5 g Package.  Originally called 71B-1122, the Narbonne strain was selected in Narbonne at the Institut national de recherche en agriculture (INRA) by J. Maugenet. The selection was designed to isolate yeasts that would produce a fruity yet fresh character in wine that would live long after fermentation.

Oenological properties and applications
The 71B strain is a rapid starter with a constant and complete fermentation between 15° and 30°C (59° and 86°F) that has the ability to metabolize high amounts (20% to 40%) of malic acid. In addition to producing rounder, smoother, more aromatic wines that tend to mature quickly, it does not extract a great deal of phenols from the must so the maturation time is further decreased.

This strain can be sensitive to competitive factors and may have difficulty competing with wild flora.


Ask a Question
  • We are looking for production quantities of lacking 71B. Is there a price per higher quantity?

    We do offer 71B in 500 g quantities for $44.99 ( Link Here ), and also have access to 10 kg packages for $499.99 if you require larger production quantities.

  • I have used this for black raspberry wine with good luck, what other yeast would be close or even better?

    BM 4X4 and D47 are both great! We've used them both and enjoy the outcome! Cheers!
