Released in 1980, Magnum is very vigorous, high-yielding and stores very well, and for this reason is quickly increasing in popularity in Europe and the US. Magnum is used predominately as a base bittering hop, with subtle citrus flavours making it a great choice for lagers and pale ales.

Caring for Hop Plants

Growing hops is easy!  The instructions below are sent with each plant, and you can find more information in our Guide to Growing Hops article.

Here are some key points:

  • Hop plants are a hardy perennial, best planted as a bare root during the dormant winter months.
  • Hops like a well drained fertile soil and should be planted in open ground as soon as possible.
  • Make sure the hole is deep and the crown well covered.
  • Mark the spot with a screw peg.
  • Install your support (trellis, coir string) for the plant to climb up before the spring.
  • Small shoots should appear when the weather warms (April)
  • Train the shoots clockwise during May & June.
  • Harvest at the end of August.

Availability & Delivery

Dormant root stock becomes available in late November / December and is available to buy through to the following spring, as stocks last.
