I have brewed about 6 BIAB batches normally just using the AG recipies. My numbers and gravity always seemed a bit off. With a longer mash it has helped to get closer then I found this site. So this is my fist BIABacus batch.
I am looking for a good Samuel Smith Oatmeal Stout Clone.
Ingredients:
•8 lbs. pale two-row English ale malt
•1 lb. crystal malt, 60° Lovibond
•18 oz. Flaked Oats/Or roasted oatmeal
•0.5 lb. chocolate malt
•0.5 lb. roasted barley
•1/2 tsp. Irish moss
•2 oz. Fuggles hops for boiling (4.2% alpha acid), for 45 min.
•1 pack Wyeast 1084, Irish ale yeast
This is for a "5 gallon" AG recipe.
The one thing the recipe provides is that the Oats should be about 10% of the grain bill.
I have a 15Gal Aluminum pot that I will be using. I believe it is 15in x 16in.
I would like to get 5.0 gallons into my keg after fermenting.
My question is how to I go about making this batch and seeing if the recipe has integrity? Using the chart I am obviously missing some information on the hop and grain bill as far as percentges.

naptowndon, Please post your BIABacus here, I have gotten permission for you to do so. We will take a look at, okay.
I'll be starting into a 3 day weekend here very shortly, may not be until (MY) next Tuesday.
In the meantime, post up a link where you found this recipe and why you believe it to be a clone. I friend gave me a bottle of this once, it was very good. I have used a pound and a half of "Simpsons Golden Naked Oats"; http://www.northernbrewer.com/shop/simp ... -oats.html in a APA. This was for a club APA showdown competition in 2011. It was best-of-show a great mouthfeel, but didn't fit the guidelines. I had a funny name for it too, something about "naked".

Thank you for your help. This is from the recipies at Homebrewtalk. I made one of these in an extract and it came out great and pretty close to the Samuel Smith. Yes Samuel Smith Oatmeal Stout is one of my favorite beers. Smooth, great mouth feel, and no after taste with plenty of flavor. Simpsons Naked Oats and the APA sound pretty good. I have had APA with corn but not oats.
My BIABacus surprises me as the TWN is more than I have used. My last bIAB I used 8.4 gal and missed my numbers low. I thought I was using too much water but this was just guess at that time and before finding this worksheet.

naptowndon, Are you still needing any help with this? If so, post a link to the recipe. I'll be glad to give my opinion. If this one is popular on that site, and many have brewed it, we will let the BIABacus scale the grain bill for us to fit your equipment and such. Let's take a look at the other pieces.
Also,Section Y should be corrected, that setting should be deleted for the oats, that is not correct.

Hey Mad Scientist I ended up brewing over the weekend. I didn't notice section Y until later and must have been left over when toying with the sheet.
I needed to spend more time with the sheet and my equipment. After getting the grains and changing the hops to EKG I realized I was measuring the outside of the pot and not the inside which changed my volumes and my numbers. Even with that my EOBG was estimated at 1.055 and my actual was 1.052 at 80.6F. My EIK was low however my EOBE and EIF were high. I am using a wort chiller, a ball valve and elbow that has about 1/8 inch clearance with whirlpool, and a hop sock.
Also, I did verify at LHBS in the clone book the recipe but not the percentages. Also it is recommended to use Crystal 55L which I can't get here.

When brewing and using the biabacus the TWN is less than the SWN but not by evaporation numbers. I started with the SWN (strike water needed). Why is TWN less and which do we start with?
Post #7 made 12 years ago
Hey. You start with both. The TWN is at ambient, about 60 F, whereas SWN is at a mash temperature volume.

So in the attached the TWN is 9.44 Gal and the SWN is 9.63 Gal. You start with the SWN and heating it you are supposed to end up with the TWN? I guess that is my confusion with that. I started with 9.63 but when temp was hit I had about 9.59. My Mash volume ended up 3/4 of a gallon low.
Post #9 made 12 years ago
Yes I understand that. My last brew started with TWN and never got to the SWN. This brew I started with SWN ended up with less at Mash Temp and both Mash Volumes were low. I use a metal yard stick in the middle of the kettle, actually recorded middle and both sides.
So I am gathering from your EOW post that I shouldn't care or worry about this? And I am also assuming then that I only need to worry about the TWN and not the mash volume or the SWN.

I have personally found that my mash volume to be very much spot-on, after I had very carefully calibrated my converted keg. Because I have a concave bottom, I measured that volume and entered that into Section X. I use a sight glass which I carefully mark the TWN, SWN, Mash Volume, etc. before I start the brew. I can't use a measuring stick in my case.naptowndon wrote:My last brew started with TWN and never got to the SWN.

Have you carefully measured your pots inside dimensions down to the mm? Those first three estimated volumes should be fall into place.

Also noticed, since you didn't hit your mash volume, naptowndon, that incorrect setting in Section Y, did you end up catching that before your brewday? The grain bill changes quite a bit when you remove that in Section Y. The grain bill goes from 13.07 pounds to 13.50 pounds. Maybe your volume and your OG was off because of that...naptowndon wrote:Hey Mad Scientist I ended up brewing over the weekend.

I did catch the flaked oats in section Y prior to boil. I have not measured down to the mm and which is why I need to spend more time with the equipment to dial that in. Flat bottom kettle so I was tracking the 3 values and recording the middle.
The beer always tastes good and was close. Just trying to figure out why I was off. As I was thinking I didn't account for the 80.6F temp that I took the gravity reading at either.
The SSOS fermented vigorously, a rolling fermentation, for 2 day then slowed and still bubbling today. Will move to secondary this weekend.
I will try to dial it in to the mm before my next brew and have the sheet checked first.
