All malolactic bacteria sold by Scott Laboratories requires an expedited shipping method packed with ice. Please refrigerate or freeze all cultures immediately after receipt to ensure optimal viability of the bacteria when used.

These bacteria were produced according to a proprietary process that is different from competitive direct inoculation products. Thus, provided that any warming period is short term and moderate (e.g. 48 hours at 86°F/30°C), viability will be excellent.
