Wait until after fermentation. Once it is ready to bottle/keg I add my spices for 3 days... if it is your first time taste everyday and cold crash or package once you have the flavor you want.
Just finishing a batch as well. Kirklands Apple juice and notty.
did trial batches of notty and 71b and nottyhas more apple flavor, slight sweetness and less wine taste
Wife told me to get a hobby.... I started brewing 1 gal batches .... continue to improve and get new equipment. Currently brew on the unibrau and making great beer
Agree with all of the above as well.
look at your set-up and where you want to go and then decide which steps to take.
I went temp control then all grain then electric Within a year and each one helped improve my beers. After that came the kegerator which made Packaging so much easier.
