Trawenagh Bay
The Donegal conche
Trawenagh Bay is a conche in County Donegal, in the north-west of Ireland. Its enclosure holds plankton and nutrients; it is left fully exposed at every tide. La Famille Boutrais raises Ostra Regal and Sentinelle there.
Fresh water from the streams
Small streams provide an inflow of fresh water. It is this enclosed layout that makes it a terroir of the first order.
