  The presence of methanol among the common ice components in interstellar
clouds and protostellar envelopes has been confirmed by the James Webb Space
Telescope. Methanol is often detected in the gas phase toward lines of sight
shielded from UV radiation. We measured the volumetric density of methanol ice,
grown under simulated interstellar conditions, and the infrared spectroscopy at
different deposition temperatures and during the warm-up. The IR band strengths
are provided and the experimental spectra are compared to those computed with a
model. The transition from amorphous to crystalline methanol ice was also
explored. Finally, we propose new observations of methanol ice at high
resolution to probe the methanol ice structure.
