I generally find my homebrew wine (just from a regular kit) has a soapy kind of aftertaste. I'm wondering if this might be down to fermentation temperature or something, I'm taking as many precautions as possible sanitation-wise and folowing instructions to the letter

"...I suspect you’ve got a fatty acid issue caused by your stuck/sluggish fermentation. S. cerevisiae can emit fatty acids when under fermentative stress..."
Stuck fermentations can be caused by a lack of dissolved oxygen in the first few days of the fermentation. When you add your wine to your fermenter give it a good shake to help dissolve some oxygen and get a healthy start for your yeast.

1Too little nutrients and low pH can cause stuck fermentations, as well.– valverijMay 18, 2015 at 14:42

very true, but a kit should provide all nutrients and the pH required.– Mr_road ♦Jul 2, 2015 at 16:48

Thanks for the advice! Just got back into the brewing game so I'm hoping things will improve!– AndrewNov 10, 2015 at 22:23
