71B: For nouveau wines
71B was isolated by the INRA (National Agricultural Research Institute) in Narbonne, France. 71B is known for making blush and semi-sweet wines with a 'fruit salad' character. Long-lived aromas are due to its production of esters and higher alcohols. 71B also softens high acid musts by partially metabolizing malic acid.

What do you make of Joe's point that "this yeast is a laboratory product made in Holland from a tomato base"? [I mean, besides lauding indigenous yeasts.]
Is there anything wrong with using "industrial yeasts" generally?
Regards, Bob

Wines made with 71B are not my favorite, but he seems to be knocking the entire wine yeast industry and winemakers who inoculate with pure strains. To me it’s just another choice that a winemaker has in his/her arsenal to produce the intended style of wine.

I'll go along with using "indigenous", but the choice of yeast is a reflection of both the wine and the winemaker. The choice of yeast can effect acid levels, alcohol levels, residual sugar, aromas and mouthfeel. The winemaker can choose to produce wine in a certain style and the choice of yeast type is one of the important variables he/she can control to obtain his/her goal.

One could make the argument that the use of indigenous yeasts is as much a part of terroir as any other factor. One case that can be made against the use of any commercial yeast strain is that it will in part mask the terroir, to whatever extent that it dictates the character of the wine (and, if it doesn't dictate the character, why are we purchasing it in the first place?). In that sense, it's a lot like using new oak in vinification: while it can have salutary effects, it runs the risk of dominating the essential character of the fruit itself. Yes, using indigenous yeasts is risky, but who ever said that winemaking was supposed to be free of risk?

How about to save a stuck fermentation?
