I got the Slipstream because I was in an expensive shop in Melbourne that specializes in smaller wineries, and I asked the staff to recommend something I could afford. It was really decent. The Columbia Crest (of Washington State) was Don's purchase after he tasted it at an event. It was great.
Don and I had these with my parents and spaghetti bolognese. They were quite nice.
Okay, now this wine is really special. It was left for us by the World's Best House Sitters (along with some Jelly Bellies and a pretty lamp and new linens. Really, you guys! We were happy to have you, without the gifts, even though we didn't get to see you!). I couldn't find the words at the time, and the wine is gone now, so here is some plagiarism from http://australianwinejournal.blogspot.com/2009/06/semillon-reviews.html:
PETER LEHMANN MARGARET SEMILLON 2003
Region: Barossa Valley, SA
Previously labelled as Reserve Semillon, Peter Lehmann's Margaret astounded critics with its inaugural 2002 release. Placed atop James Halliday's semillon list (96pts) and named Jeremy Oliver's Best Dry Semillon (95pts), it's diverted the attention of some of Australia's keenest semillon drinkers away from the Hunter Valley.
A more than worthy follow up which was included in the Adelaide Review's Top 100 Wines of 2008, the 2003 Margaret is youthfully bright; pale-yellow in colour, revealing an impressively expressive, fresh nose of buttery nuts, quince and citrus over a clear influence of mineral. Its radiant palate is beautifully full and intense, brimming with exceptional depth and complex rubbery texture; it unloads layers of mineral accented lemon, melon and grape characters, which build with intensity and structure. Secondary nuances of beeswax and fresh garden herbs develop from its inner core, with a vibrant presence of chiseled acidity leaving the mouth with persistent flavour and a delightfully clean aftertaste devoid of excessive dryness.
As a big fan of Hunter semillon I've been completely blown away and surprised by this near perfect, hot year Barossa semillon. Wow, what a wine! Drink to 2023. 96 points.
