Last night I made my first yeast starter for a porter that I'm making today. I was pretty excited to get into starters but since I don't have an Erlenmeyer, it turned out to be a pain in the ass. I had to boil the starter wort in a saucepan, and then transfer it to a sanitized, narrow-opening one-gallon growler. For this I used a sanitized funnel. I cooled the wort by putting the sauce pan in an ice bath. I asked my buddy to wipe the outside of the pan so that no dirty water dripped in through the funnel when I poured the wort in. Turns out that didn't even matter because, as I was pouring, some wort dripped down the side of the pan. So I think it's contaminated... being the rookie that I am, I still went ahead and pitched the yeast... I covered it with a sanitized piece of aluminum foil and I stirred the starter every half hour or so for the first 6 hours to give the yeast enough oxygen. The yeast seems to be fermenting the wort, but I'm afraid it might still be contaminated.
Should I discard the starter, or use it for my brew today? I should also mention that the recipe called for a 1800 ml starter, but when I entered the recipe into BeerSmith, it said I needed a bigger starter...
Can anyone help me out?
