Liqueur Amaretto Castro. The Amaretto Castro liqueur is produced from 100% natural apricot kernelextracts, in a traditional way. It is a mildly bitter (“amaretto”), sweet liqueur with an intensely mature taste. The bitter almonds (apricot kernels) are immersed in alcohol and emit sweet hues of unique aromas with mild bitter tinges at the end. You can enjoy it straight or on the rocks, with fresh lemon juice, with green apple, in coffee, chocolate or tea, in sweets, combined with herbal liqueurs such as Sage Castro, with Coffee Castro liqueur or in cocktails.
