Enfys Wyse, 57, who owns a tearoom in Cenarth, Ceredigion, said she had noticed a change in milk prices over the years but claimed it “hasn’t been too bad”.
“Over the past 10 years, it’s gone up £35 a week.
“In the summer, when we’re really busy we go through 10 to 12 two litre [bottles a day] and then in the winter, we go through five to six,” she said.
“We’ve got to use milk for coffee, to do pancakes. You need it, you’ve got to use it, whatever the price is.”
Referring to the increase, Wyse said she thought it would have been more.
“You need milk, so you don’t mind paying extra for what you get.
“I think it’s quite low really.”
As winter approaches – the time of year when costs can be at their highest for farmers – NFU Cymru said there were “renewed concerns that tight margins are being further squeezed”.
They are encouraging the Welsh government to help give stability to the sector which they say is worth £929m to the economy.
Farmers Union Wales said a clear long-term strategy was needed for Wales “to develop its dairy industry to overcome the volatility of milk prices and input costs”.
The Welsh government said: “We recognise the particular pressures facing dairy farmers, driven by global oversupply.
“We are committed to the dairy sector in Wales and through out agricultural schemes offer a range of support suitable for dairy farms to enhance their financial and environmental performance.”
It added that its £1bn funding commitment was providing certainty to farmers alongside the Sustainable Farming Scheme, which is available to all farmers.
