Chinese garlic is very obviously being grown indoors in hydroponics/aeroponics or some sort of greenhouse setup - There has never been a speck of dirt on it. The heads are of extremely consistent size. Listen I prefer local garlic because its many times more flavorful, but I keep garlic so long it sprouts as it is. So I buy it at the grocery store year-round.
Instead of Chinese garlic I just use the jar of preserved minced garlic at Costco when no local garlic is available. It's grown in California and basically pickled in citric acid. It adds a little sourness but it's better than buying questionable produce from China IMO.
I also have a shitload of onions hanging in the basement from my garden and they are so potent it makes up for any garlic weakness!
