Is there any potential risk in making beer/mead in the same way as it was done in historical recipes?

To preface, I have zero experience with homebrewing. I mainly am interested in these recipes specifically because they seem super simple and don't require any specialty equipment.

I enjoy watching youtube channels such as Tasting History or Townsends, where they explore recipes from history. Occasionally they will do an episode on meads or ginger beers or other various alcoholic beverages in history.

Example 1

Example 2

For obvious reasons, these recipes often have a distinct lack of sanitation. Or it will say something to the effect of use a clean bottle which I'm assuming just means boiled and not visibly dirty basically. This is in direct contrast with most modern homebrewing guides which are very adamant about making sure literally anything that touches the beer after the boiling process is thoroughly sanitized.

Is there actually any considerable risk with following these recipes because of the lack of sanitation? Or since these old recipes are typically fermented for a short period of time have low alcohol content is this relatively safe?

And as a followup question, could it become more unsafe to drink over time? Like if I were to make ginger beer and let it sit in my fridge for several weeks or even a couple months, would I be better off just tossing it?

First of all, most brews will probably do just fine if you just clean your equipment the best you can. That was how they used to do it and it does work quite okay. I am sure they also found clever ways to optimize the cleaning, like eg scolding their stuff with boiling water.

Spoiled brews are not really a danger since you can almost always see or smell it very easily if something has gone wrong. E.g. if it has turned to vinegar, you'll smell it, and if bacteria infected your brew you'll see mold and other crap in your product.

The real reason why everyone keeps harping on with the sanitize, sanitize, sanitize mantra is because unless you're making a sugar wash then you'll invest time, materials, and energy into making your brew, and it REALLY sucks if it fails. Of cause if you're making a decent amount of e.g. mead you'd also be out the cost of a all that honey, not a cheap failure!

So really, there is nothing different about those old recipes, they also tried their best to keep things clean cause they realized it yielded better results! Sure, we have super convenient sanitizers now, but most of those could be replaced by more work and boiling water, like in the old days :)

The big risk is probably not that you end up with something that is poisonous without realising, but that it simply spoils and your batch is ruined.

Mould or infection due to lack of sanitisation is typically quite obvious - you have a stinking slimy mess which you have to get rid of.

If you end up with something that looks, smells and tastes like cider or beer or mead or wine then it is likely safe to consume.

Ultimately any fermentation is going to involve a sugary liquid sitting stagnant in a container for a number of weeks. most yeasts (especially the cheap ones) aren't going to kill off other microbes. Obviously I will also tell you: sanitize.

As far as how much you can get away with slacking on sanitizing... You're probably not going to die. It's true that for millennia, mankind had no concept of microscopic life, and sanitation was a lot looser. Most of the time it was fine. I don't know if there have been studies, so I'm going to take a wild, unscientific guess here: doing your first gallon of mead in a cleaned-but-not-sanitized jug is probably not as likely to kill you as spending that money on cigarettes.

but again: sanitize.
