter to avoid any issues. Been using Wyeast smack pack products for more than 10 years. Extremely dependable and consistent results. And stay away from the dry yeast. Too much chance of it becoming contaminated and not working.

I accidentally popped the packet in this yeast about two weeks ago. It is now inflated. I plan on brewing the beer soon and I have kept it in the fridge ever since. Is this yeast still good to use to make the beer? Or should I buy another? thanks!

BEST ANSWER: I don't think a week or two would make a big difference but the yeast will be stressed and viability will be reduced a bit....probably depends more on the manufacture date on the package than it does on when you smacked it. I'd be more concerned with mfg date and the gravity of your wort. If below 1.046 or so I'd say you'll probably be ok; above that and you'll need a starter. I always use a starter with 1728 because 1728 makes tons of esters when it's stressed so, if you pitch that into a higher gravity wort prepare for some big stressed yeast character.
