Maybe there’s something I don’t understand (I don’t drink coffee at all), but coffee is antimicrobial and doesn’t need to be kept out of the food safety danger zone. I should think it would take an extremely long time to grow pathogens.
Relevant study: https://www.researchgate.net/publication/388799782_Survival_of_Listeria_monocytogenes_in_commercially_available_refrigerated_cold-brewed_coffee
idk man, the shit that comes out of the drip tray of my coffee machine sure smells like it has a lot of bacteria in it
I think the concern initially was that cold brew may be more prone to bacterial contamination than normal coffee, because it has lower acidity and the water used to make it is not boiled. But like the study you linked found, it seems to be safe at least when refrigerated.
I’m the caveman who thought this was craft beer or something. Y’all drinking coffee cold? Scared caveman noises.
Doing longer extractions (12hr+) with room temperature water makes very smooth coffee with much less bitterness and significantly higher caffeine content. It’s also less fussy - set it up in the evening and have great coffee in the morning.
My therapist told me not to view things so negatively. So instead of saying “I have listeria”, go “I have thousands of new small friends”
Wouldn’t it be closer to millions?
Even better!
Maybe most of them aren’t friends, just some… Millions of new flatmates, meaning a guarantee of thousands of new friends!
Definitely. The minimum infective dose is around 10-100 million CFUs.
okay so since this is the science memes community, did I choose the right foodborne illness or was there a better punchline than listeria?
Listeria survives well in a cold, wet environment so I would say it was spot on.
I ran a microbiology lab that specifically tested for food borne illness causing bacteria.
Here’s a very recent attempt to assess the safety of cold brew coffee coming out of UGA. https://newswire.caes.uga.edu/story/10365/cold-brew-coffee.html
These findings line up with earlier work such as this paper doing a general analysis of cold brew coffee and this Canadian government report on detected food borne pathogens in cold brew coffee..
The consensus I’m seeing is that cold brew coffee, especially when kept cold, is not a great environment for most food borne illness causing pathogens to thrive. Bacillus cereus and potentially botulism would have been more accurate choices.
I am confused. You are not the OP?
* OHH THE OG OOP.
<bows>
Well I have had it 3 times (Caramel apples, Hummus, Ice Cream)
And I think I made that face each time sooo… Yeah I think it works.
Unless coffee is too acidic this is one instance where mentioning botulism might actually be justified
I thought botulism thrived in room-temp anaerobic environments? If theyre constantly opening and refreshing thier cold brew coffee and keeping it in the fridge then i dont think botulism is much of a risk.
Thank god , I was worried there was something I’d missed on cold brew coffee and I should be bleaching more things between runs
The thing I remember listeria getting into for my food manager safety cert was underheated nacho cheese and deli meats!
The key is to distill the water out and pour it into the new beans. You don’t even need new water, it’s pure 🔥 👌 💯 🤧 😍 😩 🔥
I wash my cauldron between batches. Seems legit.
