Yeast Guide

[Don]

Got my book "Yeast" by Chris White and Jamil Zainasheff the other day.

"We brewers don't make beer, we just get all the ingredients together and the beer makes itself"

It covers:
The basics of good fermentation
Yeast Biology
Fermentation timelines
High gravity beers
Bottle conditioning
Cast conditioning
Pitch Rates
Dry yeast
Yeast storage
and a lot more

You need to get a copy it looks well worth the investment.

My birthday is towards the end of the month, and I've got it on my wish list.

I never get tired of reading about yeast. Is that weird?

[Don]

Not for a brewer.

[Don]

I didn't know that..
p107.
Yeast strain and condition also impacts the hop character of a beer. ..... Differences in cell surface, cell size, pitching rate (I did know this one), growth rates, and flocculation characteristics all play a role in dertermining the amount of isomerized hop acids that make it through to the finisher beer.

So,what's the break-down on all that?

I haven't finished it all yet but different yeast strains give you different IBU's from the same amount of hops.
I don't think for the home brewer we will notice this. But the big brewers might.

I've been reading through the yeast book about oxygenation. I'm looking to upgrade my oxygenation method to include using tanked oxygen. I believe I'll get a regulator with a flow meter, and utilize the larger tanks for consistency and lower oxygen price. Is anyone using this type of set up?

I know there are members using the small red ranks. How long does the small red tanks last from the hardware store?

[sirgiovanni]

I buy a new tank about every 6 months.

[Don]

I bought my tank this week and plan to start experimenting on my next brews.
I have a regulator and a flow gauge that will read up to 1.5 lt/min.
I think 1 liter / min is want I need to shoot for.

If I don't get many batches out of the $7 bottle of O2, I have some extra B-tanks I can get filled for the price of the little red tank.

Will keep you posted.

Yes!!!

You got to stay up on them or they might take over.......
They are everywhere
