Coopers yeast - attenuation

[wheazy_joe]

Anyone know the attenuation % of Coopers standard ale yeast?

Can find info online about most branded yeasts but not Coopers.

For info I am brewing their Canadian Blonde.

My recent Canadian Blonde was brewed to 22l with 1kg Coopers BE1, started at 1042 and finished at 1012.
I find that the Coopers kits usually attenuate pretty much in line with the calculator
http://www.brewersfriend.com/homebrew/recipe/calculator/
with a small margin either way.
I added a dry hop of 35g Cascade which worked well, but found that I had undercarbed at 4.5g/litre priming (table) sugar, so you might want to think about that when you come to bottle/keg.

Cheers Terry, have done the kit before but to a slightly different recipe than this time. Was just wondering about attenuation % so I have an idea of a final SG target.

Interestingly I took mine to about 22litres also, but added 1kg of BE2 plus 150g of brewing sugar and 100g of honey and came out at 1044 starting gravity. I would have expected this to be a bit higher than your 1042 with just the BE. Perhaps I didn't mix the ingredients enough?

Anyway, I'm yet to get a coopers kit below 1010, so if i can get something like 1012-1010 that will be perfect.

Will be carbing with 2 carb drops per 500ml bottle or 1 per 330ml bottle.

Just looked my records a bit more, if it's any help.
All my Coopers kits (AuPA, Canadian, IPA, and English Bitter) have finished in the range 1009-1012, with SGs in the range 1041 to 1045 governed by extras added and start volume.

it a long time since I used coopers yeast but I remember its about 75% AA. terrym's data backs this up.

I use this calc. It's give you attenuation figures as well as abv%

Cheers MyQul, 75% would bring me to 1011, bang in the middle of my suggested 1012-1010.

Am working through my last couple of kits then gonna do my first extract which I got delivered from the home brew company last week. Not saying I will never do these types of kits again, but hoping the extract is a step up in beer quality and convinces me not to go back the way!

Checked my notes from when I did that kit it was 1049 came down to 1012 I used 1KG DME and 250 dextrose that time.

To be honest mate I said the same as you, I thought after I did my first extract I would do an extract every other kit.. As it was I never even did another extract

Did the extract convince you to jump to AG?

I've never been an extract brewer but as I undertand it extract is definatley a step up from kit. However if you've got time go AG. AG is much cheaper than extract. With AG you can make the freshest wort (freshness = better tasting/quality beer). As some grains need mashing these are unavailable to extract brewers. The downside of course is time. It can take 4-5 hours to make an AG brew, although you can spread the brewday over 2-3 days like I do to do a brewday in managable chunks

Kind of what it does if nothing else is introduce extra steps for you to get used too. Such as Steep boil add hops and cool downs ect

Because I did extract with steeping specialty grains I kind of gathered why not do a partial mash so I have like only half extract.. (extract isn't cheap) did a few partials and then just did an AG.. with a big pot you can still do smaller AG batches to get it down.

When I did extract with grains I was surprised how much "cleaner" it was than kit.. moving on even to partial mash you can get just fresher flavours.

From that point onwards I just couldn't see myself going back to kits, I do not wish to discriminate them, they make drinkable beer and great for new comers.

Sounds weird I find flavourts in kits blunt whereas in AG they are fresher and much more prenounced and you can just hit the notes.

On to this kit you dry hopping it again? didn't you do that last time (I think I was suggesting it to you when you signed up here)
