Boutari, the Macedonia-founded Greek wine house (1879), opened its Santorini facility in 1989 at Megalochori. The Santorini cellar contributed to the international launch of Assyrtiko through the 1990s; the Nykteri bottling is a long-running reference for the night-harvest style.
Tasting: Daily tasting flights at the Megalochori winery year-round; multi-wine flights pairing Boutari Santorini, Selladia and Nykteri with Greek cheeses and meze plates.
Signature wines: Boutari Kallisti Santorini Assyrtiko, Boutari Nykteri, Boutari Vinsanto
Tip: Boutari Nykteri is widely distributed in export markets and ages well at 5 to 8 years from vintage; the standard Boutari Santorini is the budget-friendly entry into the PDO.
