Old fashioned milk in glass bottles, where the cream rises to the top, appears to be making something of a comeback.
Taw River Dairy at Sampford Courtenay near Okehampton in Devon, which produces ethical, sustainable milk, says interest is growing all the time and some shops which sell it have had to invest in a second fridge to keep up with demand.
Watch 'A Lot of Bottle'
Sam Bullingham believes in doing things the old-fashioned way. His small herd of 50 cows are allowed to raise their own calves naturally, which he believes is a more ethical, sustainable method.
Sam continues, "We do reduce our yield by leaving the calves with the cows, possibly by 500-1000 litres a cow per year but we see that as an investment in the future because then the calves are higher quality when they come into the herd themselves."
The whole milk the dairy produces is pasteurised but not homogenised so the cream separates and rises to the top, unlike most of the milk we get from supermarkets these days which is homogenised, the fat is broken down and doesn't separate.
Sam's milk has become so popular, some retailers have had to invest in a second fridge to keep up with demand.
One shop and cafe in Chagford on Dartmoor sells 240 litre bottles a week - they serve it in their coffee too.
Taw River Dairy is trying to crowdfund a new electric delivery van to make the business greener and has taken on more land so they can expand the herd to meet demand as interest in more ethical farming methods continues to grow.
