…and heart, circulatory and lymphatic systems and evidently to my hands! We’ve been talking about phenols, and polyphenols. Let’s continue with another branch of the phenolic group: anthocyanins (and their sugarless counterparts the anthocyanidins). Anthocyanins are highly pigmented, water-soluble phenols. They contribute the red, purple and blue colors in fruits and vegetables. The colors that […]
Soon the vines will start to wake up. They will begin to weep as the sap rises from the roots where it was stored over winter. This years buds will start to get fuzzy as they get ready to swell into larger buds and eventually break open and show off their bright green leaves!
We’re going to wrap up this month of barrel talk with a little bit about these compounds and what contributions a barrel can give to a red wine. . First of all…what is a phenolic compound? A phenolic compound by definition is an aromatic organic compound that has a phenol ring in its structure. There […]
We do this periodically to prevent the wine from spoiling. A barrel is not an airtight container such as a stainless-steel drum. A barrel will allow evaporation of wine through the wood itself and the tiny spaces between boards of the staves and the heads. This evaporative process drives the phenomenon called microoxygenation (or microx) […]
Here’s a bit of information that we found from one source Let’s start with the smallest called a Firkin. This little guy holds a mere 41L (11 gallons) and is traditionally used for dispensing cask ale. A few sizes up is where the wine barrel called a Barrique or a Burgundy comes in, American oak […]
Storing wine in oak barrels offers several contributions such as: micro oxygenation, malolactic fermentation and addition of flavors. A few things that affect flavors that are contributed to wine are: The type of oak used (mainly French or American oak); the time that the wine is stored in the barrel; and the toast inside of […]
