Scharffenberger Brut

Cost: $20
Smell: Sweet grapes
When it touches the tongue: Mild pear flavor
Aftertaste: Mild sweetness, grape mixed with pear.

Overall: This is a pretty mild one, not super tart or sour or even super sweet. The one thing that really stood out to me was that the bubbles were not overwhelming. They were light and crisp. They sort of fizzled out quicker than I prefer, but that just means you should drink faster. This would probably be a good crowd pleaser since you never know what people prefer.

Humberto Canale Extra Brut

Cost: $15
Smell: Rich grapes
When it touches the tongue: Juicy berry
Aftertaste: Sweet (tiny hint of tart) grapes. Very dry.

Overall:  It's very light. The combination of fruitiness & dryness is awesome. It's not sweet in a sugary way, just a rich fruity way. Alcohol taste is barely detectable. This would be good in a mamosa too!

Louis Bouillot Perle de Vigne "Grande Réserve" Brut

Smell: Bitter grape
When it touches the tongue: Sour, tart grape
Aftertaste: Bold & very tart
Overall: I was not a fan. It had a super tart aftertaste that was just too much. The only sweetness seemed to come from sugar.

Croser Vintage Piccadilly Valley

Smell: Watery grapes, sweet
When it touches the tongue: Noticable acidity
Aftertaste: Tart, almost bitter, grape
Overall: I decent sparkler, but not one I would get again. It was very acidic and had a tartness (not sweetness) that was not as pleasing.
