If champagne grapes don't grow in your region, switching to sparkling apple cider, is kinda the point here. Being recalcitrant and "saying see see muh chocolate bar costs more this isn't working," is rather missing the point entirely.
[pedantic] Champagne is not a type of grape, it is a very specific region of France. Champagne as you're thinking of, is a sparkling wine only made in the aforementioned region, typically made with pinot noir, pinot meunier, and chardonnay grapes as the primary grape and various yeasts giving it its specific bubbles. So if a sparkling wine comes from anywhere other than Champagne, France, it is not champagne, merely sparkling wine. [/pendantic]
