Malolactic bacteria Lactoenos 450 PreAc with Energizer (50 hL) Laffort

Malolactic bacteria Lactoenos 450 PreAc® with Energizer

LACTOENOS 450 PreAc®

Œnococcus œni strain for a quick MLF start, combined with the exclusive production process: PreAc®.

Qualified for the elaboration of products for direct human consumption in the field of the regulated use in oenology. In accordance with the current EU regulation n° 2019/934.

Specifications and oenological applications

• Strain with a high resistance to ethanol.
• One of the strains with the highest malolactic activity on the market in optimal conditions.
• Low production of diacetyl and ethyl lactate.
• Low volatile acidity (VA) production.
• No biogenic amine production.
• The blend of effectiveness and cost makes LACTOENOS 450 PreAc® the ideal preparation for the control and reliability of malolactic fermentation in white and red wines of any style.

Survival and activity spectrum of the LACTOENOS 450 PreAc® bacteria:

• TAV (% vol): Up to 17
• pH: From 3.3
• SO₂ Total (mg/L): Up to 60
• Temperature: From 16°C

LACTOENOS 450 PreAc® allows a rapid onset of MLF. Implementation is simple (in 30 minutes only for early co-inoculation and in 12 hours for late co-inoculation or post AF inoculation).

LACTOENOS 450 PreAc® is aromatically neutral and permits to preserve the fruity character of the wine.

Physical characteristics

• Aspect: Powder
• Colour: Clear beige

Protocol for use

• Inoculate as soon as possible. Inoculation methods: - Early co-inoculation (bacteria inoculation 24–48h after the alcoholic fermentation start). - Late co-inoculation (inoculation at 1020–1010 density). - Sequential inoculation.
• Do not use opened bags.
• Use a container inert and clean. Mix 1 L of mineral water and 1 L of wine at 20°C for 50 hL dose. Dilute ENERGIZER®, and then add the LACTOENOS 450 PreAc® dose. Homogenise and let it rest for 30 minutes in early co-inoculation, 12h at 20°C in late co-inoculation or sequential inoculation. Add to the tank.
• Maintain the tank temperature throughout the MLF (at about 20°C).
• In hard conditions, add 20–40 g/hL of MALOBOOST®.
• Respect the volume of wine indicated on the bacteria dose (50 hL).

Storage recommendation

• On reception, keep refrigerated (-18°C or +4°C) in its unopened original packaging.
• Optimal date of use: 30 months at -18°C; 18 months at +4°C.
• Do not use opened packaging.

Packaging

• Dose for 50 hL
