Anche Palmer in brewing classic style dice che il travaso intermedio serve solo per birre a lunga maturazione

Dice

In general, we recommend a single-vessel fermentation for a minimum of 1 week, and not more than 4 weeks, before packaging. Racking to a secondary fermenter is not recommended except for beers requiring a long maturation, such as lagers, or beers requiring a second fermentation, such as sour ales and fruit beers
