Hi yooper! Can't believe you saw one of my threads. Read many of your replies so it's a bit of an honour.
Okay sanitization went like this - i filled the 6.5g carboy up with water and added about 1.5 oz starsan. This one I just siphoned out into bucket/sink.
bottles were rinsed out well with water and then dunked into star san solution for about a minute each. I will admit, if bubbles existed, then I'd have jetted them out with water to get the bubbles out. Just doesn't feel right to drink something with sanitizer in it. Its possible that i sprayed out the primary fermenter with water if bubbles existed...
In the back of my mind, I am thinking that is the problem. Somehow you've either got too much star-san and can taste the result, or you rinsed off the sanitizer and got an infection going. That's where I'm leaning.
The recipe is solid, and even if you steeped at too high a temperature or something, you shouldn't have a foul taste.
As the others said, star-san is a very good no-rinse sanitizer when used in the proper amounts. It's an acid, so it's important to be careful when mixing. You want the right amount, so that it will sanitize properly. It has a nice measuring cup on it already, so you can just squirt from the top into the proper amount of water. And, it's no rinse so you don't want to rinse it off!
One last thing, star-san is a great sanitizer (I use it). But it's not a cleaner. So, you want to wash your dirty items in something like oxyclean until they are totally clean and rinse very well. Then, you can sanitize. It's best to fill your bottles and use the equipment while it's still wet with star-san. It's a wet contact sanitizer, so as long as it's still wet, it's still sanitized.
I hope I'm wrong, though! Because if it is an infection, the beer won't improve but instead will get worse.
One last thing I must have missed in the earlier posts- what kind of water did you use? That's the last thing I can think of that might cause off-flavors.
