Scientists Discover the Secret Bacteria Behind Artisan Cheeses – and They May Be Good for Your Health

Researchers found that artisan British cheeses host distinct bacteria that shape flavor and texture during aging.

In cheeses from Nettlebed Creamery, microbial communities changed over time, with one hay-aged cheese showing greater microbial diversity.

The study also found lower lactose and species such as Streptococcus thermophilus, Lactococcus lactis, Propionibacterium freudenreichii, and Penicillium candidum, which may have probiotic or prebiotic potential.

The findings suggest traditional cheese may offer benefits beyond taste by carrying microbes and compounds that could support gut health.
