How does the secondary fermintation help & how do you go about it?
Hi Cos
There's a few answers to that. I'm a beer brewer, so i use beer brewing terms!
Firstly be very wary of the term "Secondary" lots of people have different takes on this and it's frequently misused and misunderstood, but the way I see it there's Primary and secondary fermentation and there are Primary and secondary fermentors/fermentation vessels (FV) and they are different things!
Primary fermentation is the conversion of sugar into alcohol, in this case this will be happening right up until it's been in the bottle and the yeast has used up all the sugar.
Secondary fermentation is giving the yeast time to clean up and flocculate (drop out) before serving (better to call it conditioning really). In this case this will happen mainly in the bottle once the sugars used up (The beer term would be bottle conditioning).
The primary Fermentor was the bucket with the elderflower and lemons, racking to the secondary fermentor was moving it to the demijohn.
When I said "I'm going to add another 1.6kg of sugar going to secondary" I was talking about the secondary fermentor. The fact I added sugar at this stage might be misleading. There are good reasons for doing it this in certain circumstances like brewing very high gravity beer with sugar, or adding fruit to beer, or yeast health. But in this case I did it for a couple of reasons. Firstly because I was splitting the batch between 4 demijohns I wanted to kick of another strong fermentation and healthy yeast growth so there was a good amount of yeast cells in each fv. But mainly I'm afraid it's because I didn't have enough sugar on the day, and it wouldn’t hurt to add it to the secondary so that's what I did (Sorry).
Hope this helps
