Interestingly, if you look at the menu for Juneteenth, it doesn’t include fried chicken. The only chicken is a dry rub chicken that wouldn’t be fried. So your evidence confirms they believe fried chicken is in fact not appropriate for Junteenth. That’s a good reference point if we all accept that the national museum of African American history is an authority on such matters.
Or, the lazier method would be they just don’t throw away their first pours which are full of methanol and so 3 or 4 bottles from each batch are poison. This can easily happen with someone who just doesn’t know what they are doing trying to not waste product.
The simplicity of that explanation makes it feel more likely to me.
