Description

Lactoenes 450 PreAc Batteries with Energizer

LACTOENOS 450 PreAc®

Œnococcus œni strain for a quick MLF start, combined with the exlcusive 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 Totale (mg/L): Up to 60
  • Temperatura: From 16°C (60.8 F)

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

Chemical and microbiological analysis

  • Humidity (%) < 8
  • Bacteria counted on each Petri dish (CFU/g) > 10¹¹
  • Mould (CFU/g) < 10³
  • Yeast (CFU/g) < 10³
  • Acetic bacteria (CFU/g) < 10⁴
  • Salmonella (/25g) None
  • Staphylococcus (/g) None
  • Coliforms (CFU/g) < 10²
  • E. coli (/g) None
  • Lead (ppm) < 2
  • Mercury (ppm) < 1
  • Arsenic (ppm) < 3
  • Cadmium (ppm) < 1

Protocol for use

  • Inoculate as soon as possible. There are several inoculation methods:
         - Early co-inoculation (bacteria inoculation 24 – 48h after the alcoholic fermentation start), technique more and
           developed that we advise for its many advantages like the optimisation of bacteria efficiency.
         - 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 /68°F 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 /68°F in late co-inoculation or sequential inoculation. Add to the tank.
  • Maintain the tank temperature throughout the MLF (at about 20°C /68°F).
  • In hard conditions (sluggish AF, poor medium or high alcoholic degree) and for a quicker MLF kinetic, 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 /-0.4°F or +4°C/32°F) in its unopened original packaging.
  • Optimal date of use:
         30 months at -18°C /-0.4°F.
         18 months at +4°C/32°F.
  • Do not use opened packaging.

Packaging

  • Dose for 50 hL
