Although we have already covered setting up your equipment profile in this post of the BeerSmith2 Guide for BIABrewers, I have written a more detailed explanation of how to set up equipment in this post on the BeerSmith forum.

I'm not sure if you can download files from BeerSmith as a guest so I'll attach them here. sigurdur has written a clever online tool that mirrors the spreadsheet below. Great job sig!

The next instalment of the guide, 'Converting 'External' Recipes to Your BeerSmith2 BIAB Equipment - Part 2' shouldn't be too far away.

Cheers,
Pat

I have just added another 3 posts to the BeerSmith2 Guide for BIABrewers.

If you would like more posts added to the guide, please let us know here. The guide though, actually has two purposes...

1. Helping BeerSmith2 Users: The guide aimed to cover the most difficult areas of using BeerSmith2 as well as recipe conversion in general. This is not insignificant. Anyone that studies and absorbs the dozen posts there will be well on the way to understanding and then becoming one of the few brewers proficient in this area.

2. Helping BIABrewers with the Upcoming BIAB Calculator 2.0: The BeerSmith2 Guide is also acting as a prototype for a 'How to Use the BIAB Calculator'. This guide will be easier to write now (and easier to understand for the reader) but a lot of it will simply be a modified copy of the BeerSmith2 guide.

So, if you have any suggestions as to what you'd like to see added, changed, re-ordered or better presented in the BeerSmith2 guide, this will also really help with the writing of the BIAB Calculator 2.0 guide. So, any feedback or requests you post here will be greatly appreciated.

Cheers,
Pat

Hi Folks,

I have a question regarding BeerSmith 2 Water Volumes!

I have only done a few brews, but I know I need to start with around 30L in my 40L URN.
After boil and losses I will have enough for my 19L keg.

Using the information online from Pat I have tweaked my equipment profile based on previous brew data.

I have entered data in my equipment profile relating to boil off data from a previous brew day as follows:
Calculate Boil Vol: Unticked

Boil Volume: 28.2L
Boil Time: 90 Min
Total Boil Off: 5.20L

This is the actual boil off within the 90 mins. So I have left "Use boil off as an hourly rate" unticked.

Evaporation Rate: 12.3%


When I use this profile with a Recipe the suggested starting water volume is around 30L which seems OK given current boil off rate for cold garage!

However as soon as I tick the "Calculate Boil Vol automatically" in either the recipe or the equipment profile the required water volume jumps up around 2.5L.

Do I need to have this automatic boil vol enabled?
Will it cause my issues that I am unaware of?

Sorry if this is a stupid question!

Thanks! :drink:

If you divide your total boil-off by 90/60 you should get your hourly boil-off rate. Try using that instead, and then ticking calculate pre-boil volume.

Your calculated pre-boil volume should basically be the end-of-boil (hot) volume - the total boiloff, which is the hourly boil-off times the number of hours (1.5)

Hi Stux,

I've given that a try but I still end up with a higher than expected water volume required value.
Think I need to gather more data, must have some dodgy figures!

On another note is it worth modifying the BIAB grain absorption setting if I squeeze the bag?

Thanks again!

Hi there dicko - another Blue Mountains man! (One of my old haunts.)

Calc Boil Vol automatically should always be ticked. I cannot think of a situation where it shouldn't be but apparently some people use it occassionally, mainly extract brewers from memory..

It seems like you already know that you need 30 litres in your urn, so yes, change your evaporation rate to suit. The default evaporation figure used in the 'guestimator' seems to be too high for small diameter pots and too low for really large diamter pots. It was the best we could do given the small sample size the figures are based on. So, change it before your next brew so your numbers add up to 30L and then start your 5 brews from there after which you can fine-tune all your numbers.

See you in the Blue Mountains one day ;).

Here's a quick update on some errors we have spotted...

1. Total water required refers to the volume required at boiling point not ambient temperature. (This is not a great issue).

2. Tinseth formulas are based on the pre-boil gravity whereas they should be based on the average gravity of the boil over the time of the addition.

3. Aroma hops are not scaling correctly.

Brad has been advised of 2 and 3 above as we regard these as big issues although we have recently discovered that pretty much all the software out there, if not all, is using the Glen Tinseth formula incorrectly.

I have asked the admin guys to remove, "Buy Now - BeerSmith2!" from the header of the forum. This might take a day or so. We have one key left. If you would like that, please PM me directly. When sufficient updates have been made to BeerSmith2, we will re-visit the idea of making it available on site again.

In the meantime, those of you who have purchased BeerSmith2 from BIABrewer, please feel free to let us know how you are getting along and thank you for going out of your way to support BIABrewer.

It is very much appreciated,
Pat

It's sad to think a great program, like beersmith, doesn't do it!

I have been using BS2 since getting it from this forum and I don't like it. Too many bells and whistles and the basics are hard to find.

I don't like having to open several tabs, just to get an idea of how efficient my brew was/is.

I now use it very basically, I input my recipe to get a rough idea on what OG I should get and that's it. I know my system, the boil off rate, the grain/liqour absorption rate and I know how much beer I'll have at the end of fermentation.
It doesn't matter how much I try to manipulate BS2, it just doesn't agree with my actuals.

All in all, I am very disappointed with it. Bring on the BIAB calculator!

I'm quite happy with it, I've done three brews with it so far and have hit my numbers pretty much dead on. Once I had my equipment setup had had a good play around with it to familiarize my self with the program I was happy. And as with any program or manual calculation, particularly with your bitternes calculations, you have to brew it, taste it, tweak it to your liking and brew it again. I have been brewing with home grown hops a bit over the last 4 or 5 brews so the bitternes calculations done mean a great deal to me anyway.
So the moral of my rant is use the program as a starting point and adjust recipe/boil off/ efficiency/etc as needed. Just like anything, once you get used to it, it is easy.
Practice Practice Practice!
Just my 2 cents anyway.
Cheers
Ps. I reserve the right to change my mind if thing go wrong in the future! :whistle: :lol:

Took me a while to get used to the software as its probably a bit too heavy for what I need!
I still maintain my spreadsheet however as I like to see everything on one page.

My spreadsheet helps me to know WHEN I started fermentation for example as I cube my wort.

I have been tweaking grain absorption ratio's and boil off as I am new to the AG game.

The sheet from my full workbook is attached, not sure if it will help anyone with the tweaking process.
Probably doesn't make much sense, so happy to answer any questions!

Cheers

Cheers Dicko, I've been mulling over my brewing record keeping and have been thinking of making a spread sheet to record the vitals from each brew. Thanks,, you've just saved me a lot of work :thumbs:

Cheers

No worries Yeasty.

I found it helpful to ascertain grain absorption and boil off averages!

I can send you my full spreadsheet if you like?

That would be great dicko, I'm a sucker for a good spread sheet. :headhit:
I found that as I like to brew something different everytime, I have a "Calculator" spreadsheet for every brew I do and I don't really get to grips with my figures so I end upworking from memory :scratch:

sorry to have gone off topic a bit. :blush: To bring it back in line with BS2 I can say that I'm slowly getting to know my way around it and have input a couple of old recipes. I used it in tandem with the calculator. I got more out of it during my last brew as I designed an ESB using what I had in stock.
