MORETTI LA ROSSA. Doppio Malto. Birra Moretti La Rossa is a double malt beer produced using 100% high quality barley malt. This gives it a full, caramelised malt flavour and an intense aroma of roasted malt. Its distinctive amber colour originates from the type of malt used when brewing, a special malt which is dried and roasted. Source: Moretti Brewnig.
