Aright so I have a 0.75 L starter going with wyeast 3787 trappist HG. I'll outline my process just to be thorough, so bear with me.
-I submerged my gallon jug into a bucket of starsan for 5 min
-I opened the lid on my cooled starter wort and poured it into the jug
-covered with foil and aerated by shaking
-pour in yeast and cover again
I came back an hour later to find a singular fruit fly floating in my starter
So I fished it out with a sterilized knife immediately (pain in the ass). I checked back an hour later and its going strong with no noticeably off aroma.
My question is, should I pitch it? Since it was only one fly, would the yeast not beat out any bacteria that may have contaminated the starter?
