Here's that C/P from gardenweb on FPEs via Russian Kvas you asked for, Seamaiden,
-----------------copy/paste job--------------------copy/paste----------------------------copy/paste------------------------------------
Main idea is to use non-alcohol fermentation in the gardening based on the fermenting cereals� grains. There are many ways of fermenting cereals to make beverages. But trying to be as simple as possible we came to this simple formula:
6 tbsp rye flour + 2 tbsp molasses + 1 gallon water, sit 3 days.
(author - Nandina)
This stuff is called on Russian kvas, I�ll use this term for designation.
Chemical composition: lactic acid, acetic acid (vinegar), enzymes, vitamins, antioxidants.
Microbial population: lactic acid bacteria, yeasts.
Physical properties: acidic, white color if made without molasses.
Way to keep: closed under the lid or covered by plastic film if kept in an open barrel.
Behavior: tend to be more acidic with time.

Kvas may be used in the garden directly for watering and sprinkling plants diluted with water in ratio 1:0, 1:1, 1:10, 1:100, 1:1000. Better to use more diluted and more often. But pure kvas may be applied too, without hurting.
Kvas may be used for fermenting everything else in the garden: weeds, fruits, peels, etc to make fermented plant extract (FPE). Just put them in the kvas and wait some days. Herbs increase their healing and antioxidant properties tens times after fermentation with kvas.
As a tool for insects, ferment garlic or/and pepper and/or any herbs used as repellent. Use in dilution 1:100 � 1:1000 for sprinkling plants every other week.
There are more advanced recipes of making kvas based on using malt, making sourdough bread in oven, etc. (in this case microbial population will have also photosynthetic bacteria). But this recipe is simple and good for beginners.
With the given information everybody can try it in the garden.

I'm starting my first batch as we speak, so that I can use it on my new pepper bed. I'm going to sell some Aji Dulce's this summer and was already planning on a medicinal herb garden so i decided to do a 4x8 raised bed instead of a 4x4. SFG that sucker with herbs
and Peppers. So after I'm done filling and amending my SFG bed I'm going to water it in with a 1:100 dilution of kvas to kickstart the cooking process. I'm also going to be using a 1:10 dilution on my compost pile from the winter to get it going strong, and I will also be fermenting wild garlic and hot pepper (perhaps, along with horsetail and stinging nettle) as an all purpose insect preventative per the recommendations above, though most likely that will be the next batch.
be easy,
