I have been arguing with my friend who is German about what is a beer and what is not a beer, and what is an ale and so on. Basically everything revolving around the German Purity Laws. One thing he keeps telling me is that real german breweries don't add yeast and require natural yeast. I could see that maybe way back in the day but for the past 100 years it just doesnt make any sense. Don't they at least pitch on top of an old beer or something. Feel free to chime in and put your input in, because according to him Sierra Nevada is an ale and not beer.
 
I don't really know what is meant by requiring natural yeast. Do you mean like wild yeast?

As far as Sierra Nevada, if you're referring to the pale ale it is an ale. I think a lot of people consider lagers beer and ales ale; if that makes sense.
 
Ale is beer. The German law at the time said beer could only have barley, hops, and water (they didn't know about yeast at the time, and it likely was added to the beer via their stiring sticks).

From your friend not to be an EAC.
 
Your friend is wrong. Reinheitsgebot originally allowed only water, hops, and barley, but was amended after Pasteur to include a fourth ingredient, yeast. Modern german breweries have meticulous control over their yeast.

The terms "ale" and "beer" have meant different things to different people at different times, and they still do. Typically, however, the contrast is between "ale" and "lager", with both being types of "beer".
 
Yeah I tried to tell him that yeast is needed for fermentation but now he is trying to tell me there are wines that don't have any yeast added to them. Which i guess makes them the Virgin Mary of Wines.

:) If you can imagine a world ignorant of yeast but with the knowledge that beer can (might) ferment for you, it's easy to understand why people were so superstitious! I think some areas in Germany actually banned brewing during the summer not knowing that it's the temperature that changed the taste. The purity law is based on trying to make sense of a puzzle for which pieces were missing! Now it's tradition which means a lot, at least to me.

Grape skins are known to hold wild yeasts. But what is his point?

The grape skin is home to many organisms and yeast is one. You needn't pitch must to get a fermented wine and they can be quite good as I understand it. Most modern brewers and winers ( that is indeed a zing) don't take chances w/ mother nature and pitch cultured yeast.

Lambic beers are beers that are fermented by wild yeast and in inoculated by incidental contact with organisms in the atmosphere by means of a rest period in an open topped vessel ( coolship). It's a widely accepted practice and happens everyday by modern brewers and on purpose. What you get in the end is unmistakable with any other beer. In other words, when you are drinking a lambic beer, you know it. As far as most common styles go however, pitching cultured yeast is a must (nyuk, nyuk, nyuk)

The "purity law" was based on trying to keep commonerers from using wheat to make beer and keepin the wheat crop in the hands of the upper class so they could have bread and beer (secondarily) from the wheat. The only "purity" they cared about was making sure that beer did not contain wheat. This was not a high minded kind of thing. It was all based on privelege for the upper classes.
 
T he story of how hopped beer came to replace gruited ale is a complex and convoluted one, with origins in both the Protestant Reformation and the Industrial Revolution. An anti-gruit campaign, similar in scope and absurdity to our contemporary War On Drugs, fed off the anti-clerical and anti-pleasure hysteria of the Protestant Reformation, and coincided with the violent persecution of herbalists as witches and herbs as dangerous substitutes for "scientific" medicine in the sixteenth and seventeenth centuries. It didn't help that gruit blends in many parts of northern Europe were exclusive monopolies of the Church. All brewers in those areas were forced to purchase their gruits from specially licensed monastic houses at highly inflated prices, which probably did more to enflame anti-clerical feelings than anything Martin Luther ever said.

It's also important to remember that most brewers throughout the Middle Ages and into the Renaissance were women. In England, at least, the competition between "modern" beer brewers and makers of old-fashioned ale took on aspects of a war between the sexes, though it was also about urban vs. rural and large-scale vs. small-scale production. Studies of tax records from the period suggest that, in more rural areas, the vast majority of commercially produced gruit ale was made by part-time brewsters or "alewives"--female homebrewers who sold their surplus ale, typically advertising a new batch by sticking a broom out the window. As long as brewing remained a minor, local activity--a source of seasonal, supplemental income for farmers' and tradesmen's wives--nobody cared. But when it became obvious that there was serious money to be made, men began elbowing in. The fact that hopped German "bier" was exempted from the regulations protecting the brewsters' guilds simply provided the fulcrum. A vicious propaganda campaign stereotyped alewives as filthy, slatternly cheats who never missed a chance to adulterate their brew.

T he much-lauded German Beer Purity Laws have their inception in anti-gruit and anti-homebrew regulations of this period, and formed part of the same irrational phobia toward the (darker) Other that culminated in the Nazi holocaust. To this day, many beer purists insist that any addition of non-grain-derived sugars--much less herbs and spices--makes a brew fit only for the ignorant, unwashed masses. And of course the wave of Protestant-instigated intolerance peaked in the temperance movement of the late 19th and early 20th centuries. The resulting prohibitions were the nail in the coffin for most local brewing traditions. Nowhere was the intolerance as strong as in the Prohibition-era United States; our modern centralized, homogenized corporate brewing landscape is the result.

Fortunately, the tradition of homebrewing was never completely eradicated from the farmstead, especially in the more remote corners of Scotland (where heather ale was the persecuted national drink) and in parts of Scandinavia. But on this side of the Atlantic, contemporary homebrewers have learned (or relearned) quite a bit since the days of Prohibition, when exploding bottles and "off" batches were regarded as normal, occupational hazards of brewing at home.

There's no simple explanation for why hops won the war in Britain, where malting and ale-brewing traditions were so elaborated and so firmly entrenched in the culture. I suspect that the sedative properties of hopped beer were a big part of the answer, however. Working people had long been in the habit of drinking weak ale--"small drink" in the parlance of the day--from the second running of the grain (4). The prolonged boiling meant it was much safer to drink than water. Alcohol content typically ranged from 1-3%, and given the heavy grain bills common with less efficiently sprouted malt, this weak ale would have been highly nutritious--a major source of B vitamins, among other things.
