What's happening here bd is that you are asking way too much from your kettle. Most BIABacus versions will warn you of this. I suggest that you put your recipe into BIABacus PR1.3K if it is not already.

Other members here may be able to direct you to posts about, "sweet liquor shops" and "juggling". Every time you stray from a full-volume brew, there is a penalty. Dilutions should be generally kept to a minimum and there is usually no reason why a sparge should ever be used.

I'm short on time now but hopefully you will be able to search on some of the above terms and/or other members here will explain things better.

BrewingDaze;

I have just noticed you have posted a follow up in the time it has taken for me to add my 2 cents, so if it is of no use to you now, just ignore the below.............



I have my own proper job recipe that has been sat waiting its turn to be done. I have not brewed this so cannot vouch for its authenticity one iota, so feel free to use or ignore what is in this spreadsheet.

However, what I have done is amended it to suit your equipment (35cm Dia, 26cm high pot), and held back 4 litres for a sparge (approx 25% dilution).
Due to the size of your pot/kettle I do not think you will get more out of it than this 15L VIF (which is still an achievement by the way)!

###warning#### use you could try sparging with a little more, boiling for less, using advanced trub reduction methods (hop sock is selected by the way). However, I would not recommend doing this, as the extra beer/wort you may get by doing so may be of less quality than if you didn't.

Have a look at the attached file, it may at least show you another way of going about this recipe.

Brewingdaze - It sounds like you are on the right track now, but I cannot (or should not) check your file because it is in .ODS format.
Make sure you keep the .XLS format as I don't know what could have happened to the cells/formulas during translation etc.

I think I may have followed that thread from JBK but maybe the recipe designer made some tweaks at a later stage? To be honest I can't remember so you may be better to stick with your own for the time being.

The only thing I would add (I know I shouldn't try and complicate matters); is that I have recently cultured the yeast from St. Austell proper job bottles, so if I were to do this recipe myself now, I would use their own yeast. Depends how comfortable you are with doing that I guess.

If you ever feel like looking into how it's done, I used the same principle as I documented in this thread Here.

BungBrew,

What went wrong? It was meant to be a 1.050 OG but only got 1.042 ?

If your beer taste's great in the end, than nothing went wrong. Remember that your brewing a beer to drink not brewing up numbers to read. The reason your numbers were off could be a combination of small things or just one. The pH could be to high or low? The grain itself may not be that viable or fresh.

Just because you bought the grain yesterday doesn't mean it's fresh. Measured amounts of grain may not be accurate from the grain supplier? I have seen some whopping errors in weight due to my own mistakes. I have a measuring cup that I scoop grain out of the bag. Each scoop is 1 pound in weight. Sometimes I think I may have miscounted the scoops. In re-weighing I am off by a pound or two! Stuff happens!

Your brewing! That means your smarter than non brewers. Your in the top 1% of the world! Enjoy the ride (and re-measure everything!)

For me. Every batch comes out a little bit different. I find the variation in outcomes keeps me interested and excited. (boring life?) Re-brewing a recipe that was superb last time may not be as good next time? I try, but the brewing Gods throw in the unknown and uncorrectable variables making life and beer ever more enjoyable.

[Bob has posted above while I have been writing here. All very relevant stuff.]

Bung has a few brews up his sleeve now and as far as I remember, apart from one bad brew day, things seemed on track so I think this problem is just going to be what mally alluded to - an anomaly. We all get them occasionally.

Let's do some exploring though...

Bung, you have done a beautiful job on recording your figures. This gives us a great chance of seeing if your measurements have integrity. When I say that, I don't mean you are crap at measuring, I am saying that single measurements can't be trusted for many reasons.

Where I go to in the BIABacus, initially, to determine measurement integrity is Section P. Let's have a look...

Bung.jpg

What we see is the following...

EIB and EAW should be the same but they are 7% different. Not uncommon as EIB measurements are hard to make well. Let's ignore the EIB measurement for now. The next thing I am checking is your KFL (not pictured). Your KFL was estimated at 2.53 and you got 2.48 L which is almost a perfect match. What this means to me is that I can give value to your EIF number as well (assuming you did take these measurements individually.)

Putting all this together, I think your measurements do indicate a problem on this brew.

Don't over-think it though because you cannot in hindsight. As Bob mentioned, the grain could well have been weighed incorrectly. Did you have the shop weigh it and then check it your kitchen/bathroom scales? If not, then we can explore no further.

Unless you have a method of double-checking your inputs, there is almost no value you can place on the outputs.

So, the only lesson for this brew is how you can double-check input weights and volumes on your next brew.

And, I bet you the beer tastes great regardless so don't worry on it ,

Lol! This one is a tricky one.

Firstly congratulations LG. Make sure you post your success in the BIAB Competition Success thread. Nice! And really pleased to see you take on the pure no-sparge method.

Okay what MS is saying here is that Section N should be blank because the 1 L was not a pre-pitching correction. You took the wort out before the boil where it's gravity would have been less than if you took it out at pitching. There's a few issues here...

Generally, you should not do pre=boil corrections based on gravity readings. Firstly you are relying on a single reading and they can be inaccurate, Secondly, you can't predict your evaporation rate as it will change from brew to brew. In other words, you make your plan and you don't alter anything on brew day until you get to pitching, That is why Section N is called 'Pre-pitching correction.' (It also looked like your pre-boil gravity was only 1.2 points off. This is nothing. In future don't give pre-boil numbers respect. You just got lucky this time .

And atm there is no go to place to get information on each section. I am writing it now though and I think it is only going to take a week .

One other thing is worrying me in your file. You adjusted the auto-efficiency by 15% but it doesn't seem to be doing anything. Your file is definitely compromised in that area. This can happen in Libre or Open Office if you accidentally unprotected the sheet. Bit annoying.

Anyway, put the recipe into PR 1.3K s 1.3 is obsolete anyway. If you do that and answer the following questions, I'll fix the file for you.

Q1 Was the 30.2 L before you took the 1 L of wort out?
Q2 Was the 1.041 GIK taken before or after you swapped the wort for water?

So do that and we'll get 'er done as MS says

Sorry you have to re-do the spreadsheet. Bloody annoying limitation of the BIABacus. Just make sure you always save it as an .xls file and I think it prevents this problem.


PP

Btw, you should rarely over-ride the BIABacus defaults. Notice how your evaporation over-ride only changed the total evaporation by 200 mls? Also the trub estimate differnece is also minute. Both these things will vary greatly from brew to brew .

Hey LG,

If you go to the BIABAcus Pre-Release thread, about the fifth thread down in the forum we are in, you'll see right a tthe very top of the first post two downloads which are both BIABacus PR 1.3K's.

Make sense?

brewingdaze expressed the same confusion in this post but in the main release there won't be this issue.

I'm worn out now so a going to sign off but your file was definite compromised as I could un-protect it without using a password so you need to download 1.3K and never save it as anythiung else but an .xls file.

Also don't drop your evaporation rate. We will have to talk more about getting your goals right .

Anyway post 1.3K and we'll get the Recipe report sorted'


PP

P.S. Just check your file above and it is definitely compromised. Just go the 1.3K.
