The headquarters of Taittinger are an excellent place to come for a clear, straightforward presentation on how Champagne is actually made – there’s no claptrap about ‘the Champagne mystique’ here. Parts of the cellars occupy 4th-century Roman stone quarries; other bits were excavated by 13th-century Benedictine monks. No need to reserve. Situated 1.5km southeast of Reims centre; take the Citadine 1 or 2 bus to the St-Niçaise or Salines stops.
