The role of racking in wine production
- Do not disturb the dregs
- No pumps
- Use suction to push the wine delicately from one barrel to another
- Real decanting begins when the greater part of the wine has been taken out
- Requires coordination of two cellar workers
- One worker gently tilts the barrel
- Drawer checks the consistency of the flowing wine with the help of a candle and as soon as the wine becomes hazy, the operation is halted.
Phenolics such as anthocyanins and tannins are responsible for the color and mouthfeel (astringency) of red wine... Tannins themselves are polymers, large molecules composed of smaller subunits bonded together in a specific way. After tannin polymers are extracted from the skins and seeds of grapes, acid hydrolysis in the grape juice and wine breaks these large polymers into smaller polymers and monomers ... when oxygen is introduced to the wine, it reacts with metals to start a chain reaction that leads to the activation of monomers, making them more likely to react with other monomers to reassemble tannin monomers into polymers. Each time two monomers (or a growing chain and a monomer) bond, they become even more likely to bond again, leading to elongation of the tannin polymer. Put simply, activation by oxygen can begin a cascade that results in faster formations of phenolic polymers. These chains continue to grow, adding more phenolic subunits, until they bond with an anthocyanin. When an anthocyanin is added to the chain, it is not likely to bond with anything else, effectively capping the chain.
These chain reaction of tannin molecules have important effects for the color and astringency of the wine. The perceived mouthfeel of tannins is, in part, related to the length of the phenolic chains. Longer chains have more reactive sites for interaction with salivary proteins, thus the higher the degree of polymerization, the more astringent tannins seem. Micro-oxygenation ... is thought to bind anthocyanins to growing chains before they are lost to precipitation, enzymatic attack, or binding to lees, resulting in better color retention and shorter tannin polymers ... Polymeric pigments (tannin polymers capped with anthocyanins) are less susceptible to oxidation and browning than monomeric anthocyanins so micro-oxidation also aids in color stability by preserving anthocyanins in solution in their colored form.

Co-Inoculation as a risk-mitigation strategy in malolactic fermentation
- Better control over the winemaking process in terms of time management
- Shorter AF-MLF cycle
- Bacteria are introduced into a low-ethanol, high-nutrient environment with the lowest pH the wine will probably experience
- Bacterial activity is suppressed during active fermentation but cells acclimatize their membranes to the rising alcohol during this time
- Microbiological activity of both the yeasts and the bacteria work to limit development of contaminating organisms
- As yeasts begin to die at the end of AF, they release nutrients into the wine just as malic bacterial production begins to transition from lag to log phase
- When MLF occurs under the reductive conditions of AF, lower levels of diacetyl and higher levels of fruity esters manifest in the wine.

For me the best wine of the flight, perfume on the nose, rose petals and potpourri, rocky tannins with cherries — Brian
Luxardo cherries, balanced, tobacco notes and graphite – showing Pauillac almost, one of the better 2000 wines I have had this year — Brian
Still a great wine but with a shorter finish than the Leoville. A very balanced wine with less fruit than the Leoville — Brian
It’s a 1996! Exactly what I thought it would be – excellent, thyme and sage notes blended with great cherry fruit and pencil lead. Tannin and acid matching and balanced. — Brian
Very short wine, still a very clean wine but fruit was less pronounced. Easy to drink but not complex — Brian
All tertiary flavors at this point. Lots of tannin and acid. Very different from the other 1983s I have had this year — Brian
Wow, what a wine for the age. Fantastic start and has a cola taste about 5 seconds in and has length, light tannin, and acid – my #1 — Brian
