Ca John's Magma Hot Sauce 
(Heat rating 4/5)
Scoville Rating: ~500,000
From iconic US hot sauce maker.
A full 1 million Scoville unit floats atop the vinegar. It hides under the shrink sleeve until you turn it over. Remember the Lava Lamp? Well that's the effect when you turn it over. Shake it up and it changes colour, set it down and the capsaicin settles back to its hiding place. Made with 1 million SHU extract.
148ml bottle
