Oatmeal stout final gravity
« on: December 28, 2016, 06:47:05 AM »

Ok guys,
Just took a final gravity reading and im at 1012 beer smith says fg should be 1018. Thats not my issue. The flavor is leaving alot to be desired. The roast isn't very prominent,  and there is a sort of mineral flavor along with a tongue tickling kinda thing going on. Ive experienced that feeling in stouts before.
To make it somewhat enjoyable can i use nibs or vanilla to add some flavor? If so do i have to prep the nibs or vanilla beans for secondary?
All tips and tricks much appreciated.

Sounds like maybe too low ph in the final product.  Do you have any baking soda? Pull a half pint and gently stir a tiny amount of baking soda in. Like 1/8 teaspoon. See if that changes it for the better

Interesting sir, I'll give it a shot. What's the idea behind that?

Beers with roast, inherently acidic, tend to finish a little low ph. If the pH is too low it can make a beer taste and feel sharp and thin. Baking soda increases ph. If you add a touch and it doesn't improve, add a touch more. If you add too much it can become kind of salty. But this is a cheap easy way to see if your beer is fine but just too low ph. I suspect you will notice immediately that by raising the pH your beer is less tangy and sharp, more soft and rounded.

Once you know the problem there are ways to address the issue.

+1.  My only other guess is too high a ferm temp, but I assume you have that under control.

I pitched@ 60f ramped 1 degree everyday held at 66f until activity stopped, checked fg an sampled.
Its been cold lately and i dont have a heat belt for my fermenter. I used an incandescent light in the mini freezer for heat.

Hmmm, never been a big fan of any light as a heat source.

My LHBS didnt have a heat belt in stock so i used the method they use in their fermenters.

are you trying the beer flat or carbed?

Right out of the fermenter at 66f.
Twas a sample drawn for gravity reading.

carbonation can drastically change the perception of beer. If you have access to a carbonator cap, you could draw some into a small soda bottle and force carb to see if anything changes.

And to echo the sentiment on what others have stated, my darker beers improved quite a bit when I increased the PH.

I would love to force carbonate,  i just dont have any c02 equipment.

So for next time do i increase pH somehow before boil? I know certain salts are not reccomended during the sparge. I guess i could add things to the boil pot.

is this all grain or extract? If its all grain, use a water calculator like bru'n water. Not sure about extract. Everyones advice might vary, but if it were me, I would package it as I normally would and see what its like carbed.

Its all grain. I used bru n water for mash and sparge. I dont recall seeing anything aboot additions to the boil.
I could certainly give that a go.
