We have attempted this particular oatmeal stout twice…both times we missed our target gravity by quite a bit. I’m wondering why?
We are still pretty new to homebrewing, so still trying to get all the proportions right. However we modeled this particular recipe after a kit we purchased.
I’m curious what causes a beer to miss the gravity target? In this case, our target was 1.050 - 1.058
Our actual gravity turned out to be 1.038…which means our ABV will be less than 3%
these are two of the usual (clift notes version) answers:
if AG, then perhaps the crush was poor
if extract, then perhaps it is over diluted or not mixed well.
others will probably chime in with longer, more detailed answers, but I’d look to these first.
+1 on more info needed. i think you might have tried a partial mash? EDIT, i see you posted your recipe and it looks like you dont have enough fermentables.
Ingredients:
.75 lb Black Malt

I’m still going with “wort/top off water not mixed well before taking the hydrometer reading” as to why your OG is off.
Your original recipe had 6lb of LME. This recipe has 3.3LME and 2DME. Which is very similar for sugar content. The specialty grains are not going to add much to the mix.
At 4 gallons we were at 1.035. We topped off to 5 and were at 1.038. We them aireated it for 2 minutes by rocking the pail back and forth…this should have sufficiently mixed it. Still at 1.038 after that.

You can’t be at 1.035 with 4 gallons and add 1 more gallon and be at 1.038 I agree it was not mixed well enough. Sanitize a big spoon or a stir paddle and mix it with.
The first reading should have been higher than 1.035 much higher than 1.038.
Not mixed well enough at some point in the process. If you actually have 5 at 1.038 now, then the original 4 was not at 1.035, or you didn’t have 4 or you don’t have 5 or you didn’t add 1.
some where the measurements are off or the mixing is off.
but who really cares for this batch. you made beer and even if it is not at the expected ABV, it’ll still taste good. Be xtra vigilant on the next batch, at all phases, and you’ll hit your numbers.
