Default malolactic fermentation

This is a subject that has come up time from time in this group. I
think i have read up on this enough to know what it is, and how to
work with it.

My bigger question is this. How many of you out there that re trying
to make a quality dry red wine actually induce a Malolactic
fermentation cycle.

Here is why I ask. I plan on getting 75 gallons of fresh crushed
California Cabernet Sauvignon grapes this fall and want to take my
wine making to the next level on both quality and quantity.

I am reading furiously and meeting folks who make a lot more wine than
I do. Twice now, I have personally met winemakers that have been
making wine for 50+ years and ask them a technical question about
freee SO2 or PH levels, or Acid blends, and both times i get the same
general response:
An exhasperated "Wayne, I just smash the grapes. You are waaay over
thinking it."

Not those words exactly, but close.

So my question is this. How many folks really do go out and buy the
malolactic cultures like leuconostoc oenos and induce MLF? Is this
common?

Default malolactic fermentation

I would say 'yes - it is very common'. One of the main reasons for
inducing MLF is to ensure that the subsequently bottled red wines don't
spontaneously go into MLF while in the bottle. Another is to change the
acid profile, thereby the taste profile (malic acid being a crisper,
more tart taste, better suited to crisp, lively white wines).

Possibly you are overthinking things. Then again, possibly those two
winemakers are underthinking things.

Do you use chromotography to monitor your MLF?

Paper chromatography, yes. But it is a once a year sort of deal. I test
my reds to ensure that mlf is complete before I consider bottling. In
my cellar, mlf usually gets going well soon after primary, but then
stalls during the winter (temps in the cellar drop to anywhere between
56 and 59). Kicks in again in the spring. But I always test later in
the year to be sure - before bottling.

I hate to keep bending your ear, but I will until you tell me to
stop.

When, relative to primary fermentation, do you innoculate for MLF?
at start?
-or-
50% through?
75% through?
90% through?

Default malolactic fermentation

This is the question that will likely generate some debate.

I used to innoculate soon after primary was underway, on the
presumption that the ml bacteria would get a better start while the
alcohol was lower. Then, some fellow winemakers who profess to knowing
far more than I ever could suggested that I was risking some
undesirable volatile acidity by doing so (I am still uncertain of the
biologic basis for this). So I now innoculate late in primary - soon
before press. Not sure it really makes a difference, but done this two
years in a row now with no problems, so planning on continuing thus
until better information convinces me otherwise.

How about you? When do you innoculate with ml bacteria?

When do I Inooculate?
Let me quote a wise man:
"So I now innoculate late in primary - soon before press."



I've never done it. But read enough to know that I think i should be.
BTW, everything I know about MLF I am reading in Philip Jackisch's
"Modern Winemaking" book. In it, he states:
"The ML culture can be added to red wines at the time of pressing,
ordinarily at about 5 deg Brix. and should be 1-5 of the volume of the
juice."
That is from Chapter 5 "Microorganisms and Fermentation" Page 79.

So, sounds like the old timers were dead on.

Only thing I don;t understand there - "shold be 1-5 of the volume of
the juice" ?? what does that mean?

I buy the small dried bacteria packets. I pitch them directly into the
fermenting must. Some folks start it in water, much as we do yeast (for
my reds, i figure it has a year or two to do it's thing, so I'm not too
worried about making it start right away - but it always does!).

Sorry - potential Typo:

Should have read "1-5% of the total volume"

Very sorry.

Nice read, Thanks Steve.

In reading from the www.morewine.com web site about ML cultures I
read this:

"Note: Malolactic bacteria added during the ferment will compete with
the yeast for nutrients and are atagonistic to yeast, sometimes
causing problems resulting in stuck or stalled fermentations. The best
time to add an ML culture is after racking off the gross lees.."


With so many variables and so many opinions involved in winemaking, I
am beginning to think it takes a pointy hat with moons and stars on it
to make good wine.

Ok, just to muddy the waters a bit, I rarely induce MLF because most
of my grapes are low acid to begin with. Proper sulfite levels can be
used to prevent spontaneous MLF. It really depends on your grapes,
if they are on the underripe side they will likely be high in TA,
lower in pH and great candidates for MLF. Mine are usually the
opposite. If you do this, I prefer later in the ferment too; the TA/
pH balance is closer to stable and you know where they ended up; the
sulfite level has dropped to the point MLF can take off too.

As to cultures, once ML bacteria are in your winery space it just
happens on it's own. I know that seems a little hard to believe, but
I keep things relatively clean and get spontaneous MLF often if my
sulfite levels dip. If the wine is a little high on TA I let it have
at it. I'm either bringing it in on the must or it's in my winery. I
never saw it before I bought a culture for some Chancellor so suspect
the latter.

Joe ,

I don't add MLF culture and I can smell the MLF starting about half
way thru the primary anyway. I would think adding MLF culture just
before pressing would be wasting alot if a non bayanus strain of yeast
that promotes MLF was used in the primary. I would use prisse de
mousse on a red if I wanted to wait until after the primary to start
MLF and also add MLF nutrients with the culture. JMO.

You either have a good nose, or MLF has a distinct odor. \

Nice read, Thanks Steve.


In reading from thewww.morewine.comwebsiteabout ML cultures I
read this:


"Note: Malolactic bacteria added during the ferment will compete with
the yeast for nutrients and are atagonistic to yeast, sometimes
causing problems resulting in stuck or stalled fermentations. The best
time to add an ML culture is after racking off the gross lees.."


With so many variables and so many opinions involved in winemaking, I
am beginning to think it takes a pointy hat with moons and stars on it
to make good wine.


Ok, just to muddy the waters a bit, I rarely induce MLF because most
of my grapes are low acid to begin with. Proper sulfite levels can be
used to prevent spontaneous MLF. It really depends on your grapes,
if they are on the underripe side they will likely be high in TA,
lower in pH and great candidates for MLF. Mine are usually the
opposite. If you do this, I prefer later in the ferment too; the TA/
pH balance is closer to stable and you know where they ended up; the
sulfite level has dropped to the point MLF can take off too.


As to cultures, once ML bacteria are in your winery space it just
happens on it's own. I know that seems a little hard to believe, but
I keep things relatively clean and get spontaneous MLF often if my
sulfite levels dip. If the wine is a little high on TA I let it have
at it. I'm either bringing it in on the must or it's in my winery. I
never saw it before I bought a culture for some Chancellor so suspect
the latter.

You either have a good nose, or MLF has a distinct odor. \

Can you describe the odor?

I think wines going through MLF often have a slight "sour cabbage" smell.
