The US-American wine author Peter Liem was active in the wine trade
before his career. After a short time as publisher of the online wine portal "Riesling Report" from 2000 to 2002, he started working for the magazine Wine & Spirits
in 2004 as a senior editor and wine critic
for Germany, Alsace, Loire and Austria. After he had been particularly interested in champagne
for some time, he moved to Champagne in 2006. Since 2009 he has been the publisher and author of the online portal "ChampagneGuide.net" for wines and producers from Champagne. He regularly writes articles for the San Francisco Chronicle, World of Fine Wine
and Zester Daily.
