Warning: This will be somewhat long & detailed, cliff notes at end!
So n00b here long time lurker, new poster/brewer. I brewed my first batches a couple weeks ago after tons of research. (Phat tyre clone & Apfelwein) Just racked the Phat tyre to secondary and got a taste it was pretty good! After my first experience brewing in a 20qt pot partial boil on the stove in our apartment SWMBO did not enjoy the smell of boiling wort. So I have been banished to outdoors, I just ordered a burner, 40quart pot & chiller to start full boils. Now I am pretty excited to be doing the full boil as the partial boil in our smallish kitchen and trying to do an ice bath sucked!
So I just ordered the Three Hearted Ale from northern brewer, per their directions it states to add 25% less hops which just seems too much of a rough estimate for me. I am a huge nerd and love to get into all of the specifics of everything and homebrewing is my next pet project. I downloaded the trial of Beersmith and have been toying with inputting the recipe to convert to full boil vs partial but I am wondering if someone can give me assistance with that.
Here is the NorthernBrewer ingredients schedule:

Now as I understand it the IBU's will be out of wack as the full boil provides better efficiency. Now I am not quite sure how to correct this, I tried putting the boil volume to 2.5gal and batch size to 5gal and it gives me an IBU of 32.5 so is that what the IBU of this batch should really be, and how do I correct for this? (does beersmith have some auto method for this?)
Okay, with that long winded question out of the way I come to my next concern. Boil volume... Since my new pot is aluminum I plan on boiling once before brewing in it to first build up the oxide layer but also so I can estimate my hourly boil off percentage. Now obviously this will not always be exactly the same so this is where my concern comes in. Using a set kit like the one I have just ordered, what happens if after 60mins I end up with more volume than I expected this will cause my OG to be off right? Can I just boil a little bit longer to correct (will this cause any problems?)... Or should I have extra DME/LME on hand to add and correct the OG (if this is the right answer how would I calculate this)? On the flip side, what if I am coming up shy of 5gal near the end of the boil, is it okay to add some water? I plan on taking some CPVC and creating a marker stick to gauge the volume in the pot to assist with gauging where I am at during the boil.
I also plan on trying to make a starter, what size should be good to pitch for this batch? I was planning on making a 1L starter using some DME and making it two days ahead of time on a stirplate, cool crash the night before brewing then decant the beer and pitch the slurry after it has warmed up to the same temp as the wort.
1. How do I calculate for the difference in hops using an extract kit tailored towards partial boils when doing a full boil.
2. When doing a full boil using an extract kit what do I do if my boiled wort volume ends up being more/less than 5gal.
3. What size starter is a good bet for the Three Hearted Ale?
Thanks in advance for any help!
