Well, I don't know but clearly people aren't getting sick all the time from drinking beer. So it's evidently safe enough. I wouldn't worry about it.

Discussing ways to reduce waste and build community!
Celebrate thrift as a virtue, talk about creative ways to make do, or show off how you reused something!

Seeing as people drinking regularly get sick, maybe its the bottles not the alcohol.
The amount of people informing me the last bottle was bad, would support that theory.
This was sarcasm!
Thanks.. looks like I got my answer. Not a single bottle rejected!
When the process is powerful enough to blast out the hard to reach places, followed by cleaning and disinfecting that has lead to extremely reliable outcomes across decades, there isn't a reason to reject individual bottles that go through the process.
They most likely do regular checks to make sure the cleaning process is working as designed, as is the standard practice for any automated process. If the samples aren't unclean, then there is no reason to worry about any individual bottle. They check for cracks with lasers because it is fast and easy to do, plus it has the benefits of not allowing contaminants in and reduces the chances of bottles breaking during filling.
On top of that the fermentation process is hostile to bacteria and other contaminants, so even if a minuscule amount was making it through, the beer will finish it off. They don't need to be surgical instrument clean.
I imagine it's not just heat but disinfectant too.
Given glass is pretty inert they could even be using something like bleach or strong acid.
You ever hear of starsan (no-rinse sanitation liquid)? I bet that really helps. Submerging could easily be a thing.
Used to home-brew. Reused lots of bottles for years.
Of course, they need to be cleaned. Most brew shops sell sanitiser which will kill anything that might cause issues.
As far as I know, in the US, recycled glass is recycled, not reused, so they basically waste a lot of energy to melt the glass back down and make new bottles.
Reusing can definitely be done effectively, though. Homebrewers do it all the time with pretty safe chemicals. If you have industrial machines and chemicals, you can probably get the glass sterile, and if not sterile, then definitely close enough.
In Europe they charge 10¢/bottle for simple bottles and 40¢/bottle for the fancy clamp-down style. Then that gets refunded when they are returned. It’s a bit of a hassle because some brewers do not participate, in which case the reverse vending machine rejects the bottle which means you then have to carry it to a glass recycle bin. The brewers that do not participate use a thinner more fragile glass that would be unfit for reuse. So consumers have to stay on their toes and keep track of which brewers participate. Can get quite tricky with the obscure artisinal brews.
Ireland is introducing the same concept for plastic bottles of charging a fee for them then returning the fee in a reverse vending machine. I can’t imagine reusing those. They must be recycling them.
Yeah some states have deposits on bottles/cans that you get back through the vending machine thing, but the only bottles that actually get reused are some fancy milk brands.
Are people not rinsing out recyclables?
I doubt anyone does. I certainly do not. It would not be environmentally optimum to do so.
There is a stat that if you wash a typical dishwasher load worth of dishes by hand (with avg faucet output of 1 gallon/min), you will consume:
- 20 gallons of water if you are a novice
- 8 gallons of water if you are skilled
While a dishwashing machine uses ~4—5 gallons of water. So dishwashers are actually good for the environment. I will clear of any bulk waste before loading a dishwasher, but I do not hand rinse because it would be wasteful.
It’s essentially the same when returning bottles for reuse. People count on the industrial cleaning to do the full job (though I started the thread to get an idea of to what extent it really can be relied on). The refund for the bottle return is the same whether the bottles are clean or dirty, so there is no incentive for anyone to pre-clean them in any way.
In terms of water use dishwashers are good however the detergents available have so many surfacants added that chances are using your dishwasher is poisoning both you and waterways.
I've always given bottles and cans a quick rinse. Stops then from being sticky and smelling, so that's incentive enough for me

You are aware that if you live in a city, or even close to a city, that the water you drink out of the faucet has been pissed in, shit in, jizzed in, bled in, and exposed to countless drugs, right?
I am aware that that happened in Oregon once, and even though the parts per million after one person’s bladder is empted into a tank of thousands of gallons is negligible, they emptied the whole water tank which covered a whole city and refilled it, and sent the guy a water bill for that.
I suggest watching the “how beer saved the world” documentary. It shows how they used filthy stagnant pond water with duck shit in it to brew beer, which was safe after the brewing process. But note the beer container is not part of the brewing process.
The water is not much of a risk. But filled bottles sit in warehouses with rats. Rats urinate on the bottles. This is why Europeans don’t drink directly from the bottle. I’m not sure why Americans are content drinking direct from the bottles.. maybe US warehouses are rat-free.
