I agree get the St Helen's Farm milk. One reason it is better than Delamere is due to freshness. The goats are milked and the milk goes straight into a bulk tank and then from the tank to be processesed in the dairy.
Delamere buy in all their milk so it goes into the bulk tank and gets collected by a tanker, either daily or every other day, from the tanker into the dairies bulk tank then processed.
St Helens do buy in from other farms as well but with 4,000 milking goats it is a good chance that the liquid milk is from those housed next to the dairy.
