The winery says:
This Riesling hosts bold aromas of orange blossom and lime zest accentuated with hints of lemongrass. Its fine bubbles are elevated by a focused acidity and a lean crisp body. A plucky front palette bursts with Granny Smith apple and key lime integrated with structural undertones of minerality. Lean and precise. First 48 case disgorgement. 4 g/L dosage.
This, by the way, spent over 4 years on the lees, far longer than most Champagnes twice or more its price.
How good is this? Well, we just put another bottle in the fridge.
