Is there any way to harvest and save the MLB from your grape fermentation? Seems like a bit of a waste to buy another packet (at $8-10/g) for every wine over and over. How much MLB is left in wine after the post-fermentation sulphiting and aging? Is there anyway to inoculate oak spirals or staves with the bacteria, and save them somehow, to infect the next batch? I've heard of barrels that are inoculated (infested? LOL) with the bacteria and initiate MLF in any wine they come in contact with.
