made my second batch, used about a cup of light brown and regular sugar and boiled it with apple juice came out pretty caramely and apples and a vanilla bean in the primary. smells kinda like a vanilla chi tea. im gonna aerate like you guys told me to, should only aerate it during the first week or so? i got some yeast nutrient and i used alittle, i put some in my hand and tasted it and it taste like crap... dont think im using that stuff anymore, is that stuff even necessary?
up to the 1/3 break aeration is normal however definitely not past the 1/2 sugar break.
Yeast nutrient isn't for your tastes but the yeasties. The yeast will eat up most of the nutrients you put in (if you dose it properly) so the taste won't transfer.
Is it necessary?... no
Recommended... absolutely
without it your fermentations will be slower, increasing the risk of spoilage organisms taking foot.
Your fermentation also suffers an increased chance of stalling out early without nutrients
Further, without the nutrients the yeast can become stressed and produce off flavors and sulfur like smells.
A "show" is a mead brewed without any extra flavorings or nutrients, people do it all the time, but they're extremely tricky.
A traditional is done with nutrients but no other things mixed in (honey & water only)
It is often said that the only reason for doing a show mead is to "show that you can" This is because it takes a crazy good pallet on the range of Chef Ramsey to tell the difference. Even then it's debated frequently if he could tell the difference between a trad and a show mead.
If you want a ferment to go nice and smooth, nutrients and HIGHLY recommended.
