It’s too hot for bare feet, but that doesn’t mean you can cook a fry-up on the path outside your house. A frying pan is a much better tool for the job, because it conducts heat far more efficiently.
Just because something is sweet doesn’t necessarily mean it is sugary. There are a number of molecules that taste sweet. To understand how and why takes a little bit of chemistry.
From my years researching wine chemistry and wine oxidation, I know making every attempt to minimise contact between wine and oxygen is vital. Sealing the bottle is essential.
