... "A new winery has just been completed, with building work still in progress. The design is superb, with the most gentle handling of grapes, the use of gravity for transfers, and enabling maximum cleanliness and hygiene to be maintained."
..."Registration to ISO 22000: 2005 is a great achievement and is the equivalent of BRC or IFS accreditation. The high quality of the wines is undeniable, the winery equipment is of the highest order, and the systems and procedures are secure."
