Why will contaminating bacteria make wine sour while pure yeast will not?

Answers

Answer 1
Answer:

Answer:

The bacteria can make the wine sour but the yeast will not. Yeast can grow in the presence of air or in the absence of air. But alcohol will only be made in the absence of air known as Fermentation.

It does not take place in an open container. Certain contamination with bacteria can convert pyruvate to acetic acid instead of alcohol which gives sour taste to the alcohol.

So adding yeast does not makes the alcohol taste sour but the contamination of bacteria can.

DID NOT COPy

The Asian Tsunami of 2004 was located in Indonesia. The Earthquake epicentre (where it started) was in the West Coast of Sumatra.

It was a destructive plate margin, which is where the less denser plate (continental) subducts into the oceanic crust. It moved down into the mantle and moved so sudden, it caused a lot of water to be displaced.

This triggered a tsunami of 30m high.
