Seasonal beers Seasonal beers are chiefly represented by March beers and Christmas beers. March beers French brewers market bière de mars ("March beer"), or bière de printemps ("Spring beer") over the month of March. It is produced in limited quantity starting from a variety of barley sown in the previous spring, harvested the previous summer and brewed at the beginning of the winter. It is in general a top-fermented ale of moderate strength (4.5% to 5.5%). In contrast to German Märzen beers, it is less hopped (less bitter) and weaker, although it can be darker (often by addition of caramel or other colourants), and slightly spiced. German Märzen is also fermented with lager, not ale yeast. Christmas beers There is a long-standing tradition of brewing strong ales in October for consumption in December. French Bières de Noël are rich and strong winter warmers as in other European countries. They are usually top fermented ales. Wheat beer French wheat beers are made by a number of large and small brewers, and not seen as belonging to any particular tradition.
