Obviously the BS prediction has been improved since the last time I used it!  Good to know.  And of course, the FFT is always a good idea.

Yeah, I've been consistently impressed by how good it is...that said, I have spent some time calibrating various values on my end (mash efficiency, boil-off, mash tun dead space, etc.) over a few batch, so that initial effort paid off.

So if you make the same recipe with say, 5% crystal vs. 30% of the same crystal, the FG predictions somehow can compensate for that?

Good question! I did a pair of mock recipes--one with 80% 2-row and 20% crystal 80, and another with 77% crystal 80 and 23% 2-row, both of which had a calculated original gravity of 1.050. BeerSmith indicated them each having a final gravity of 1.011. So, it looks like BeerSmith doesn't adjust for fermentability of crystal malt and the like.

I suspect this quirk hasn't been a major issue for me because I'm generally not brewing beers with a high percentage of unfermentables malts (I'm usually doing recipes with <15% crystal/roasted/unfermentable malt, and most of my recipes are under <10%).

Anyhow, fascinating--I learned something today!

AFAIK, it takes a standard attenuation for each strain and adjusts based on mash temperature. It does separately account for the fermentability of sugars though.

I would say it's a tool like all others.

Good tools help but they don't make the carpenter.

Is this all in Beersmith 2.0?

If so I may finally upgrade...
Corn is a fine adjunct in beer.

And don't buy stale beer.

Don't do it! I'll custom make you a spreadsheet before I allow you to be tainted by BS! (I kid, but I do love my Excel )

Again, excel is a great tool. I use it everyday. Depending on your desires and expertise you can set up awesome spreadsheets.

Beersmith is already set up. I'm happy to use it so I don't have to think about it. Still some thought but for real most part it's plug and play.

For the record I have not delved into the depths of Beersmith. I use it surface deep at best. But I've got some awesome financial models I can share in excel...

I've got some awesome beer software models I can share in excel...

I'm just goofing around. At the end of the day I stayed with spreadsheets because it allowed me a level of control and content just not available in off the shelf software.

It would be too much like work.

I like to get away from work as much as possible.

OK, that spreadsheet is a thing of beauty! Nicely done. There is certainly something to be said with tailoring the whole ball of wax to one's own personal brewing system and procedures!

That's pretty sweet! I made my own, and switched to Beersmith at some point. I like having it available on my phone. On the other hand, I don't love Beer Smith's interface. I feel like a lot of it is not intuitive, and while there are a ton of writeups and video's on how to use it, I don't feel like it's something you should need to have training on. I might need to take a second look at mine, maybe include a tasting notes section.

Ladies and gents,

I sat on the porter for three more days, ramping it up from 69 to 72 degrees and it dropped to a happy 1.020. I  bottled it after three days of steady twenty and it smells and tastes great.

I'm still waiting on the gallon of BE-256 beer, which was already primed. I'll finish that tonight and let you know how it went.

thanks again for this terrific, and educational, thread.
