Low final volume

[Vegetarisk]

Just did my first full boil 5 gallon batch and realized I didn't adjust appropriately for boil off. I currently have 4.5 gal of wort in my primary and it's too late to add any sterile/bottled water. My target SG is spot on, is this something to worry about it? I checked the volume about 20 min after aerating and the foam had gone down quite a bit so I'm fairly certain 4.5 gal is the actual volume.

Nothing to worry about, I would rather have the gravity correct. Calibrate a stick so you can check volumes in the kettle for last minute adjustments.

Nothing to worry about there. I think this happens to all of us at one point or another

It would only be to late to bring the volume up after the beer has fermented.

True, although by the time I realized it I had no pre-boiled water readily available and it was very late. Hit my target OG of 1.075 with 4.5 gal, so i suppose adding additional water would have lowered this. Another lesson learned I suppose.
