US05 Question

Post by J_P » Fri Aug 03, 2007 9:24 am

Hi all

Last weekend I used US05 for the first time and have a question about the head it produces. Usually I use Safale S04 and by day six the head has died down and is to all intents and purposes ready to bottle. My fermenter still has am inch thick head on it still, is this normal?

I am fermenting 23 litres of 1043 wort, I started two packets of yeast off in 1 litre of boiled unhopped wort if this helps.

On the plus side the head looks very like the ones I saw on the Yorkshire squares at Theakstons recently.

yeah it does seem to hang around longer like a top cropper.

My regime with this strain is to let it go for 5 days 17/19c, swirl rouse and up temps to 22c ish for 2 days to help it clean up diacetyll. Then cool down over 4/5 days b4 bottling.Much of the yeast will flocc out with cooling.

hope this helps
dave.

Yeah i have i brew on at the moment with US-05 and its doing the exact same thing, kind of weird to see the head just keep on gradually expanding each day (not at all like safale 04 were you have the initial explosive head and then it falls down.

I just practice a bit of patience with this yeast and leave it in primary for a few weeks until it finally starts to fall down.

BTW its a great yeast, super clean and lets the hops shine through so great for pseudo lagers/golden ales :D

That's just what I wanted to hear chaps. I am currently drinking an all pale malt brew I did with Safale S04 and it's the best AG beer I have done so far however, it has a real yeasty twang.

Steve Flack reckons S04 overpowers pale ales and I'm coming round to his way of thinking, hence the brew made with US05. I have also been reading that Danstar Nottingham is a good clean yeast too so that's what I'll be using this weekend.

Any thoughts on other clean crisp yeasts?

JP i think you've just named the big two for dry yeasts, beyond that i reckon you'd have to go to liquid yeast (which are a bit of a PITA and need mollycuddlying).
Nottingham and US-05 seem to suit my tastes, but you might differ, i guess its one of those things that you have to 'suck it and see' :D

I suppose I can ask folks advice until I'm blue in the face but I'm not going to know what I prefer until I get on and brew something!

I would like to try liquid yeasts at some point, however I'd like to perfect the other parts of brewing before I introduce another unknown into the equation. I think I may follow Jim's advice on using them and split the pack and keep it in the fridge. In your opinion are they worth the extra effort / cost?

I think they are if there's is something 'special' you want. The range of dried yeasts is getting pretty good though - but it would be better if Fermentis actually released ALL the dried yeasts they already sell in 500g packs in 11g packs as well.

JP I've only brewed three batches of beer and a cider with liquid yeasts so im not really qualifed to speak on the matter. But they do seem a lot more hassle ie the big starter culture a few days before.

I noticed a big differnence between differnet batches of a lagers (steam beer yeast) that i did with a liquid yeast, the second batch which was put straight onto the yeast cake of the first batch was much more superior (i guess because of the huge cell number), even though on the first batch I had made up a decent size starter etc.

Talking about lagers im going to be putting in an order with Ross for one of his fridemate controllers and obviously im going to have a bash at a lager.
I was wondering what are the dry lager yeasts like compared to their liquid cousins.
Has anyone tried the brupaks lager yeast (was thinking of getting the 100g pack), also just out of interest how much does 500 g of yeast cost?? (not that im going to buy that much).

I think the Fermentis Lager yeasts are about £30-40 for 500g. Ross at craftbrewer recommends S-189 of the Fermentis lager yeasts. I've used W34-70 and that works well too.

I used S23 and found it too fruity, and not a nice Kolsch style fruitiness. Avoid.
