S-04 yeast attenuation

[HebridesRob]

Didn't know that! Thanks. Mine has no depth indication, so maybe it's a total immersion thermometer...?! I got it from a home brew shop.

Just got mine out to have a look. 76mm.
I'm normally pretty clumsy but I've managed to keep my thermometer for nearly 30 years. Must be some kind of record!

As far as taste is concerned, is it right that S-04 can be quite fruity?

Yes, and a little "bready" too. I'm not a massive fan, but I think it's ok. I'd like to try some more English strains.

I'm not an S04 fan either. Prefer Nottingham. Even the cheap Muntons yeast seems better to me. But there are far better liquid English yeasts, the two I've used are both miles better, WLP002 and Wyeast 1469. For English ales.

I got put off buying liquid yeast after I read their data sheets. How do you store them?

 

[clibit]

I just store them in the fridge. What put you off? You prefer to use dried?

Not enough experience with all the yeast available to make a preference.

I read the While Labs data sheet. It scared me...
www.whitelabs.com/beer/guidelines-white-labs-pitchable-yeast-cultures

* It is best to use the yeast while it is fresh, ideally within 1-3 days of receipt. We have had brewers store the yeast 2-3 weeks before use, and never have a problem. Always store the yeast at temperatures between 36-40°F (2-4°C)."

Fridge isn't that cold.

There are lots of people using liquid yeasts and not adhering to those storage conditions. I think they are protecting themselves, similar to food use by dates. Probably with direct pitching in mind. If you keep the yeast in the fridge and make a starter it's fine. Do you not keep yeast slurry in the fridge?

I've been doing a bit of reading. I think I've been using it roughly the right way, inserting the bottom section up to where the scale starts, which is around 7cm I think. And I checked the accuracy of it once, and got very accurate results. Which re-assured me.

I've used the Wyeast smack-packs which are easy and excellent in use.

Back on topic, I seem to recall that S-04 is the Whitbread strain. It does floc well. But if I had the choice, I'd probably go for some slightly cloudier US-05 as it has so little flavour.

Which Wyeast have you used? I prefer 05 to 04, but yeast flavour can be a good thing.

So far just the 1056 (Californian, ie. US-05) and the 1728 (Edinburgh). I originally moaned about the 1728 but I didn't give it long enough to swell before pitching as it was a few months old. Worked well once it kicked off. The 1056 started vigorous activity within only a couple of hours or so. That achieved 83% attennuation at 11% ABV.

Currently have the 1968 (Fullers) waiting for me to open it for that Porter shortly.

 

[clibit]

I've got a 1728 in the fridge. Currently fermenting with WLP006, a new one for me, and Wy1469, which I've used before, nice flavours. 002 has been good for me but you can get diacetyl, and I wouldn't ferment too warm. It's quick, it clears brilliantly, and tastes great, you just need to control the temp.

Never bothered. Just use a new packet every time.

 

[clibit]

With dry yeasts I usually pitch a new pack too, but the 002 and 1469 yeasts both produced beers I couldn't make with a dry yeast.

Apparently the Mangrove Jacks M44 is a dry version of Rogue's Pacman Yeast, Wyeast1764.

The British Ale Yeast M07 Is similar to Wyeast 1098 or WLP007, attenuates 10 percent more for higher gravity beers up to 1060

One of the guys at Brew Store in Edinburgh told me this too.

 

[clibit]

People online seem to be saying it's similar but not found anyone certain is it the Pacman strain.

I have used it and can confirm that its a true top fermenting yeast, it had a 3-4 inch Krausen on both the brews i have used it with. The Newcastle dark ale is meant to be good as well, but have heard mixed reports about the Burton one they have.

I wondered where all the popcorn comes from.
