There is a pretty well known site ...cough...stormthecastle...caugh... that most newbies land on that does advise using raisins. It WILL add nutrients. Wine does not need nutrients for a reason, grapes have the literally perfect nutrient profile for fermenting yeast. However, a few raisins are not the same as a vat of grape must.
Choosing yeast:
- K1-V1116 is a very good first batch choice, it is a hardy yeast that it’s near impossible to screw up.
- skip EC-1118, it is the monster beast of mead yeast, it will eat through anything, but it is extremely energetic and you’ll likely blow the delicate flavors out the airlock
- D47 is a good generic yeast, little more finicky than the K1
- 71b is an important one to remember if you are working with apples at all because it is able to process the natural acid in apples and lessen the bite you can get
