The winery is located near the municipality of Alaró on the Balearic island of Mallorca, high up in the Tramuntana mountains. The name is derived from the first name of the owner (Spanish spelling for "Michael"). It is owned by the German family-owned company Bionorica (the world's leading manufacturer of herbal medicines) in Neumarkt in the Upper Palatinate. Today, the company is managed in the third generation by Prof. Dr. Michael A. Popp. He explains the objectives of the new viticulture business branch: "Our aim is to produce wine that is an international leader in both its sensual and health-promoting dimensions" With the 1998 purchase of the "Es Castellet" estate, which is threatened by decay, the foundation stone for high-quality wines was laid. Major investments were made in vineyards, vines, modern technology and production/bottling facilities. Núria Tuduri is responsible as oenologist.
The vineyards are spread over several areas and cover a total of 38 hectares. The heart of the area is a 3.8 hectare steep slope where the vines grow on an ancient stone staircase that has been extensively restored. The wines grown here are appropriately named "Stairway to Heaven". The varieties Cabernet Sauvignon, Merlot, Syrah and Sauvignon Blanc are cultivated. The vineyards are cultivated according to the rules of organic viticulture. This includes the promotion of beneficial organisms and a minimum use of chemical agents.
Under the brand name "Castell Miquel" mainly red wines are pressed, but also white wines. The red wines are fermented in ultra-modern mash tuns with an oak casing. Cabernet Sauvignon and Shiraz are aged for 12 months in Hungarian and French barriques. The wines are marketed in the quality category Landwein (VT) "Serra de Tramuntana-Costa Nord". Since 2007, a Cava (sparkling wine) from Syrah is also produced. In Porreres there are another 18 hectares of vineyards, from which a VT "Illes Balears" is produced. And in the DO area Binissalem, 15.5 hectares are cultivated. The bottles are bottled with the Vinolok glass closure. As with a medicine, the ingredients that are beneficial to health are scientifically analysed and (à la package insert) identified on the back label. Around 180,000 bottles of wine are produced annually.
