Ata Rangi was founded in 1980 by Clive Paton on the free-draining alluvial gravels of the Martinborough Terrace, at the southern end of New Zealand's Wairarapa. Crimson draws chiefly on younger estate vines and parcels declassified from the flagship, grown across shallow, stony soils over deep gravel that impose low vigour and small crops. Farming is sustainable and increasingly hands-off, with the Paton family running extensive native restoration through Project Crimson, after which the wine is named, having planted more than 75,000 trees on their Bush Block. Ata Rangi describe the 2024 growing season as arguably their finest in 45 years of growing grapes, a warm, even ripening year giving fragrant, well-balanced fruit.

Fruit was hand-picked and largely destemmed, with a portion of whole bunches retained for aromatic lift, then given a short cold soak before wild fermentation in open vessels. Cap management was gentle, favouring hand plunging to keep tannins fine, and the wine was pressed at a light-to-moderate extraction. Malolactic fermentation ran through the following spring in barrel. Crimson is a deliberately approachable, earlier-drinking expression, matured for a shorter period in French oak with only a small proportion new, so that perfume, red-cherry fruit and crisp acidity remain to the fore rather than oak character.
