After spending a great deal online reading about fermentation methods and techniques, I stumbled upon a style the produces an effect that is right up my alley: delestage
The article about it on WineMaker Magazine’s website is a great read.
In summary, you basically drain the juice from the bottom of your fermentation vessel, filtering the seeds and stems (which adds the astringent, sharp taste and mouthfeel). With the juice separate from the cap, you pour the filtered juice over the top the cap about twice daily. The result is a softer, smoother, more fruit forward wine.
Though labor-intensive, I thought it’d be fun to try out. I’m intending to acquire a small batch of (frozen must) Merlot from Brehm Vineyards and will use this technique during primary fermentation.
I needed to convert one of my plastic tubs to do so which wasn’t difficult at all. I purchased a small spigot with a 1″ diameter spout and drilled the hole using a standard 1″ boring drill head. To make a tight seal, I wrapped the spigot threads with standard plumbers tape and used a washer on both sides of the tank before screwing the spigot in place.
UPDATE:
This failed quickly. I started a batch of Merlot and wanted to try this technique but the grapes and seeds immediately clogged the spigot. After further inspection, the hole that the juice drips from would probably get clogged from any seeds that would make it by if the grapes were held at bay.
I wonder if this only works when in full-on fermentation and the cap rises? I’ll have to look into which kind of spigot would work best too. Great idea, but poorly executed. Live and learn!
