Incredibly intense wild herb and berry aromas plus flinty energy on the extremely focused, medium-bodied palate. Then a giant wave of stony minerality washes over you, almost knocking you off your feet. So filigreed and brilliant in the almost endless finish. Still so young, this great dry riesling masterpiece needs decanting and large glasses if you want to drink it young. From biodynamically grown grapes with Respekt certification. Drinkable now, but best from 2026. - Stuart Pigott

Rebholz's 2023 Kastanienbusch Riesling GG is a fascinating and highly promising wine already at this early stage. It exhibits a delicate, spicy, clear, zesty and pure bouquet of red rock and herbal notes, and it's very precise and elegant, also coolish. Savory and lush on the palate, this is a filigreed, very fine and elegant Kastanienbusch with a medium to full body weight and lots of stimulating layers. The acidity is crystalline and saline, and the mineral expression is very authentic and absolutely gorgeous. This is a giant in a quiet way. Tasted at the Rebholz Kastanienbusch/Christmann Idig/Wittmann Morstein vertical tasting in Westhofen in August 2024. - Stephan Reinhardt

(VN 94-96 points) The 2023 Riesling Birkweiler Kastanienbusch Grosses Gewächs grows on Permian volcanic formations. A hint of passion fruit sets a tropical note on the nose, quite aromatic with a proper crackle of flint. The palate is juicy and has a darker aspect, reminiscent of Reine Claude skins, yet it maintains a lemon edge. Riper fruit glimpses through on the finish, revealing juicy peach and ripest nectarine with a gorgeous bitterness that makes the mouth water. (Bone-dry) -- Anne Krebiehl MW

The Rebholz family's specialty is actually Pinot Blanc. However, their top vineyard, Kastanienbusch, with its ancient Rotliegend soil, can also produce exceptional Riesling. This wine serves as a prototype for Palatinate Riesling: powerful and crisp, yet still impenetrable in its youth. It exhibits spicy notes of white pepper, lemon pepper, lemon peel, and peach stone, while still carrying the 'baby fat' with a hint of yeastiness and smokiness. The acidity is ripe and still prominent. Difficult to access, but undeniably powerful. The length stretches like a tattoo.

A savory version, with impressive depth and length -- and just beginning to unfurl. Dry apricot and bitter spice notes mingle with zesty peach skin and salty mineral elements, plus snap pea, spring onion and smoky petrol details. Captivating and complex, matched to tangy acid verve and quinine bitterness that echoes on the long finish. Best from 2026 through 2040. - KB
