pardon my ignorance, very first batch and keep seeing the word 'racking' and assumed it meant 'bottling' .the instructions did not give any specifiics on racking - so, without actually knowing what racking means I can only say, that we syphoned from the carboy 7 days after adding the fining agent
Yea, this terms can be a challenge some times, especially when one assumes the other person understands. We have all been where you are, so don't sweat it.
Racking is the process of siphoning the wine off the sediment or lees from one container to another, clean container.
I don't know your particular instructions, but for me, 7 days is pretty quick for bottling after fining.
One thing is for sure, if it is cloudy in the bottle, it will forever remain cloudy. So, to get rid of the cloudiness, you will likely have to open each bottle and pour it back into a carboy.
The bitterness/tartness can be explained by one or both of the following:
1) New red wine, like merlot, is always going to be tart until it has aged for at least several months and maybe longer.
2) The wine was not fully degassed. This is a common problem for new wine makers. Sometimes it is hard to know when the wine is fully degassed.
I'll assume for a moment that you still need to degas. Open a bottle and listen if you get a little pop as the cork comes out. By little pop I mean a pop greater than you typically get when you open a bottle of commercial wine.
The pop may indicate you have not fully degassed.
Next, put your finger over the top of the bottle and shake the bottle well. Remove your finger. Did you get a sudden release of gas coming out and/or did you get lots of foaming and fizzing inside the bottle after shaking? Either of these indicates you need more degassing.
If you want further proof of excess CO2, pour the wine in a pitcher or wine decanter. Immediately taste it and remember the level of tartness. Leave it for about 30 minutes and taste it again. Has the tartness subsided some or a lot? Some or a lot also indicates too much CO2.
The presents of CO2 in the wine at fining can negatively affect the fining, so if you have CO2, that is likely why your wine did not clear.
If CO2 is the problem, after pouring bottles back into carboy, degas again. As long as tiny bubbles keep coming up the sides of the carboy, you need to continue degassing. When you think you are done, fill a bottle halfway with wine and do the above shake test. It should not fizz or pop a lot when you remove your finger. repeat degas if necessary.
For cloudiness - You can go buy some superKlear and following its instruction to fine again. Or, you can let the wine set in the carboy, under air lock for about 30 to 60 days to allow sediment to drop out.
After sediment drops out, rack to a clean carboy and bottle. DO NOT BOTTLE UNTIL THE WINE IS PERFECTLY CLEAR.
I know this degassing thing sounds complicated. Believe me, we all went through this. Ater you get the hang of it, it will be a piece of cake from then on.
Good Luck!!!
