Zinfandel grapes -> wine! A new member's introduction via a 75L of red deliciousness.

I conducted a test last year, using K&C on two different wines. The result was that the use of K&C reduced nose and introduced a slight bitterness.

I'll use bentonite on whites and fruit wines, but not on reds, as it strips color. Generally I use a lower dose than indicated.

Filtering? I did that many moons ago, but decided it wasn't worth it. In recent years I barrel age reds for a year, then bottle.

K&C results are surprising, was the wine aged well before sampling?

I barrel aged two reds for 12 months, bottling most of each, and treating 19 liters of each with K&C. That was Nov/Dec 2022.

Taste testing was conducted June, July, and August of last year (2023), by numerous people. My results are documented here:

This is literal gold! Thx for the work on this.

K&C is WIDELY used in industry and is likely the method employed for most wines that are <$30 / bottle. You do pay for top quality, so I guess I'm not too surprised by your findings--old school is still best!
