Ossia yeast.

[CheerfulHeart]

I am an amateur home winemaker and heard about this organic yeast. I would be grateful for any input that might be offered regarding special nutritional needs or things I would need to watch for. Would Ossia be a good all-purpose replacement for EC-1118? Many thanks in advance.

Do you have the sense that other winemaking yeasts are NOT organic?

It depends on your goal. If you want to produce an organic wine, using an organic yeast like Ossia is a way to go as many yeasts such as EC-1118 are not organic. EC-1118 does come in an organic version, as well, called EC-1118 Organic. Like organics in general, the organic form of EC-1118 is more expensive. If your concern is reducing the risk of H2S, EC-1118 is a low H2S producer (not zero like Ossia) and has other benefits.

Ossia requires nitrogen supplementation during early fermentation. Stay above 59F, preferably between 64F and 90F.

What makes a yeast not organic? Is just that it is not listed as fully organic?

Some yeasts are available in an organic and non-organic form. The very popular EC-1118 is an example.
Organic yeast is produced in using totally organic nutrient solutions. In addition, all ingredients in the yeast production process are non-GMO. Many governments including the EU, the USA, and Australia have requirements for a yeast to be labeled organic.
