Apple Cider Vinegar and Vital Wheat Gluten, Why Add These?

Why you should consider adding these ingredients for your next Fresh-Milled Flour (FMF) bread.

Challenges of FMF over AP Flour

Since fresh-milled flour includes all the bran + germ (sharp particles + oils) and often has higher enzymatic activity than aged white AP flour, it tends to:

  • Cut gluten strands (bran acts like tiny blades)
  • Soak up water unevenly (bran hydrates slowly; dough can feel “dry then suddenly slack”)
  • Make dough feel weaker/stickier at the same hydration
  • Shorten your window between “perfectly proofed” and “overproofed / collapses”

So additives like VWG and ACV are basically “stability tools” to offset that.

Rule of thumb:

  • VWG = more lift/structure.
  • ACV = more stability/handling.

Vital Wheat Gluten (VWG)

FMF has bran/germ that interfere with gluten and make loaves rise shorter/denser. VWG:

  • Boosts dough strength + gas-holding → taller loaf, better oven spring
  • Improves crumb → less dense/crumbly, more sliceable
  • Adds tolerance → less collapse/spread if hydration or proof is a little off

Default recommendation for VWG: 3% of flour


Apple Cider Vinegar (ACV)

FMF can get stickier/weaker as it ferments (more active enzymes + whole-grain particles). A tiny bit of ACV:

  • Slightly lowers pH → helps keep dough from turning slack/gummy over time
  • Tightens handling → less spread, cleaner shaping
  • Supports structure indirectly → helps the gluten you do build hold up longer

Default recommendation for ACV: 0.5% of flour
