Why is my beet kvass slimy?

Beets, salt, water, a jar on the counter for five days. The colour is a beautiful deep ruby and the smell is earthy and sour and fine, but when I pour it, it comes out thick and stringy. It trails off the spoon.

I grated the beets this time instead of cubing them, and the kitchen has been warm. No fuzz, nothing coloured growing on top. Is this recoverable or do I start again?

    Two other prevention items. Enough salt, following a recipe you trust rather than eyeballing it, because thin brine makes this more likely. And a weight to keep the beets properly under the liquid, since anything sitting above the brine is where trouble starts.

    On your actual batch: give it a gentle stir, move it somewhere cooler and taste it in two days. Ropiness does sometimes break down. If it is still trailing off the spoon, it is a fresh batch.

    Grating is most of it and the warmth is the rest. Ropiness comes from bacteria producing thick stringy compounds while they work through sugars, and grated beet releases far more sugar far faster than cubes do, so you handed them a lot to work with in a warm room.

    Some recipes warn about grated beet for exactly this reason, and for pushing the alcohol and off-flavours up too. Cube them next time, it genuinely changes the batch.

      Is five days also too long, or is that normal for kvass?
