Not too hot but definitely not a mild sweet chilli sauce. We only use chillies with a Scoville heat unit (SHU) of 70 000 - 90 000. Ingredients are 100 % pure chilli flakes, rock salt, vinegar, garlic, ginger and sugar, nothing else. No stabilizers or emulsifiers are used so a little bit of settling is normal although this is not more than 1% per volume, a quick shake before use is needed. Packed in 250 ml glass bottles with cork stopper and sealed for your piece of mind.
