LOADS of bubbles in the raspberry wine (had to give up shaking in the end because it was exhausting me!). No, I've not seen degassing mentioned in the wine books I have (though CJJ Berry does suggest agitating the wine, but without going into detail). So glad I didn't bottle it. No chance of me putting the wine in a warm place because 15 degrees centigrade is as hot as my flat gets! Will keep shaking another day!
