The lost block used to be produced from a single vineyard that was left on the vine a little longer to allow for greater fruit development. Now it is produced from a variety of vineyard in a house style sort of manner.
Tyrrell's Wines The Lost Block Semillon 2013
Lemon rind and orange peel makes me feel good that is higher in palate weight than I am used to for a wine of this age. The wine drinks well now but will look better with six months under its belt. Currently the wine is fruit forward but has enough acidity to hold it all together and finish vibrantly. I would drink this over many sav blanc but it still offers many of those good easy drinking characters that are associated with that variety.
Price: $18 but try the outlets as it might be cheaper
Drink: now - 2016
