Saflager W-34/70

Post by Colliedog » Fri Dec 01, 2017 9:38 am

My question is one I know the answer to, however: I am planning to brew tomorrow using Saflager W34/70 and was intending on fermenting at the higher end of its range. I had (wrongly assumed (I know what assuming does)) that one pack would be sufficient for a 21 litre batch however on checking the pack last night it states one pack is good for a 10-15 litre batch.

My questions is should one pack be ok if I am fermenting towards ‘ale’ temperatures or should I postpone? Unfortunately I can’t get easily get more yeast and have no more in stock.

I've always used 1 pack with excellent results. I say just go for it, it will be fine, especially at the top end of the range.

I recently brewed an Alt with 34/70 and fermented at around 60F, hoping to add a bit of esters to the brew. But the result was virtually as clean as this yeast produces at 50F. It seems to be a very tolerant lager yeast.

I used 2 when I did my 20L or so (fermenting at 12-13C), and it rattled through to FG in a week, not that I was in a rush. My friend had done the same recipe with only one sachet, also at 12-13C. both were very good indeed, and continued to improve in the bottles after normal lagering and conditioning.

i use that yeast a LOT , its a very tolerant yeast , like mabrungard said , I've fermented it at 16c to good effect. it will power through ferment at that temp , although i'd still leave it ferment at least 2 weeks.

I've just brewed a "historical" Australian lager from the 1950s using W-34/70, pitched at 13 degrees and allowed to rise to 18. Surprisingly it didn't chuck sulphur like it always seems to do at low temperatures. I used slightly less than one pack as I rehydrated in a small pyrex bowl and spilled some. Doh.

I'm a week away from bottling my first batch made with this, been using s-23 up until now. Looking forward to see the contrast.
