Wine Filtration - Depth Filters

Read previous Wine Filtration article - To Filter or Not?

Winemakers continue to learn how to best apply filtration. As research continues and technology improves, the options available have grown with the industry over the past several decades. Depth filtration, also referred to as dead-end filtration, has been utilized by winemakers for centuries. During the process of depth filtration, wine is directed in a perpendicular flow towards the filter medium (directly into it, thus the term 'dead-end'). The retentate (particles removed) is captured inside or against the filter medium, while the clean wine passes through. The retentate gradually builds up over time, pressure increases, flow rate decreases, and the filter eventually becomes plugged. At this stage, filtration must be stopped and the filter setup cleaned before further filtration can be done. The most common forms of depth filters are pressure-leaf, plate & frame, lenticular, and cartridge.

Wine Filtration - To Filter or Not?

Another winemaking question that arrives at the answer, "well it depends".

I've never seen a wine marketing campaign discussing anything about a filtration program except for the absence of one. For quite some time, the debate over whether or not to filter a wine has intrigued wine professionals and consumers alike.

So what's the point, who's doing it, and does it help or hurt?

Fratelli Perata 203 Cabernet Sauvignon Riserva

The Perata brothers joined the budding wine region of Paso Robles in 1977 when they purchased a 40-acre plot just west of Highway 101. The Fratelli Perata winery was bonded in 1987, just a few years after Paso Robles was granted appellation status. Ever since, the family have been producing single vineyard wines of character on site.

Fratelli Perata presses all their Cabernet Sauvignon directly into new French oak barrels after fermentation. After two years of maturation, the family sets aside the best for their riserva. Its complexity and structure are aimed with aging in mind.

Malayan Water Monitor

During a recent visit to the Singapore Botanical Gardens, Kristin and I watched as a 1.5-meter lizard fluidly swimming across a lake. I recognized it immediately as a monitor lizard, but never knew they could swim so well.
