alt Hacker News> Am I here to read authentic humans because I value authenticity for its own sake (like preferring Champagne instead of sparkling wine)?
Mate, Champagne is a sparkling wine. In French you can even at times hear people asking for "un vin mousseux de Champagne" meaning "a sparkling wine from Champagne" instead of the short form (just saying "un Champagne" or "du Champagne").
Now, granted, not all sparkling wine are Champagne.
The Wikipedia entry begins with: "Champagne is a sparkling wine originated and produced in the Champagne wine region of France...".
I drank enough of it to be stating my case, of which I'm certain!
P.S: and btw, yup, authentic humans content only here, even if it's of "low quality". If I want LLM, I've got my LLMs.
Basically you have Cremant type sparking wines which are produced from other regions of France besides Champagne. It is just like Champagne just that other French regions like Loire, Alsace, Bordeux etc are not allowed to call it Champagne.
So just like Armanac's are like Cognac's for lower price, good Cremant will be cheaper and more enjoyable that cheaper Champagne (I've not had any really expensive Champagne).
Then you have Cava from Spain which is similar process to Cremants and Champagne. The difference would be in type of grapes used. A friend of mine swears by Cavas just like I swear by Cremants from Loire region. However my wife hates Cava.
Then Proseccos from Italy again are similar, but quality varies more.
After that we get into more questionable cheaper sparkling wines which usually means some sort of out of bottle insertion of CO2 and even worse version include some other modifications such as sugar.
In general to avoid literal headaches you want BRUTs. Anything semi-sweet or sweet is suspicous.
Again I am not a full wine expert but this is mostly years of ahem experience.
