You can also hold the bottle firmly behind one hand and stand up straight and pour the wine slowly, which is especially polite.
Don't fill the glass with red wine, pour it into one third of the glass, so as not to shake the glass when holding it and spill red wine.
Immediately after pouring the red wine, turn the bottle mouth back to prevent the red wine from flowing out, then gently wipe the bottle mouth with a cloth and cover it.
