Not too hot but definitely not a mild chilli sauce. We only use chillies with a Scoville heat unit (SHU) of 70 000 - 90 000. Our chilli sauce is made from the purest ingredients with no artificial flavouring, colouring or preservatives added. We only use 100 % pure chillies, rock salt and vinegar, nothing else, that are aged together for up to 2 months where after we strain the mixture and bottle it. No stabilizers or emulsifiers are used so a little bit of settling is normal although this is not more than 1% per volume, so a quick shake before use is needed. Packed in 125 ml glass bottles with cork stopper and sealed for your piece of mind.
