Ok, question for the AG guru's.

My last batch called for a 90 minute boil which I had not done yet. My first two AG's were 60 minute boils done on very cold, but humid days.

I boiled off a little over a gallon on each of the 60 minute boils, so I decided to collect about 7.5 gallons of runnings for this batch. It must have been less humid that day, and I noticed during the boil that I was losing quite a bit more volume, so I added about a gallon at the 60 minute mark of the boil.

I ended up with just the right amount to transfer after cooling (5.5 gals).

Anyone see anything wrong in doing this? I understand that it may not be the best practice, and I should have collected more runnings, but I figured that if you "top up" doing partial boil extract batches, then it shouldn't hurt anything.

Just curious.... Can't wait to try this one out (its a Ruination clone from BYO).

PS.. forgot to mention that my OG was spot on, so it didn't hurt efficiancy or anything like that....

No, no problems. Your just replacing some water that boiled away with more water.

Sure, you can do that. Sometimes I even do it on purpose -- my kettle will only take 6 gallons safely, and if I want a 2 hour boil for flavor but I don't have enough room in my boil pot I'll boil it down then add a little more water.

ok, thanks... I figured it'd be no problem, but I don't remember seeing anything in this forum about it (which is surprising, cuz pretty much anything is here!).

I was just curious if it affects hop utilization, important in reproducing Ruination for sure.

My pre-fermentation sample tasted incredible (the best yet) and og was right on.

Thanks again!

I agree that it should affect hop utilization (better utilization) depending on the time of the add and the gravity of your wort.
