What are the hottest non extract sauces out there? I got alot of suggestions on another thread to check out Stillmanz/Scorpion but the only problem I can see would be the high shipping costs. Are there any other hot sauces available in the US? Also, why are the Aussies making the hottest sauces...Do the chiles grow hotter in the soil or do they water them with Fosters BTW...I know Fosters is a joke beer in Aussie land.
