It has a slightly more cayenne pepper flavor bite than Franks and Texas Pete but less of a cayenne flavor bite than Louisiana. It is one of my staples and a bottle lasts me about a month or three depending on how many other bottles of sauce I have at the time. Garlic is one of the ingredients but I can not detect any pronounced garlic flavor.
Kroger also make a "hotter" version of their sauce that I'll write about another time.
On my scale of 1 to 10, I give Kroger an 8 in flavor and a 1 in heat. It adds a tiny amount of heat with basically no discomfort.
I could not find a Scoville rating for Kroger hot sauce, but based on Franks being 450 and Texas Pete being 750 I'm going to guess this is around 500.
