Welcome to ELR @IA1. As others have stated, the length of the steep depends on the recipe. Fruits a week or so, bakeries, and some custards 2-4 weeks, heavy custards 4 weeks, tobaccos/NET’s even longer.
Never uncap, as if you can smell the flavors, while uncapped, you are LOOSING flavor molecules/compounds = less flavor.
Cap’m, steep’m, and enjoy.
Very good advice from everyone, very much appreciated, very nice to be on this forum and thanks again
You’re welcome @IA1, and please remember, all of this is our ADVICE, so you could always TRY a few (small) samples, in 10ml bottles. Leave one capped for a month or two, the other uncapped, and see what YOU think at the end.
About the only time I can remember “venting” juices, were when I had HIGH levels of flavors that were alcohol based, but even then, not sure what I vented more, flavor molecules OR the alcohol LOL.
Hi mate, yes I will do a small sample first and make notes, thanks again
