Gutedel (literally, taste noble) is the local dialect word for the grape variety chasselas, a non-aromatic (i.e. not like sauvignon blanc or gewürztraminer), lemony, pear-like white. Usually it’s made in a dry style and not dissimilar to a light vibrant un-oaked chardonnay from Chablis.
Heugumber means grasshopper (many years ago, after they converted to organic farming, the Ziereisens noticed more little grasshoppers in the vineyards). This is dry, fresh, and alluring with the time on the fine yeast lees giving a doughy/yeasty and grilled nut nuance to the pear, citrus, hay and wet-stone characteristics. This wine ages very easily for a few years but is absolutely delicious straight out of the blocks.
