Gewurztraminer (also known as Gewürz) is an aromatic wine grape variety that performs best in cooler climates. Gewürztraminer is a variety with a pink-to-red skin colour, which makes it a "white wine grape" as opposed to the blue to black-skinned varieties commonly referred to as "red wine grapes”. The grapevine is vigorous, even unruly, but it hates chalky soils and is very susceptible to disease. It buds early, so is also very susceptible to frost, needs dry and warm summers, and ripens erratically and late. Its natural sweetness means that in hot climates it will not develop enough acidity to balance the huge amounts of sugar. On the other hand, picking early to retain the acidity, means that the varietal aromas do not get a chance to develop, and these aromas may be further diluted by overcropping in an attempt to overcome the low yields.
