2.3. Maturation and storage of wines
In February 2006, each type of wine was submitted to two
different maturation practices, using two types of containers:
400-L stainless steel tanks (A) and 225-L middle-toasted American
oak barrels (R); barrels were purchased from Magreñán (Logroño,
Spain). For each wine, two stainless steel tanks and two oak barrels
were used; wines were maintained in the maturation containers
for two or three months. Thus, eight different wines were obtained
after the maturation process. After maturation, wines were treated
with gelatine (2 g/100 L) and sodium bentonite (30 g/100 L),
filtered through diatomaceous earth, stabilised at –4 C for 10 days,
and finally filtered through a filter press. Then wines were bottled
in 750-mL glass bottles, using premium cork stoppers. For each
wine, two different sets of bottles were obtained. A set of bottles
was maintained in a chamber at 14 C (set C). The other set
remained at room temperature, between 10 and 30 C (set V).
Wines were analysed three and nine months after bottling. In summary,
32 different wines were obtained, combining five different
technological factors:
