Good on you Bigfish, I thought about ordering some cultures from them but doubtfull of its arriaval here. One of my friend ordered jamaican blue coffee beans, roasted, along with a 250g of another ground coffee, he only received ground one not the whole beans.
Yeah, it is way too sterile though.
I tried a wild sourdough and didn't get anything going when I first tried. I had to bump it up with kefir and commercial yeast.
