smorgan;
Cachaca as you are probably aware is clear, without any molasses typical of other rums in the world. The better made brands are akin to one enjoying Grappa, as there are soft, smooth, and harsh varietals made.
There are now over 400 different brands of Cachaca made in Brasil, some expressly made for the tourism trade, with a price to match. You or your daughter can sample many of the selections at some of the Cachaca bars that have developed over the years, but advisedly on a full stomach.
I've been to 4 various plants that manufacture the spirit. in greater Brasil. Ypioca, as mentioned by SOCAL is local to Fortaleza and the Nordeste, with a nice museum and distilling plant worth visiting if you visit there. There is a good 150 aged Ypioca worth buying for anyone's collection.
Amarula, originally a South African liquor has taken hold in Brasil, and is quite popular, primarily as an after dinner drink. Post Churrasco or Rodizio, it is excellent with, or mixed in a domestic coffee. You can also find it produced in Brasil under Marula or Amarula.
Incidentally, 1 bottle of Cachaca in Europe is easily 30 to 50 Euros here. A great gift, but only for those who would enjoy it. Wrap it well and tuck it in your checked luggage. It should make the trip safely to North America or Europe, but after the Customs or Zoll inspectors see it, one can only hope and pray.
Bonne Chance !
