Alla har vi sett dem. (Eller kanske inte.) De \u00e4ggformade tankarna i betong eller i terrakotta. F\u00f6r n\u00e5gra \u00e5r sedan var de en sensation, nu k\u00e4nns det som om var och varannan vinmakare investerar i \u00e5tminstone en. Men spelar egentligen formen och materialet p\u00e5 j\u00e4stanken n\u00e5gon roll f\u00f6r vinets karakt\u00e4r?<\/p>\n

En chilensk forskare har unders\u00f6kt saken. Hon j\u00e4ste must fr\u00e5n sauvignon blanc i fyra olika typer av tankar: en vanlig cylindrisk st\u00e5ltank, en \u00e4ggformad betongtank, en \u00e4ggformad tank i polyeten och ett krus i terrakotta.<\/p>\n

Vid provsmakning av de fyra olika vinerna var det sv\u00e5rt att k\u00e4nna n\u00e5gon skillnad. Men i en teknisk analys var de olika. Vinerna fr\u00e5n de \u00e4ggformade tankarna hade mer restsocker \u00e4n de andra, 1,75 g\/l mot 1,36 g\/l. Betongtanken gav ett n\u00e5got h\u00f6gre pH, 3,22 (~l\u00e4gre syra\/friskhet) mot 3,15. St\u00e5ltanken tog fem dagar l\u00e4ngre p\u00e5 sig att j\u00e4sa klart och fick en n\u00e5got h\u00f6gre halt flyktiga syror. Intressanta resultat, men vem vet, kanske hade resultatet blir helt annorlunda med en annan druva?<\/p>\n

H\u00e4r finns mer information om experimentet med j\u00e4stankarna<\/a><\/p>\n
