Cooper Stout W/ Rye And Oats

did anybody catch i also dumped in 2.5 cup of dex?

How is efficiency calculated? I have a feeling my very physical process of sparging at mash temp may be wrong in some way

Yeah, I only noticed it when I went back to verify my own figures! If two and a half cups is about a pound of dex, then you're roughly in the ball park for OG, but I'd also check your mass and volume measurements, eg. don't rely on fermenter graduations unless you've verified them, that sort of thing. Of course, check your hydrometer or refractometer regularly in plain water as well, all of the fundamental measurements need to be checked regularly.

There's a few different ways to describe efficiency in a home brewing context as it can mean something different depending on where you're at in a particular brewing process. However, BeerSmith has a reasonably thorough explanation, but google is your friend if you want to read more. Using brewing software such as BeerSmith, ProMash, BrewMate, etc (I use StrangeBrew2) will allow you to nominate a particular efficiency to help you formulate recipes that suit your own equipment's performance to give you exactly what you wanted in the fermenter, and that's where the efficiency figure comes in handy. However, for now I'd not be getting too excited about it as you're getting decent yields (i.e. efficiency is behaving as expected) and it really won't have that much impact on fairly coarse recipes like the one you did first. So, you can just keep throwing recipes at your BIAB bag and you can be reasonably confident they will perform as expected.

I recommend novice brewers wanting to try BIAB avoid sparging- the original/ stock BIAB method doesn't have a sparge step and it is very simple, so is attractive to anyone wanting to learn all- grain brewing. Use Nick JD's All Grain for 30 Bucks guide, or alternatively the BIABrewer Mini-BIAB one, but also there's loads of BIAB threads in the Beginner Partials/ AG sub- forum, have a read through those for ideas and inspiration.
FWIW, the reason I sparge the Maxi-BIAB is that I'm trying to extract the maximum batch size out of a 19L stockpot, i.e. enough to fill a 19L cornie and a handful of PET bottles, stock BIAB in the same pot would only do about half that volume. Most novice BIABers aren't trying to achieve that, so there's probably no need to sparge, but it is a tool which may be handy later on.

HTH! :icon_cheers:

3.5 cup is about a pound of dex.

I wanted to keep to keep the OG down a little not knowing the the ability of the Coopers yeast to deal with the higher alcohol content. I did want to give it some easy to chew on sugar so it could multiply and ferment out the whole batch.

For a second day observation, the batch has slowed dramatically. I will rack it into a glass carboy and measure gravity again. If it doesn't seem to be moving much. I might switch yeasts. My aeration was pretty pathetic. I was scared off of aeration after reading up on Hot Side Aeration. My last batch with oats in it has absolutely no head to it. That, I'm wondering is a problem of Starsan foam in my bottling or my over-aeration while it was still warm.

The advantage to glass is you can see CO2 bubbles and clarification.

racked into a glass carboy. Oh my goodness, the gunk in the bottom!!! That was a lot.

Measured gravity today. 1.011 at 72F = 1.0123 at 59F

OG 1.061

gets me 5.39 abv

and 63.9% converted solids

so far, that is. It's only been 2 days

slowed down a lot. I might be bottling soon. I'll do a gravity later today

1.011 @ 68F = 1.0119 actual

from og 1.061

that gets me a 6.45%abv

Bottled yesterday. Black as night.

Tasted the stuff at the end. Kinda rough. I can't wait to see what a couple weeks does for it.

I'm having another one right now. Nice tan head and decent lacing after I swirled it up. I needed to pour it slow. I can't see through this beer to view the sediment till it comes out of the bottle. Smell chocolate caramel, raisin, lemon rind. Very floral oily hop character. Malty with a metallic flavor. Bitter chocolate. The spiciness shows up pretty late. Espresso, grass, not very sweet. Creamy in the mouth, medium carbonation.


Overall it's pretty darn good. I will make this again but will back off on the flavor hops.

This stuff is getting very good now. The creaminess from the oatmeal and carbonation is marvelous. Head and lacing have improved. It is mellowing from the peppery bite it had before. I hope I can save some for some local competitions. This is wonderful. Yes its a partial, the 2-row, rye, oatmeal and hopping are my doing with you fellas help and expertise.

I thank all of you for your help

Cheers!!

Awesome, well done and congratulations on being patient! Some of my most memorable beers have been partials. :icon_cheers:
