I'd suggest for long term milk needs that you invest in goats if you have the space. They're better than all of the above, and a good source of meat and cheese, too.
I was raised on Alpura 2000, now called Alpura Clasica (It was from the future!) as soon as it became available. It has a very distinct flavor, better than Parmalat.
Parmalat SpA (BIT: PLT), is a multinationalItaliandairy and food corporation. Having become the leading global company in the production of UHT (Ultra High Temperature) milk. Today, Parmalat is a company with a global presence, having major operations in Europe, Latin America, North America, Australia, China and South Africa.
Still specializing in UHT milk and milk derivatives (varieties of yoghurt, cheese, butter, ice cream, etc.), the group also has an interest in fruit juices. These products are distributed under well-known brand names such as Lactis, Santal, Malù, and Kyr. Its worldwide operations include almost 140 production centres and more than 36,000 employees, while 5,000 Italian dairy farms are dependent on the company for the bulk of their business. Its shares are listed on the Milan Stock Exchange.
Go with the powdered. Condensed is good to have around for cooking, the powdered will (to me) taste better after its been chilled for a while.
