use of helveticus starter

[broombank]

does anyone know which commercial British cheddars use a Helveticus starter? Use of this starter imparts a sweeter fruitier element to the taste. Artisanal producers don't use it. It's the big commercial dairies which do but i can't find out which ones. I am required to taste a helveticus started cheddar as part of the Academy of Cheese part 2 training course.

Commercial L. Helveticus is an adjunct starter culture (LH 100 or Flav 54) which doesn't produce enough lactic acid so it is paired with a starter culture that produce lactic acid (Flora Danica, MM 100 or MA 11). I think Old Winchester fits the bill. I have a hunch it has L. Helveticus.

Pitchfork, Montgomery, Cheddar Gorge and Westcombe cheddars probably have L. Helveticus because they use raw milk.
