Late extract and Promash software

psuweatherman

I'm brewing a Hefe today and have entered all the info in Promash, but have a question about late extract method.  Is there a way to express this in Promash?  I'm also doing a full boil and I just don't want to much hoppiness with better hop isomerization.
I was planning on adding 25% extract at start and 75% with 10-15 minutes left

I believe someone here has a good way to solve this problem. Try searching the forum. I think it was Bugeater.
The rumor is that the new ProMash will be out sometime this year soon and that it addresses this issue."I always just sit on it with my pants down."

Here's what I do:  
I just momentarily reduce my extract amount in the Promash window to zero (or to however much I expect to be adding at the beginning of the boil).  I then take note of the expected IBUs calculated, and adjust my hops to make that number where I want it.  Then I put the rest of my extract back into the program.  Not super elegant but it gets the job done.

PS - Make sure your "Wort size" number in the program matches the amount you plan on boiling.  That figure also affects IBU calculations.

Unless I'm missing something, the only time the IBUs change is when you change wort size or time/amount/type of hop and doesn't take into account the amount of extract added.  
ps I did try what Pseudolus suggest.

Maybe you have your copy of ProMash set up differently?  
For me, increasing the gravity of my wort (by upping the amount of extract or grain or by increasing the expected efficiency) does decrease the amount of IBUs the software predicts I will get out of my hops.

Well, just finished brewing  and hit the OG spot on.  The wort tasted pretty good.
Used the B3 aquarium pump for 30 minutes and pitched 2L starter and it should take off like a banshee.
BTW the SRM was way off even with the late extract.  Hopefully that mellows as it ferments.

Apologies if this is stuff you already know, but
a)  Wort/beer in the carboy always looks much darker than it will in the glass, because light has to travel through a much longer width of wort/beer.
b)  It'll look a lot less cloudy after fermentation and a little age, too, which will change it's appearance substantially.
Of course, with an extract batch, your minimum SRM is determined by how your extract manufacturer made your extract.  Late addition keeps you from making it any darker but can't make it any lighter than you started with.Thanks for the tips, the rule of thumb I've used is look at the wort/beer in the siphon tube and that is a pretty good 1st guess.
