Oats as an Adjunct

[Turricaine]

Did the following today:

3kg Pale
250g Crystal
500g Supermarket Whole Oats

Mashed at 62C for 90-120 minutes with enough water to submerge the grains.
Sparged with enough hot water to fill vessel.
Used 2 Oz of Fuggles in the boil.
Used Muntons Gold yeast sachet after heat transfer.

How will the oats affect the beer?

Normally, supermarket oats need to be pre-cooked, but with a two hour mash you will probably have better head retention, a smoother mouthfeel and more body.

They will make the beer quite cloudy as well, and they would have done that even if you had cooked them.

Yeah they will make your brew cloudy, for sure. I did a pale ale with half a pound of oats the other day, and gave it a 40 min protein rest to try and beat the haze but it still looks cloudy. Can't comment on how it will taste because this is the first time I've used them

 

[Turricaine]

Really, my current batch is hazy because of the cooked rice i added to the mash.

When I used oats before (250g "Ready Break" cereal) it worked out good.

If this batch works out cloudy im gonna be pissed.

I do think it's kind of funny you asked the question "how will the oats affect the beer" AFTER you've brewed instead of before...

 

[mysterio]

Well, I don't know if it will be cloudy once it's ready. Maybe not. I wouldn't have thought rice would have given protein haze.

 

[Chairman Cheyco]

I've never heard of rice giving protien haze either, it's supposed to be almost invisible as an adjunct in terms of flavor and colour/clarity.

Oats=clouds. Send it my way if you don't want it.

 

[Turricaine]

ok, its only been 8 days in the keg but already its clearing nicely. Just a tip for people that oats really do do the job nicely. I'll be working on my stouts though and will use powdered oats next time.

Could it be a starch haze from the rice?

What does the rice do for the beer?

What does the rice do for the beer?

adds fermentables and makes it lighter.. I used rice in my asahi clone it was slightly cloudy even after running through a 1 micron filter but tasted good

 

[Turricaine]

Ok I see it's slightly over a month since I did this. It's not a bad brew but it has turned out less than clear. The taste is alright though. But I just wanna conclude that oats will make the brew cloudy so it's better off left in the stouts.
