Terroir

• In the northern part of the Rust municipal area, calcareous brown soils (Kalkbraunerden) dominate, with a loam overlay of varying thickness that increases toward the Neusiedlersee.
• In the southern part of the Rust municipal area, siliceous soils dominate, formed from weathered schist.
• Rust lies within the Pannonian climatic zone, characterised by dry, hot summers and dry, cold winters.
• A particularly distinctive climatic factor arises from the high rate of evaporation from the Neusiedlersee — a very shallow, warm steppe lake — combined with warm and consistent autumn temperatures.
• When the cool morning mist that rises from the Neusiedlersee settles on the vines, it creates the ideal conditions for the development of Botrytis cinerea.

• Botrytis-affected bunches are hand-selected in several passes, with suitable portions deliberately broken out, a practice from which the name Ausbruch is derived.
• The vineyards are managed according to the high-trained trellis system standard in Austria, with predominantly manual care including pruning, canopy management, and green harvesting.

• The wine displays a gold to amber-yellow colour, attributed to the elevated glycerol content resulting from noble rot.
• Through noble rot, the grapes shrivel and dry on the vine, leaving behind highly concentrated aromas and sugars, resulting in a raisin-like shrivelling with concentration of acidity, sugar, extract, and aroma.
