Tagus is brewed in Portugal. I will guess that it takes its name from the Tagus River that flows from Spain, through Portugal, reaching the sea near Lisbon.
The beer is 4.5% ABV and pours a honey golden in color. Mine has some floaties, which is very likely not by design for a lager. There is a short head of white foam that rapidly dissipates. The aroma is very malty grain, a touch of straw and a touch of lager funk. The taste is very richly malted grain, a touch of malty sweetness, that is cut by the crisp carbonation. There are some counterbalancing hops evident, but no real bitterness on the finish. This is quite a malty golden lager, but good. I bet fresh on tap in Portugal it is an excellent lager.
