I have been fermenting Citrus wines for a while now. The acidity of the Wine Must makes Wine Yeast choices very limited. Lalvin EC-1118 & Red Star Coates de Blanc are my 2 most reliable but still take 2-4 days for fermentation to begin. A lot of Wine Makers do not bother with using the Yeast Starter method although the Yeast manufacturers recommend it. I use a digital temperature probe to monitor starter water temperature. Using distilled water I put 3/4 cup in a 2 cup measuring cup microwave safe. After heating the water to over 110 degrees I monitor the water temp closely till it falls to 110 degrees. At this point I add 1/2Tsp Scott Laboratories Go-Ferm GO-FERM™ | Scott Laboratories stirring it well. Stirring cools the water. Once the water reaches 104 degrees I add 1Tsp sugar and my Yeast. I just sprinkle the Yeast on top allowing it to wet out and sink on its own. Once the yeast is foaming well, about 20 minutes I ladle 1 scoop of Wine Must into the Yeast Starter every 5 minutes for 3 scoops of the ladle to acclimate the Yeast to the environment I am adding them to.
To provide the Must with the proper nutrients for successful Yeast start I add a couple of things to the Wine Must itself. Here I added 2 Tsp Yeast Nutrient (basically a yeast fertilizer) and a special additive Fermoplus Integrateur Fermoplus(R) integrateur for brewing at the best online price - COMPLEX for brewing | AEB US to finish out my supplement program. Bon Temp's Honey just provides some kind of added benefit because not even 12 hours after pitching the Yeast they are already at work.
In a Wine Must the cloudiness seen here is the Yeast already hard at work. It is just remarkable.
