  • Medd y Foel (Mead of the Foel)

    The winter-grazed clover meadow just below Y Foel

    If you followed a link to “” or ““: This post will be superseded by a dedicated “Medd y Foel” website once production gets into full swing. Last year we set up a new venture based around our apiary here at Y Foel. The primary goal is to produce excellent mead, […]

    After a couple of years our original stock of MVHR filters was used up. We then faced a dilema: The MVHR manufacturer was asking about 7 Euro for each G4 foam filter pad, and the online prices for a single Lindab F7 intake filter were between £40 and £60. Although […]

    ….or a bicycle with tyres that only last a month? We expect so much, from so many things we use every day. We have become accustomed to high levels of efficiency in design and energy use. We are so demanding with so many of the products of the industrial age. […]
