MBP's Ultimate Oat Hydration Guide
    #21980542 - 07/22/15 02:53 PM (8 years, 6 months ago)

I decided to save a few bucks and go with Oats instead of WBS.  Hopefully the grows will be the same or better as my WBS.  I came across several TEK's, like most people when they are looking into something new.  This thread is to put 3 of the most common procedures vs each other.  The whole point of this is to get water into your grain or what ever you decide to use.  I am following each TEK, only using water.  I will be weighing them as soon as they are dry enough to PC and pitting the final weights all vs each other in a battle to see which TEK puts the most water in your grain.  A few other parameters that are useful are things such as time and ease.

The setup :

First, I rinsed off the grain.  Not separate, but all together.


Zero'ed my bowl


I then weighed out 1000g, 250g for each experiment


I separated it my best into 4 equal piles.  Each one of them read 250g on my scale after zero'ing the plate.





30 min boil:

I started by boiling water, no grains with the water.


Once it reached a *MEDIUM HEAT BOIL* I added the oats and did not cover it with a lid

Here is how they look, freshly out of the boil and rinsed with cold water.


The weight



The Microwave:

I just got any bowl that could hold the amount of oats I needed and double their height in water.

I dumped in the oats and filled it 2x the height of the oats

Set the timer for 45m on high and walked away


Here is what they look like, freshly out of the microwave and rinsed with cold water


The weight


The Soak:

I put my oats in a thick pot with a heavy metal lid


I boiled enough water to cover them up x4 (I wanted it to stay hot longer) I was afraid of soaking them with such little water that It could go cold during the middle of the process and skew the results.




After the soak, this is what they look like fresh out and rinsed with cold water


The weight



The PC hydration/sterilize : (suggested by Inocuole)

I got out one of my jars and dumped the 250g of oats inside

I was having issues trying to figure out how much water to use.  I ended up eyeballing about 470ml of water.  I figured if it did not absorb, I can just dump it out anyways.

Standard process of PCing.  I boiled my water with the jar inside, put the lid on, waited till no more steam sputtering was taking place then put on my 15PSI weight.  It was then PC'ed for 1h 30m.



I will not be rinsing these off with cold water, because in the real world that would not be an option.  They were weighed after being stained of rogue water.

This is what it looked like when it came out of the PC.  The ones at the bottom were a bit gooey, I did not seem to notice it once I put it in the strainer and mixed them up. 


The weight




Things to say..

Microwave : I was overly impressed by the microwave.  It needed WAY more water than any other method though.  It seemed to cook off the water more rapidly than any of the above.  Either way, the grains still look great.  A few exploded but nothing serious and they are nicely hydrated!

The 30min boil : I think not having them in the pot while bringing the pot to boiling is key.  I will be testing that later on sometime though.  They turned out better than I expected.  No bursting and they are all nice and hydrated!

The 1h 30m soak :  Prob the easiest method if you don't want to pay attention to anything.  No bursting of any kind, all the grains are nicely hydrated and you don't have to be exactly perfect.  Which makes this all the more alluring for me and people trying to get into this hobby.  You can likely leave these for 5-6 hours with no bad side effects what so ever, as  Inocuole pointed out in his TEK.

The PC Hydration/sterilize : Wow!  Not only did it achieve the most hydration, It did something to the oats also.  They are REALLLLLLY soft with out exploding.  You can see the color is different.  It almost feels like they were cooked to perfection.  I have a feeling that as a community, we should be trying to dial in this method so it is perfect for all grains.  I might have a quest!

Extra Images :

On the left is boiled, on the right is microwaved


Side by side :
Closer



So, I pc'ed them all and knocked them up tonite 7/23/15



PE of course!  I will keep this thread updated with their progress.  I just wanted to ensure people that all these methods will work and you can't really loose!

I can tell you when I hydrate them, I bring it up to a huge rolling boil, and they seem to take up at least double the volume when hydrated. Sometimes I forget about them, and the water spills over the edges. It doesn't matter though, they take it in so nicely with ZERO clumping. It isn't shocking you can even pc to hydrate. Their outer hulls are INSANE. They can take literally anything from what I can tell.

I don't even use gypsum or rinse them. It's the outer hulls that make them so slippery, like sand.

I save my gypsum for bulk :wink:

You just outlined the soak method i used.

I did not use gypsum in this experiment, but I use it for ALL my grain soaks.  Why are you saving something that is $4.50 for a 40lbs bag?

Because it was a bitch to find around here lol. I cleaned the store dry when I found it. I don't mind the money. Just would like a place that would constantly have it.

Jealous lol. The bitches there didn't know what I was even talking about, and I hate drywall. I ended up getting these bags at the same feed/farm store where I got my oats. A ridiculous amount of them. Should last me a long ass time :P

All of this is good to know. I'll have to experiment with oats one of these days.

Oats are the bomb i put mine in my pc cuz its my biggest. Pot put water in till covers a few inches above them and bring to a low boil...start timer 45 mins strain till somewhat dry... load into jars then pc for 90mins..  i love oats... good experiment op..the pc method would be realy sweet if u find the correct ratio..

As soon as I have 7 free jar's, I plan to load up all 7 with different amounts of water and pass on the love to you guys.

The grains that were cooked in the PC were perfectly fine after I rinsed them off.  I just did not rinse to get the weight. 

It is going to be a long time since I am knocking up all these grains and I have none left.

Somebody can easily do this though!

I am just compiling ideas.  I hardly care about the view count.

Edit : Maybe I will do some other TEK vs TEK.. If I can actually measure some factor that might make a difference.  This seemed to be one of the only real "science" you can do with the randomness of this hobby.

I will have to do a WBS and RYE!  Just expand this to more than oats.

I'm all aboard.  We just tried organic oats for the first time last night and they seem to have turned out well. Boiled and colander dried.  A few burst kernels, but the kernels were not sticky and flowed well.  They looked like a cross between your boil and soak methods.  Thanks for posting your findings.  I'll see about getting some pictures up, but any useful info i'll pass along.   

What times are most people using for PCing quart jars?  I've been going between 65-75 minutes with no signs of endemic contaminants so far.

We.. As a community recommend 90 min.

Thank you for the reply.  I'm familiar with using grain spawn.  More particularly organic rye and millet spawn.  I have, in the past and it seems currently, less than a 5% contamination rate with my grain spawn with it being PC-ed for generally around 75 minutes. Do you think it would be worth the extra time and energy to up the time to the community recommended 90 min? 

Is that for any type of grain irrespective of source/initial contaminant load?  Getting the best possible quality is the aim with energy savings being a great bonus, as long as any measures they do not compromise quality.    Subscribing to this thread

Honestly I don't pc for anything less than 120 minutes. I found 90 wasn't even enough. I'm pretty anal about my spawn. As you can see:

Well there's a difference between colonized and cleanly colonized.

This is colonized:

Lots of members have noticed cobweb and trich from jars that look like this or better. Wet spots are bacteria. Not wet grains or wet spots. To colonize cleanly is the hardest. I had to change my pc times to 2 hours to reduce it.

This is (ALMOST) cleanly colonized, that's how hard it is to have it completely clean. This isn't even completely clean:


This is completely clean spawn:



Notice there's no thick cottage cheese looking mycelium or any wet spots.

Anyone who's done this for awhile will testify this is the hardest part of the hobby and is what will dictate the success or failure of bulk.



I've heard of people doing a minimum 3 hours on bags. I don't think that there really is overkill.
