I made a recipe that was supposed to have OG 1.062, FG 1.012 (ABV ~6.5%). I forgot to note the target volume in the recipe (just the pre-boil volume), and wound up with a wort with OG 1.077. I chose to not dilute it at the time, just to see what would happen, and primary fermentation is nearly complete with FG 1.020 (ABV ~7.5%). I got this from a single starter of WLP001 and about ten days of primary fermentation.
Ultimately I'm happy chalking this up as a lesson in note-taking, but I'd like the beer to be as similar as possible to what I've made before. Which options are the best, if any?
Dilute beer in secondary, to match OG; add enough water so that the OG would have been 1.062.
Dilute beer in secondary, to match FG; add enough water so that the FG will be 1.012. (due to the 40% reduction in gravity, this doesn't seem wise)
Dilute beer in secondary, to match ABV; add enough water so that the ABV will be ~6.5%.
Pitch another yeast starter.
