Wine growing author Gillian Pearkes, who was considered an authority on wine growing in England was contacted for advice. Over a two year period in the early 1990’s visits were made to Gillian’s vineyard, Yearlstone Vineyard, where Gillian gave instruction on how to grow and look after the vines and the wine making process. Many of the older English and Welsh vineyard owe their existence to the late Gillian Pearks.
