With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: GHB is also produced as a result of fermentation and so is found in small quantities in some beers and wines, in particular fruit wines. The amount found in wine is pharmacologically insignificant and not sufficient to produce psychoactive effects. The addition of Monosodium glutamate (MSG) can retard these amounts as yeast cannot differentiate between this and sugars during fermentation, and attempt to feed on both. the enzymes produced by anoxic yeast cells convert sugar to GHB, yet are unable to affect the MSG, resulting in lower overall levels of fermentation.
text_B: Does it sound like MSG could be a valid substitute for sugars in the natural fermentation process, perhaps enabling poor-quality grapes to produce better wine than normal?
NO.
