I will rack and do a next trial. Was expecting to add TA. I thought the closer to 100+ ppm the better chance it have a sulfite taste. Would love for the PH to come down naturally. I have never had a wine increase from 3.6 to 4.0 in MLF. Will also add some oak staves. Usually bottle in a...

TA was 7.0 post MLF

I have just finished MLF last week with 95 gallons of Petit Sirah. I used Chris Hansen Viniflora Oenos ML bacteria as always. I have 80 gallons in a Flex tank and the rest in 2 carboys. Determined MLF finish through Chromatology testing. I measured Ph and it has risen from 3.63 pre Alcoholic...

Petit Sirah pressed will be ready for MF later this week. Jeff

Racked the Verdicchio off the gross leas last night. 60 gallon tank was 39 PPM SO2 42 gallon tank was 56 PPM SO2. So far a success. Used pectin enzyme to clear the wine. That will take some time. Tonight we press 49 lugs of Petit Sirah the fermentation went fast 5 days to -1 Brix. Will post...

TA should drop during fermentation and malolactic fermentation. The must is very tasty and sweet and no hint of high acid. Just pitched the yeast in 7 primary fermenters we also need off 24 gallons for Rose prefermentation. We will see how things are in the morning. Jeff

The White is still fermenting have both tank small amounts of nutrients 1 gram per 5 gal. over the last two days. The 7 Petit Sirah primary fermenters average Ph was 4.05 average now after Tartaric acid addition is 3.63. Should be ready to start fermentation today. Jeff

Fermentation is continuing on the Verdicchio. Stalled at 10 Brix in the large tank yesterday so I fed 1 gram per 5 gal. of Fermaid O last night and this morning it was at 6.5. Also brought home 49 lugs of Paso Robles Petit Syrah yesterday. I have 7 fermentation. Each Barrel has 21 gallons of...

Both tanks are actively fermenting. Added yeast nutrient. It has almost dropped 10 Brix. When it does it will be done 1/3 and will add another dose of fermaid o. The sulfite smell is gone. The temp was moving up to 76 so I added 2 gallon jugs of frozen water to each tank. Should control...

Tuesday Went to check the tanks this morning and both tanks were fermenting. The 42 gallon tank started up on its own so I added yeast nutrient and the 60 gallon of tank got a new batch of hydrated EC 1118 yeast yesterday. The 42 gallon tank has a sulfide smell will continue stir it. Any...

Stirred it twice this afternoon with a drill and stirrer. Lots of agitation. Will splash rack tonight and measure SO2 level in the morning. Thanks Jeff

Any suggestion on how long I should wait between splash rackings. Yesterday I did two about 4 hours apart. I rack them completely into another tank and then return them to the flex tanks. Then tested SO2 this morning before racking. Thanks Jeff

Not very significant but it did drop a little.

Sulfite levels 60 tank was 190 now 172 42 tank was 181 now 171 Splash racking now. Will do again in a few hours.

I am in agreement. Will keep you posted about SO2 levels etc. Jeff

I am also not sure when I should hydrate a new batch of yeast. Have used QA23 yesterday and will change to EC1118 which has a tolerance to higher SO2. I just checked the tanks and the 42 gallon has some bubbles on the surface. Will check again in an hour and if it has increased will add...

Tested the sulfite level today before splash racking 190 in the 60 gallon tank and 181 in the 42 gallon tank. I plan to splash rack again this afternoon. I greatly appreciate all the responses. I tasted the juice as I have not had fermentation begin yet and it is typical white juice sweet and...
