Umm, I was just sending a resume of this conversation to a friend and something occurred to me. If I have a 4G pot which is fairly full at the end of the boil, will I still have enough room to add the DME/LME in order to dissolve it or will i need to move a small volume to another pot, just for this step, then mix both into my fermenter?
 
Put the bag in the water,me in the water,shark's in the wat...oops,my bad.

You're gonna need a bigger pot!

Sorry couldn't resist Jaws is my all time favorite movie!

Now back to topic. Unionrdr and I brew similar, I mash 5-7 lbs if grains in a 5 gallon BK BIAB style. Then at flame out add a few lbs of DME or so to get where I need with top off depending on what I'm brewing.
 
Question from my buddy.. if we have boiled say 15L, then we ought to be able to just top up with an additional 4L and the OG should be correct due to the LME or DME substitution?

Yes and no. The extract will lend a specific number of gravity points, but the gravity of the grain wort will be dependent on the "mash efficiency". You'll learn what type of efficiency you'll get from your setup as you do more AG/PM batches. Most recipes are designed for ~60-70% mash eff., unless stated otherwise. I found that I got ~75-80% mash eff. doing BIAB with a fine crush of the grains (~.40 on the mill) and a setup very similar to yours (5gal kettle, paint strainer bag). In turn, extract yields ~100% eff. Your software will help you a TON with calculating the combination if doing PM and the mash eff. if doing AG, so you have an idea of what to expect in future batches. YMMV, and that's why it's a yes and no answer.

There's really no limit on what it can do, it's awesome stuff. All the ingredient and recipe add ons when you license it are awesome, and if you know the numbers for a grain/extract/hop/adjunct/yeast or whatever, you can add it yourself. I recently added Hop Shot CO2 extract to mine, along with a few yeasts I've been using that aren't in the database. Oh, and the Cloud feature is really handy for sharing recipes and equipment profiles. Cool $hit for sure.

Off topic a bit but I'm intrigued by your description of BeerSmith2. I recently got BeerAlchemy and am a bit disappointed. Is BS2 for Mac? Does it estimate mash pH based on water profile/salt additions and grain bill? BA does not, and there's NO manual, on line or otherwise. BS2 have at least a PDF instruction sheet? Does it sync between a phone and Mac?
Is it a portable shower or a monkey cage???
(Jaws again...)
 
Some think it does. I haven't anything to check it with yet myself. but I maintain good mash water to grain volumes just in case. the water around here has been really good. So not too much of a problem.

I believe if you add the water and/or salts you're using, it will make the adjustments. As to the accuracy, I can't say, I haven't played a ton with that part of the program. It will let you export recipe files, print a brew day sheet, share files, etc. As of now, there is not an app for BS2, but I hear they're making one. And it's definitely a monkey cage. :D
 
You're welcome. They call it BS lite,so I imagine it isn't as fully functioned as the comp version. but it's being compatible with the comp version would be a bonus.
