There is some element of confusion about "primary" and "secondary"
fermentation Having been making so called "country wines" for over 30 years and more recently since kit wine makers made huge improvements with the end product of their kits, I have also made quite a lot of top line Kit wines. Secondary fermentation always meant, to me, one of two things. 1. That fermentation that takes place in the bottle of sparkling wines to produce the "Fizz" and also the similar process that takes place in "Bottled conditioned" beers. 2. Also in wine making the Malolactic fermentation was always referred to as a "secondary fermentation. Both these types were true secondary fermentation in that the fermentation was "RESTARTED" at some time after the primary fermentation had finished. In the case of my sparkling wines it was not less than 6 months after the primary had finished! BUT the wine kit manufacturers "stole" the term as their kits improved and these days "Secondary Fermentation" frequently refers to the continuation of the Primary fermentation after a first racking off the lees. It really is just a continuation of the primary fermentation! So you don't have to worry about the "secondary" cheating your must of its necessary nutrients and going too fast. As far as I can tell from your ost --- all is OK In fact, after racking into the new "glass jug" and as the SG creeps lower, the fermentation slows down very quickly ( yes I know that sounds potty!). As the sugars decrease and the alcohol increases so the yeast has less sugar to convert and is also finding that living conditions are becoming more difficult due to the increase level of alcohol and the yeasts give up the ghost and go to the yeast place in the sky! -- Trevor A Panther In South Yorkshire, England Remove "PSANTISPAM" from my address line to reply.

Specific Gravity Thingie | Winemaking | |||
specific gravity to alcohol - hydrometer readings scare me. | Winemaking | |||
Please help me to convert from plato to specific gravity. | Winemaking | |||
