I think it’s important to point out that almost everyone drank beer and it wasn’t because the water was bad. It was because they liked drinking beer.

Our modern culture doesn’t like the idea of people drinking beer all day so there has to be some scientific justification to make it acceptable to modern sensibilities.

The percentage of alcohol required to preserve beer for long periods is too high for sailors to be drinking a gallon of it per day.

oofManBang 7 minutes ago
Point of order, beer was stored in a higher alcohol percentage (which is where we get IPAs from) which does extend its shelf life significantly. The gallon was heavily watered down to serve.

Which is basically identical to lite beer we drink today. Hopefully with more flavor, but I don't actually know.

Reading this thread I think the best thing would be if people were forbidden from comment on the history of beer in online forums. Nobody knows anything, yet everyone is shouting their misunderstandings from the rooftops.

The Danish fleet, to take just one example, was completely dependent on a supply of "skibsøl", to the extent that the king started his own brewery to ensure his fleet had a supply. Later kings started a stupid brewing monopoly system in Copenhagen to ensure no breweries went bankrupt, again with the same aim. "Skibsøl" was a big thing in Norway and Sweden, too. The Royal Navy used to serve it, too, before switching to grog.

Yes, weak beer will turn sour, but it takes a lot to make it harmful.

While I agree in general with what you've said, this line is wrong. Strong beer will turn sour too. Acetobacter is good up to 10-15%, it's how we get malt vinegar and wine vinegar. All it needs is ethanol, oxygen, and time.

larsga 6 hours ago
Sure. Hard to get all the details into a comment that's already too long.

In general, however, strong beer keeps much longer than weak beer. However, even if it does sour, that doesn't mean it's harmful to drink.

A few brushes with bad water might have given folk a strong preference for beer, just to be on the safe side, even if most water was safe.

Yes, it can. But infections by harmful organisms is very difficult to achieve. The common spoilage organisms in beer are all harmless to humans. Here's a good overview http://mmbr.asm.org/content/77/2/157.long

Just the hops alone stop pretty much all gram-positive bacteria except Lactobacillus and a few other harmless ones.

Often things that a lot of people do repeatedly for "pure enjoyment" actually has some hidden benefit.

Like for instance, drinking in general. People do it because it's fun, but it can play an important social bonding role.

Exactly. To my understanding any amount of alcohol is unhealthy, but societies have had festivals or other rituals since the beginning, and substances _like_ alcohol play an important role in those.

Water on ships wasn't that clean to begin with. And things were made worse by people maybe not observing good hygiene. Think sharing cups, dipping those in the water, not washing their hands, etc. Imagine that, stored in a poorly sealed barrel on a ship with rats and other pests. Water was pretty bad on ships. People would get sick and weak on longer journeys (malnutrition, contaminated water, rotting food, etc.). A lot of their diseases would spread via water.

Beer had a head start on water because part of the process of making it involves boiling the water and the alcohol slows the growth of most of the pathogens. And it has some nutritional value.

It is my understanding that the yeast in the beer will consume everything it can and that is what keeps the beer preserved, or safe to drink.
poloniculmov 4 hours ago
While yeast will consume most of the nutrients, there's still residual sugar in beer. Hops will inhibit microbial and bacterial growth, but they will not stop it completely.
larsga 3 hours ago
Yes, there is residual sugar, but it's complex sugars that not even yeast that specializes in fermenting sugar can consume. Plus there is alpha acids from hops, as you point out, there is alcohol, pH is low, oxygen is gone, there's a CO2 blanket, etc. So it's a very, very difficult environment for microorganisms. Pretty close to none that cause disease can grow in this environment.

A caveat being and mentioned in the article, that sailors didn't have access to the safe water of lakes and streams, thus beer. And as someone mentions below, it's safer to drink low alcohol beer than months old (untreated) water. I can see why people jump to the conclusion that beer was safer than water...and it makes for good cocktail hour small talk.

As if the water of lakes and streams was necessarily safe. Imagine drinking Thames water in the era before proper sewers. In 1858 (the Great Stink) the Thames stank so badly from feces that parts of Parliament became unusable.

You’d have to go quite far upriver to avoid drinking seawater (since Thames is tidal) even before all the pollution.

Beer was known to go bad on long voyages. So long as the beer held out though there was no scurvy.

Beer does not cure scurvy. Scurvy is caused by a lack of vitamin C, which is not in beer.
0cf8612b2e1e 16 hours ago
Beer staying fresh seems like a proxy for voyage duration. Longer trips means more likely to have run out of beer/vitamin C sources. No beer probably means no dock where sailors could have consumed anything other than highly preserved food.

Someone asked this under 24 hours ago: https://old.reddit.com/r/AskHistorians/comments/1k5ji8i/how_...

But it comes up a good 2-5x a month. I really want to know where this understanding came from.

larsga 15 hours ago
The thing is that water was not really safe to drink, no matter what these people may tell you. There's a reason there are huge aid campaigns all over the Third World to ensure people have access to safe water. Some water is relatively safe to drink, but even in the wild you can get giardasis and other problems from drinking it. The more human beings are nearby, the more of an issue it becomes.

In the time before cars transporting water was not easy, so people usually had to get water from the nearest source. Wells were not necessarily safe, especially because both humans and animals tended to shit pretty much everywhere. Even today well water is not necessarily safe.

But did people know that drinking water was unsafe? Evidence on that is contradictory. They were certainly aware that some kinds of water was safer than others.

And was this why people drank beer instead? Not clear at all. It's completely possible they did it simply because they wanted to, although it was seen as healthy. That was because of the calories, though.

In many places they did not drink beer, however. Scotland and Norway drank blaand (a whey drink), and Eastern Europe drank a lot of kvass. Fermented birch sap and a drink from juniper berries were common, too. Not to mention a weird drink known as rostdrikke/taar/etc depending on language (takes too long to explain).

What I find interesting about this is that nobody seems to care to really dive into the details and describe the situation as it actually was. I realize it's a lot of work, but still.

oofManBang 15 hours ago
I don't really get your point. Water isn't necessarily safe now, either. Just like now, you boil water if you are aware of risk. Just like now, people communicated about when to boil, where to gather water, skinning people alive for messing with the water (well that has perhaps improved a little bit), militaries would regularly poison water sources. And of course, you can find people today who willingly take dumb risks for no explicable reason. All of your uncertainty applies just as much to today as it did in the past.

Water has always been, is, and will be uncertain. But there's so much evidence of awareness of this that speculating people didn't drink water is absurd. Not to mention keeping water sources clean gets much harder with high populations we see today—we have roughly the same amount of water that we did before

Btw, you casually ACCEPTED that people drank beer instead of water when we know this is false. Even on ships (as you would know if you clicked through the askhistorians link under the top of the thread) ships did carry (a lot of!) water—it just wasn't listed as rationed unless supplies ran low. This was both drunk directly and added to the beer to produce the gallon allocated.

Ie you might follow the same rhetorical technique to say "why do you beat your wife? Well, the evidence is uncertain.", even if we have clear evidence you don't beat your wife.

You'd really have to find evidence that people explicitly avoided water to make such a claim. In all situations I can think of there was either certainty it was not potable (ie seawater, poisoned well, flooding, etc) and being unable to boil it.

larsga 6 hours ago
> Just like now, you boil water if you are aware of risk.

People didn't do that, though. As far as I can tell, water-drinking was not particularly common. People went to surprising lengths to produce other forms of drinks, all of them fermented in some way.

> All of your uncertainty applies just as much to today as it did in the past.

What on earth do you mean by that? Today you have clean water from taps all over your house. In the old days, clean water was rare, and you had to carry it home. If you were lucky you could use a wagon, but it was still hard work.

I mean, yes, of course there was risk then and risk now, but the risk was orders of magnitude higher in the past.

> Btw, you casually ACCEPTED that people drank beer instead of water when we know this is false.

You have absolutely no idea what you are talking about. I've worked on this for a decade, collecting archive accounts from around Europe. I can quote you pages and pages and pages and pages of people writing about how they used to drink beer against thirst every day. Read [my book](https://www.brewerspublications.com/products/historical-brew...) for more.

> Even on ships (as you would know if you clicked through the askhistorians link under the top of the thread) ships did carry (a lot of!) water

Buy a subscription to Craft Beer & Brewing and read my article on [skibsøl](https://beerandbrewing.com/skibsol-smoky-ale-of-the-seas/) the Danish style of beer created expressly for the purpose of being drunk by sailors. It starts with the story of the gov't commission created to investigate improving the sailors' beer after the Battle of Køge Bay.

> You'd really have to find evidence that people explicitly avoided water to make such a claim.

I don't claim that people explicitly avoided water, because the evidence is thin and ambiguous. (Seriously, read the comment you replied to!) What I do claim is that people did drink lots of beer for thirst in various contexts (listing exactly which would make this too long). Exactly why they did is not clear, but we do know people thought beer was healthy. Probably they thought it was healthy because it has lots of calories. (This was a time when getting enough to eat was a challenge for large parts of the population.)

> being unable to boil it.

Again, people didn't do that. You don't need to go back very far in time before people didn't have easy access to metal containers to boil in. Long story, [this chapter explains](https://press.nordicopenaccess.no/cdf/catalog/view/238/1292/...).

Based on what? You certainly haven't given any indication of having read what historians have to say.

Granted, that subreddit could be a cabal of people colluding to make us think humans didn't go through a phase of drinking beer rather than water. It seems easier to believe you're trying to justify your own talking out of your ass if you can't respond to specific claims.

> In the old days, clean water was rare

What does this mean? Clean water was arguably much more common than it is today because of industrial contamination.

> What I do claim is that people did drink lots of beer for thirst in various contexts (listing exactly which would make this too long).

Nobody contests this. What is contested is fear of drinking water.

> I've worked on this for a decade, collecting archive accounts from around Europe. I can quote you pages and pages and pages and pages of people writing about how they used to drink beer against thirst every day.

Great! Pay up! I ain't reading your book.

Btw, you don't need metal to boil water. And beer is healthy if you're faced with a calorie deficit; it's loaded with nutrients. Perhaps you should use this as an argument for why people drank beer (allegedly and confusingly instead of water)

> I don't claim that people explicitly avoided water

Yes you did:

> And was this why people drank beer instead?

If you did not mean to imply that beer drinking came at the deficit of water drinking, you should consider rephrasing.

> What I do claim is that people did drink lots of beer for thirst in various contexts (listing exactly which would make this too long).

I have no doubt that someone in history said this, just as they did now; what I find hard to believe is that this was in any way normal or typical. One citation might be more meaningful than this entire thread. If you can provide a source, please do so.

Hell, I drink beer for thirst myself; against all rational judgement. This doesn't imply my tap water is unclean.

I am a historian. This is based on 10 years of reading ethnographic archive documentation of what people used to drink on farms, plus of course wide reading of ethnographic and historical literature on this.

> Clean water was arguably much more common than it is today because of industrial contamination.

Industrial contamination is not the issue. The issue is bacteria and other micro-organisms. This page is very good https://en.wikipedia.org/wiki/Waterborne_disease

This is what toilets used to look like, from a museum in Gotland, Sweden. https://img.garshol.priv.no/photoserv.py?t378684

Now imagine the effect on your well, which usually would be downhill from the houses.

> Nobody contests this. What is contested is fear of drinking water.

Actually, lots of people contest that people used to drink beer, but that's fine. Let's move on.

I agree fear of drinking water is tricky. Evidence on this one way or another is hazy and ambiguous, but it seems to be more a preference for beer. What motivated the preference is again tricky to pin down.

It's easy to come up with quotes showing aversion to water. Just look at the first page of Linné's "A Description of Beer" (actual title in Swedish) from 1749. It says straight out that many kinds of water are harmful and therefore people prefer beer. But it doesn't mean this was a general belief, and there's plenty of evidence the other way.

> Btw, you don't need metal to boil water.

I already linked to a paper on how to boil water without. But it does mean that it was difficult. And people didn't know they needed to. So they didn't.

>> I don't claim that people explicitly avoided water

Quote is missing or garbled somehow.

The alcohol wasnt what made beer safe. Beer was safer than water because to make bear one must use sterile water. So beer at least started out sterile/boiled before it went into the barrel.

larsga 15 hours ago
This is complete and utter nonsense. The water used in beer often had bacteria (and other stuff) but to brew beer you must mash, at 65C for an hour or more, which pasteurizes the beer. Hops protect the beer against bacteria, and the yeast also makes it hard for other organisms to multiply in the fermented beer. Alcohol is one of those ways, but only one.
sandworm101 59 minutes ago
That is modern beer, the stuff made by people who know about bacteria. Prior to modern knowledge, beer recipies were based on trial and error. Boiling the water first avoided many spoilation problems that, today, we know how to prevent through other means.

Again this is stuff you're just inventing because you don't know better.

> Boiling the water first avoided many spoilation problems that, today, we know how to prevent through other means.

You have this backwards. Boiling or near-boiling the water is what's nearly universal now. It was much less common in the past.

> Prior to modern knowledge, beer recipies were based on trial and error.

Correct. However, all beer is mashed. You don't get beer without it. That's a one-hour 65C pasteurization at the very least. As far as we know, all European beer from the stone age until now was made this way. So you can take this part as ordained by the gods of chemistry. So no matter what you do about the water initially, the whole thing will be pasteurized afterwards.

There are still people today brewing traditional beer from recipes based on trial and error, with zero input from modern science. Some of them start with a mix of cold water and malts that they then heat in the kettle. Here's an example of me visiting and brewing with a guy who does exactly that https://www.garshol.priv.no/blog/409.html

If you want I can make you a map of where in Scandinavia and the Baltics people used this method the last 100-200 years. Before that people often didn't have kettles, and so (as far as we know) the water was not heated before brewing (long story exactly why we think so).

Not in the British Navy. Food was very important to morale and they got a lot of it with the best quality they could manage. Meat every day was luxury few people could afford.

Bacteria (and certainly viruses) can survive 80 proof liquor. 1% alcohol is going to have very little sterilization effect.

It's not the alcohol that's supposed to kill bacteria, it's the long boil.
larsga 15 hours ago
First of all, many types of beer were historically not boiled. Quite a few still aren't. The mash, however, pasteurizes the beer.

That, however, doesn't last forever. In the conditions of the 18th century or whatever, microorganisms will get into the beer after mashing/boiling, so the heat treatment only helps for a while. The fermentation really does protect the beer afterwards, but it's a combination of low pH, alcohol, low oxygen, little nutrients, CO2, etc. Hops also help against gram-positive bacteria.

wqaatwt 6 hours ago
Hops weren’t that popular until the 1400-1500s (or not used at all in some places like England) though
larsga 2 hours ago
You're broadly right, but they were popular for most of the period we're discussing.

In continental Europe they were popular from roughly ~1000 onwards (see Behre 1999), in England from roughly 1500 onwards. In African and South American farmhouse brewing they're still not used. So it's a pretty complicated picture.

As the comment made clear, hops are only one component of what makes beer safe, though. Storable, safe beer for travel is documented already in Ancient Egypt.

oofManBang 16 hours ago
The boil does kill the bacteria, but it's not preserved after the boil. At best it's as sterile as water; at worse it spoils faster due to the abundance of nutrients.
xorcist 13 hours ago
That's why it's kept sealed, under pressure. I wouldn't fill a water bottle and let it sit for many months before drinking it ever today. A beer bottle with CO2 atmosphere can sit for a long time.

There may be other reasons to prefer beer where the alcohol is relevant of course, just not for freshness. And freshness could absolutely have been relevant in the choice of drinks to load, together with low cost and acceptance in general.

Wooden barrels were sealed and could handle high pressure. The trouble is that (long story) it was very difficult to get a precise amount of pressure, so people generally didn't even try. There are videos online of cases where people have failed and end up battling a beer barrel spraying beer like a firehose.

Would technology that allows sealing of beer not apply even better to relatively nutrition-less water? Especially boiled water. Anything that can feed off of pottery + water or metal + water or glass + water is gonna take a lot longer to grow than basically any kind of familiar bacteria feeding off beer + any of the above.

I imagine these are largely the same reasons people drink beer today. Spoiler: it generally ain't hydration or avoidance of disease.

1% is not enough to keep bacteria from growing in a beer. In general, more alcohol means it will keep longer, but to be truly safe you need to go quite high. This is a pretty complex issue, though.
