I'm a partial something brewer that greatly prefers LME over DME.
Northern Brewer is the only supplier that I am aware that sells home brewer quantities of organic LME. They also have a decent number of organic grains, probably all Briess. If you are an all-grain or a DME Brewer then there are some other vendors.
If you buy New Zealand hop varieties, then they are all organic. They might not be labelled as "organic," but New Zealand's standards for all agricultural products are stricter than Oregon's organic labelling standards which are stricter than Federal U.S. standards to qualify as organic.
I believe all dry yeast is organic. Liquid yeast has malt extract which is rarely organic. Look for Omega.
