winemakers nightmare, H2S

I have only had this problem once but had already made a racking tube out of 3/8" copper tubing and just used it when vacuum racking took care of it emediately.

after lots of research i found out that bananas when cooked down to a ugly pile of yuc is about the best yeast nutrient going.
not just sliced, but cooked down to syrup..peels and all. bananas are very high in nitrogen, which the yeast loves.
i am sure others may dis agree...but i am doing a 6 gallon batch of mustang grape...i added no yeast nutrient, but added 1/2 cup of cooked bananas, its fermenting like crazy, on day 4.
just saying.
