In Argentina Mario González (Senior), director of La Riojana Cooperativa has tried using sheep. González has used many sustainable methods to maintain the vineyard. They pull up the weeds growing in the vineyard by a Texel sheep flock of around 2000 animals, instead of doing it with machinery
Comments made from Britain were: Jerry Garner: Having only 3 vines and a flock of 30+ sheep (used to be 70+) I cannot say I dared introduce them to the "vineyard"! Do any members recall the Shropshire sheep society had a stand at Fruit Focus 2 or 3 years ago? They claim that this breed does not bark apple trees etc like other breeds tend to. During the dormant season sheep should not directly damage vines provided there is sufficient grass and the necessary mineral licks are supplied. Certainly, well established vines on a high wire system should be OK (I recall the vines at Stanlake Park were high wire). Sheep are very susceptible to copper toxicity (except for a rare breed from the Orkneys) so Guy's advice about copper sprays is good. Sheep and even goats could be really useful if you hate pruning. Many years ago we took an early autumn holiday in Formentera (Balearics). The vines there were goblet pruned and looked like a blackcurrant bush. I was horrified to see hobbled goats and sheep loose in the vineyards until I realised they were nibbling the younger wood back to about 2 buds! Having kept sheep since 1980 I can confirm that the first wish of any sheep is to die. The shepherds job is to postpone that moment for as long as possible!
From Wallingford, Bob Nielsen was less optimistic: Everyone I've talked to says looking after sheep is a hassle. They spend all their time finding new and imaginative ways to kill themselves. Not easy care like pigs who need nothing more than an electric fence and never get ill. However pigs are not recommended for a vineyard unless you're grubbing up - in which case they are excellent! They're also excellent at digging out brambles - they love the roots.
The wine guru Stephen Skelton was equally pessimistic
I used my sheep in the '70s and yes they work, but tend to rub against posts
and vines. In the summer they will deleaf but again, put their hooves up on
the wires and push posts over. Need fencing up tightly and moving on
regularly. Not really worth the aggravation and extra work moving fences
However, from Giffords Hall in East Anglia there were more favourable comments
We have successfully overwintered Hebredean on the vineyard for the last six years. The advantage are one less herbicide spray, the ability to put organic matter back into vineyard, two less mowing passes and shorter grass than you would ever be able to achieve with a topper at a time when you really need to heat up the soil.

From Cornwall, some success was also noted. Jamie King (Jays Farm Vineyard) has grazed sheep in his vineyard for many years and Engin Mumcuoglu [email@example.com] grazes a specially designed (!) small breed of sheep at his Padstow vineyard. At Camel Valley, success was mixed. Bob Lindo commented that We had 300 ewes here and the main problem is they rub themselves up against posts etc and loosen them. The secret is to set graze them in smaller areas and rotate them quite quickly with a judicious use of electric fencing.
