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.
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?
