What should I do to use the starter in my first AG batch this afternoon..?....Thanks
If you are brewing this afternoon, give the starter a good swirl and pour the whole thing into the cooled & aerated wort. The yeast is in suspension and you want to get all of it into your wort.
Other times, as mentioned above, you don't want the potential off flavors of the starter to impact your beer so you allow the starter to completely ferment out (I usually give mine three days or so), chill it for a couple of days so the yeast flocculate and settle to the bottom, and decant the starter wort on brew day, leaving just enough liquid to allow the yeast to pour out of the starter vessel.
