This is the first year I am planning on malolactic fermentation for my
reds if acidity is right. Two questions: 1. Given that Zin tends to get high in alcohol, I am considering adding MLF during primary fermentation. This make sense? 2. Tempeture wise, I have two choices - a wine room at 56 deg or in the house which probably averages mid 70s. Looks like the house is the better temp for this but would like to get it into the wine room as soon as possible. Any experience if adding MLF bacteria during or after primary fermentation hastens MLF? thx for any insight, dan |

It's useful to take advantage of the temperature spike during fermentation to get the ML going. If you're going to do this, let the fermentation get started for a day or so and then add the ML culture. BTW, you should not add any sulfite at crush or the ML may not start until much later. Also, don't do this using a Bayanus strain of yeast such as the ever-popular EC1118 (Prise de Mousse). Bayanus and ML bacteria compete for the same nutrients IIRC. The above are recommendations from The Wine Lab. I've followed their advice for many years with no problem. > 2.

That won't kill the yeast, and it makes for good color extraction. I once had a Pinot Noir peak at over 100ºF without sticking. It went dry virtually overnight! (That was in 1983, and it was really hot that year.) Anyway, the time for the cold room is after the wine finishes ML. That's also when you should first add sulfite. Tom S |
