During the Covid lock down in South Africa there was quite a controversial ban on the sale of alcohol for a few weeks which led to many people jumping on the home brewing bandwagon.
During this time a few news reports surfaced of people falling seriously ill and even dying as a result of drinking homemade beer.
I think these articles are purposefully exaggerated, misreported, and in some cases the beer involved was spiked with something to make it more "potent" like methalated spirits or IPA.
Can I, with sheer carelessness and supermarket ingredients, make beer that's so poisonous that a sip can kill me, or that isn't putrid enough for me to consume enough to kill me? The only thing I can think of to do wrong is bad hygiene practice and not sanitize my equipment, but that would most likely just make either vinegar or something undrinkably rotten.
