No. The beneficiary of the spouse and the child coverage will be the member. If the member were to die before payment could be made, the proceeds of a spouse or child claim would be paid to the member's beneficiary, as designated by the member on the form SGLV 8286.
Indeed, the volume varies from one region to another because of tradition and long local history of winemaking. In Bordeaux, a barrique contains 225 liters (60 US gallons). In Burgundy, it is 228 liters and is called a piece while in the Loire Valley it is 232 liters. Tonneau is another word used for barrel. In Bordeaux a tonneau contains 900 liters and means 4 barriques.
That is also when I would recommend you put your wine in the barrel. That being said, the direct answer to your question is: add the bentonite first; let the wine clear; then go to the oak wine barrel. One thing you have do have to be concerned when aging a wine in a barrel is how long to keep the wine in the barrel. A vast majority of the wineries will barrel-age anywhere from 18 to 30 months. This is perfectly reasonable if using 50 gallons oak barrels, but when using smaller oak barrels, the length of time needs to be much less.
