Zero dosage means zero apology: no sugar added at the end, nothing to soften the edges or hide behind. Naveran's Brut Nature is the driest wine in their lineup and the most revealing, which is only possible because the family grows every grape themselves — 110 hectares farmed organically in Torrelavit, up in the high Penedès about half an hour from Barcelona. The blend runs Macabeo and Parellada for citrus and lift, with Chardonnay for flesh and Xarel·lo for backbone, and it's vintage-dated and rested a minimum of two years on the lees. What lands in the glass is taut, chalky and bone-dry. Estate Cava made with actual conviction.
