Sagatiba is a nice, above entry-level cachaça in Brazil and. arguably, the best option with regard to value for money around here (overall is Germana, hands down, but I'm not spending 30 quid on it every time I host a party...).
There is only one thing about Sagatiba that bothers me: the price! Back home, you can get a bottle online for less than 7 pounds. However, there is not much that can be done about it, so the point is: if ever in doubt between that and stuff like 51, Pitu or Velho Barreiro, ever go with the first one!
(But seriously, if you ever feel like tasting the true, caipira-favourite, cachaça, make the extra 10 quid effort and buy a bottle of Germana. It may be worth it!)
Cachaca is a commom drink in Brazil but Sagatiba is the one prefered by most people. My dad loves a double dose of it 'neat' and in a hot Sunday afternoon we use it to make caipirinhas, sipping it slowly while playing cards or just sitting on a hammock chatting. It is great to be able to buy the real thing in the UK.
