It was already showing 1.050 on my hydrometer so no sugar added. its upto temp using belts and seams to be stuck?????????? there,s a creamy fur type showing off the pips floating on top??????????????? we got sediment at bottom of course off the grapes will this stop it hope u can help x em

12 gallons is a big volume, it'll take the yeast a while to fill it before actual fermentation starts properly. The fur may be the start of the yeast head forming. How much yeast, did you make a starter?
